I want to create the Dialog with progress bar to show the hours and mins like shown below, is anyone able to help me?
Is there a way to show some warning/error when Android resource id does not belong to layout inflated in Activity?
Following is simple example, but in more complex layouts it is much harder to track down such issues as they can only be found during run-time. I would like to be able to catch them at compile-time.
MainActivity initialization
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// how to prevent erroneous usage of R.id.text2 at compile time
TextView t = (TextView) findViewById(R.id.text2);
}
activity_main.xml

Good afternoon,
I'm doing a TableLayout and need to know how to have a column that can have text or an image.
That is, if a selected option need to show a picture in this column, if this option is not selected need to show a text.
This variation is row to row. I can have a row with image at this column and text on next row
I am creating a friend finding app in Android Studio 1.1.0 which incorporates the Google Maps API. This does not allow me to create any widgets on my current activity so I would like to create a slider (Similar to Facebook app on IOS) in which data can be displayed.
Any help will be appreciated.
I am implementing a tablet application which at left side shows list of my pdf files and on the right side I want to show the pdf file data. How can I do that? and I want to open Pdf in fragment. Requirements: - Must be able to open PDF using Fragments in Android. - Should load PDF from local file. - User must be able to navigate pdf pages using simple Vertical Scroll. - User must be able to zoom with pinch (finger gesture) - No other controller on the screen. - PDF should cover the all space available
I am using RadioButton in my layout. Where i have provided background to the RadioButton. Below is the code
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="horizontal">
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@null"
android:background="@drawable/rb_spain"
android:id="@+id/am_rb_spain" />
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@null"
android:background="@drawable/rb_germany"
android:layout_marginLeft="@dimen/margin_15"
android:layout_marginRight="@dimen/margin_15"
android:id="@+id/am_rb_german" />
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@null"
android:background="@drawable/rb_english"
android:id="@+id/am_rb_english" />
</RadioGroup>
RadioButton background drawable
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://ift.tt/nIICcg" >
<item android:state_checked="false" android:drawable="@drawable/ic_spain" />
<item android:state_checked="true" android:drawable="@drawable/ic_spain_pressed" /> //pressed image is Large in size
<item android:drawable="@drawable/ic_spain" /> <!-- default -->
</selector>
I have saved the selection in TinyDB so that app will remember my selection whenever i open my app. But whenever i open my app the default selected RadioButton background Appears Large. I have taken all the images of same size in drawable's with same padding.
First flag is Default selected here. But it appear to be slightly large in size
Now i have pressed 2nd flag. But first flag is not coming to its normal state.
I am trying to inflate and display a LinearLayout with a specific height but when displayed the height always gets converted to wrap_content. My layout is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://ift.tt/nIICcg"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="@dimen/dialog_title_height"
android:padding="@dimen/default_padding"
android:layout_weight="1">
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:text="Scan for devices" />
<ProgressBar
android:id="@+id/progressBarScanning"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
</LinearLayout>
It seams fine at first but when I set the ProgressBar visibility to View.GONE then the layout height shrinks to the size of the TextView which is much smaller than the set layout_height on the parent layout.
But, if I wrap the views in a 2nd LinearLayout with the specified height and set the parent to wrap_content then it works just fine. Like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://ift.tt/nIICcg"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="@dimen/default_padding"
android:layout_weight="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="@dimen/dialog_title_height">
<TextView
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:text="Scan for devices" />
<ProgressBar
android:id="@+id/progressBarScanning"
android:layout_width="wrap_content"
android:layout_height="match_parent" />
</LinearLayout>
</LinearLayout>
But now of course AndroidStudio complains that the 2nd LinearLayout is useless.
What is the proper way to do this?
There are 10 buttons on absolute layout and I want that onClick a popwindow will show and inside the window I want 4 ImageViews and 4 ImageButtons (ImageButtons will used for playing an audio). Kindly help me out. The popup window's orientation will be landscape and align to the right side.
I want to achieve this layout screen(attached here-in) in android, i tried with designing the page as per below code, but while testing the screen on device it went horribly slow.
On browsing few links, came to know that it has happened due to excessive nesting of linear layouts, same is reflected in hierarchy viewer.
So I wanted to understand what should be best go here to design this app ?
PS : I am new bie to android world, so want to learned from your expert advise asap.

After updating to Android Studio 1.2.1.1, I created a new fresh blank project and created a layout.xml
Shortly after creation, I decided to look at the preview. I went in and I saw this:
The following classes could not be instantiated: - android.support.v7.internal.widget.ActionBarOverlayLayout (Open Class, Show Exception, Clear Cache) Tip: Use View.isInEditMode() in your custom views to skip code or show sample data when shown in the IDE Exception Details java.lang.NoClassDefFoundError: Could not initialize class android.support.v7.internal.widget.ActionBarOverlayLayout at java.lang.reflect.Constructor.newInstance(Constructor.java:408) at android.view.LayoutInflater.inflate(LayoutInflater.java:482) at android.view.LayoutInflater.inflate(LayoutInflater.java:414) at com.android.layoutlib.bridge.bars.BridgeActionBar.(BridgeActionBar.java:84) at com.android.layoutlib.bridge.bars.AppCompatActionBar.(AppCompatActionBar.java:56) Copy stack to clipboard
I have never seen it before and I had never encountered it before. Anyone have any idea how to fix this?
in our app, I'm loading an initial webview. Then in order to allow users to see chat history, I want to add new webviews on top on that initial one. The way I do that now is to have a linear layout wrapping the initial webview; this LinearLayout is called webview_wrapper and is in a ScrollView. Then, using a ScrollViewListener interface, when the user scrolls up past a set coordinate I create a new webview, call it newWebView, and call webview_wrapper.addView(newWebView, 0), the problem I'm having is that I want to do the loading and adding of the webview off the screen, then the user can continue to scroll up. This adding and scrolling happens inside of an onAnimationEnd method of an AnimationListener(while I make the post request for webview).
I feel like I've tried every way like calling scrollTo or scrollBy after adding the view but it's only scrolling partially. What is the best way to do this?
I am using TwoWayView library from Lucas to create a horizontal ListView. Everything works fine on GS3, Galaxy Note 2 Android 4.1.2 & Android 4.3.
However, I installed my app on my coworker Motorola G Android 4.44, and the ListView did not show any image. I can click on them, but I can't see any image. It only shows red or transparent color.
ListView Adpater:
public class ListViewAdapter extends BaseAdapter {
private List<ListViewObject> ObjectList;
private Context mContext;
public ListViewAdapter(Context context, List<ListViewObject> newList){
this.mContext = context;
this.ObjectList = newList;
}
@Override
public int getCount() {
return ObjectList.size();
}
@Override
public ListViewObject getItem(int position) {
return ObjectList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder = new ViewHolder();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = inflater.inflate(R.layout.listview_layout, parent, false);
viewHolder.imageView = (ImageView)convertView.findViewById(R.id.ListViewImage);
viewHolder.layout = (RelativeLayout)convertView.findViewById(R.id.ListViewLayout);
convertView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder)convertView.getTag();
}
Picasso.with(mContext)
.load(getItem(position).getImageUrl())
.resize(100, 100)
.centerCrop()
.into(viewHolder.imageView);
return convertView;
}
class ViewHolder {
RelativeLayout layout;
ImageView imageView;
}
}
ListView Layout:
<RelativeLayout xmlns:android="http://ift.tt/nIICcg"
android:id="@+id/ListViewLayout"
android:layout_width="52dp"
android:layout_height="43dp" >
<ImageView
android:id="@+id/ListViewImage"
android:layout_width="50dp"
android:layout_height="40dp"
android:scaleType="fitXY"
android:layout_marginLeft="2px"
android:layout_marginTop="2px" />
Main Layout:
<org.lucasr.twowayview.TwoWayView
xmlns:android="http://ift.tt/nIICcg"
xmlns:app="http://ift.tt/GEGVYd"
android:id="@+id/TwoWayView"

android:layout_width="match_parent"
android:layout_height="43dp"
android:layout_marginTop="595dp"
android:background="@color/transparent"
android:drawSelectorOnTop="true" />
MainActivity:
public void ListView_Load() {
for (File file : listFile){
mListViewObject = new ListViewObject();
mListViewObject.setImageUrl("file:///" + file.getAbsolutePath());
ListViewObject_List.add(mListViewObject);
}
listViewAdapter = new ListViewAdapter(this, ListViewObject_List);
TwoWayListView.setAdapter(listViewAdapter);
}
I just can't figure it out why this is happening.
can someone please guide me on this?
Thank you very much for your help.
My goal is to use OpenGL ES 2.0 with Google Maps. I would like to create an app that follows the user as they are traveling from point A to point B. I realize that this can be done using Google Maps addPolyline to draw a line, but I want to use OpenGL instead in order to show overlap of paths. I'm currently receiving an error which is due to incorrectly setting up the GLSurfaceView.
My code in the GoogleMapsTracker class is as follows:
private MapView mapView;
private GoogleMap map;
private GLSurfaceView mGLSurfaceView;
/**
* Use this factory method to create a new instance of
* this fragment using the provided parameters.
*/
public static GoogleMapsTracker newInstance() {
GoogleMapsTracker fragment = new GoogleMapsTracker();
fragment.setRetainInstance(true);
return fragment;
}

super.onCreate(savedInstanceState);
mapView = (MapView) getActivity().findViewById(R.id.map);
mGLSurfaceView = new GLSurfaceView(getActivity());

final ActivityManager am = (ActivityManager) getActivity().getSystemService(Context.ACTIVITY_SERVICE);
final ConfigurationInfo cInfo = am.getDeviceConfigurationInfo();
final boolean supportsEs2 = cInfo.reqGlEsVersion >= 0x20000;
if(supportsEs2){
// Request an OpenGL ES 2.0 compatible context
mGLSurfaceView.setEGLContextClientVersion(2);
// Set the renderer to out demo renderer, defined below
mGLSurfaceView.setRenderer(new GoogleMapsRenderer(getActivity()));
} else {
// This is where you could create an OpenGL ES1.x compatible
// renderer if you wanted to support both ES 1 and ES 2
Log.d("Does Not Support ES 2.0", "Does NOT Support ES 2.0");
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v;
if(SettingsActivity.mUnits){
v = inflater.inflate(R.layout.google_maps_tracker_metric, container, false);
} else {

}
// Gets the MapView from the XML layout and creates it
mapView = (MapView) v.findViewById(R.id.map);
mapView.onCreate(savedInstanceState);
// Gets to GoogleMap from the MapView and does initialization stuff
map = mapView.getMap();
map.getUiSettings().setMyLocationButtonEnabled(true);

I'm quite certain that I'm not adding my views together properly. If anyone can point out my mistakes and a better way of implementing this idea that would be much appreciated.
I am using Android Studio 1.2.1.1. When editing an xml layout file such as "\large-hdpi\my-layout.xml", a preview is generated in the right hand panel. In this case I have the Nexus 7 selected which is 800x1280. I expect the layout to be "large-hdpi" which it is, and I expect "hdpi" drawables to be used which it are not. The problem is, I see no way to find out exactly which drawable resource folder is being used for the preview. Sorry if it's obvious but I just don't see it.
I searched everywhere but I cannot find a solution for this simple question: I'm using a predefined layout R.layout.simple_list_item_1 but I cannot find the way to modify the text color of the TextViews inside it.
I'm trying to understand how the drawable folders in Android works. I found that in the resource folder in our project, it has the following folders:
res/drawable-ldpi/
res/drawable-ldpi-v8/
res/drawable-ldpi-v11/
res/drawable-mdpi/
res/drawable-mdpi-v8/
res/drawable-mdpi-v11/
res/drawable-hdpi/
res/drawable-hdpi-v8/
res/drawable-hdpi-v11/
res/drawable-xhdpi/

Can someone please educate me on how the fallback mechanism on these folders works? Also what does v8 and v11 mean?
Im pretty new at developing android applications and i want to have to different layouts for 4" phone and 5" phone. Ive tried using layout-sw320dp for 4" phone(Nexus S) and layout-sw480dp for the 5" phone(Nexus 5).
However the layout gets cramped up while using the nexus S. Ive tried using layout-small and layout-normal. Didnt help.
Thanks Sahil
My question is more informative. I just want to know how to make such design. I found android application called "weather timeline" and inside of that application between CardViews (as I understand) they used this element which I pointed out in picture below. I think its just ImageView but how to set it as here. It will be interesting to know any idea about that! Thanks for attection!
I'd like an existing smartphone app to look good a smartwatch. What is the correct resource directory name for Wear layouts?
I tried res/layout-wear, but the console says that this resource directory name is invalid.
I have a LinearLayout with horizontal orientation in which I add some TextView and EditText dynamically. My problem is when the TextView is long, it is cut off (by height) and the EditText is invisible.
Adding padding to the views didn't solve it. When setting the LinearLayout minHeight value, the TextView is displayed correctly but the EditText is still invisible.
<LinearLayout
android:id="@+id/content_content"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"></LinearLayout>
LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(
LinearLayout.LayoutParams.WRAP_CONTENT,
LinearLayout.LayoutParams.WRAP_CONTENT);
for (int i = 0; i < cntCount; i++) {
TextView cntView = new TextView(getActivity());
cntView.setLayoutParams(params);
cntView.setText(cnt.get(i));
contentContentView.addView(cntView);
EditText answerView = new EditText(getActivity());
answerView.setLayoutParams(params);
answerView.setId(i);
answerView.setHint("......");
contentContentView.addView(answerView);
}
EDIT
I have found the solution and created a library. For those interested you can download it here
I am stuck, please help me, I have this,
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout
xmlns:android="http://ift.tt/nIICcg"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/background"
android:id="@+id/swipeRefresh">

android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/contentLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"></LinearLayout>
</ScrollView>
</android.support.v4.widget.SwipeRefreshLayout>
Programmatically i am adding Linear Layout containing ImageView and TextView into LinearLayout of this xml file. Its okay for me. Now in Java i am doing,
refreshLayout = (SwipeRefreshLayout)view.findViewById(R.id.swipeRefresh);
refreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
refreshLayout.setRefreshing(true);
( new Handler()).postDelayed(new Runnable() {
@Override
public void run() {
refreshLayout.setRefreshing(false);
}
}, 5000);
}
});
Inside setOnRefreshListener I want to add new LinearLayout containing ImageView and TextView on the top of my previous view. That means all my previous LinearLayout which I added programmatically will be placed after new Layouts keeping unchanged.
I can't move from here. Any suggestion will be appreciated.
am trying to draw sloped rectangle upper edge shape and use it as linear layout background as in the picture:
here is the link to the design am trying to achieve: http://ift.tt/1ApcyX7
I tried to draw a rectangular and rotate it but it didn't work fine.
so how to create that shape.
sorry about grammar mistakes, am not fluent :P.
I set-up a list of items for the MainActivity. Today only one item this menu.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://ift.tt/nIICcg"
xmlns:app="http://ift.tt/GEGVYd"
xmlns:tools="http://ift.tt/LrGmb4"
tools:context="fr.vincelec.sunshine.sunshine.app.ForecastFragment">
<item android:id="@+id/action_refresh"
android:title="@string/refresh"
app:showAsAction="never"/>
</menu>
Also Here is the code to enable the menu:
@Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater){
inflater.inflate(R.menu.forecastfragment, menu);
}
@Override
public boolean onOptionsItemSelected(MenuItem item){
int id = item.getItemId();
if (id == R.id.action_refresh) {
FetchWeatherTask weatherTask = new FetchWeatherTask();
weatherTask.execute();
return true;
}
return super.onOptionsItemSelected(item);
}
But when I launch the program in my Android phone, and click on the menu, I see twice the item "Refresh", not only one item ...
I checked if there is something in MainActivity.java or main.xml but without success, It's only on my fragment file "ForecastFragment.java" (where the piece of code shown before is from) that I call the R.menu.forecastfragment .
Thanks a lot for your help :-)
I have two relative layout inside linear layout. I want the first relative layout left align and the second relative layout right align. I set the following line in the second relative layout but it is not working.

My current code gives an output like this. Second layout start after first layout. I want it to start from the right from parent.
So my question is how can I set the second relative layout right align.
Thank you.
I am using list view footer which is just a button. Whenever i am updating the list with load more button it add extra space at the bottom. Also i am trying to remove the footer when all d data is loaded.

I'm trying to get control buttons to pop on/off screen when the screen is tapped. They will overlay a video. The problem I'm running in to is how to create a touch event for a layout that has been inflated.
The routine is as follows:
1) set initial content to the video;
2) inflate layout(XML), that contains the controls, over the top of the video;
3)(NEED TO DO) create onTouch event for the newly inflated layout that hides/shows the buttons when the user taps the screen.
Thanks for any help!

ps. As you can notice from the screenshot, a second problem arises: Why the first 2 TextView get stretched in height? How can I fix this unpredictable behavior?
I am working on an android application in which there is a navigation drawer, when I click on one of the fragments it becomes extensively slow? Can anyone explain why this is happening? I have used linear layouts in that particular fragment where I am landing
I am trying to display products list using CardView for my android app. I have an ImageView that is complete so I want to display other products inside the card view which will be located just below the image view. Currently I am working on my XML file for my Activity but the only way I can display the Card View is by removing the android:layout_below="@+id/custom_indicator2" on my CardView element. When I do this, the card view displays on top of my Image View. How can I do this while working on a Scroll View where in case I add more content to my Card View, I can just scroll down on my layout?

Update: I have tried debugging my application with an android phone that has no menu button and noticed something different. My interface shows same way as before without the cardview as below.
When I try entering text onto my searchview then my cardview shows like below
This is how it was displaying initially on my Samsung which has a menu button.
Please note that all I am doing on my activity is call my onCreate method which sets content to the given XML. I thought it was not necessary to give my Activity.java code because of this.
I want to make an app where I can access all the notifications which comes to the notification center. Any help will be appreciated.
Please suggest some blog or article.I didn't find any useful info.
Thanks in advance.
I have the following layout for one of my screens. I have used Toolbar instead of ActionBar to get the desired look of overlying FAB. The problem is when i scroll the list, the shadow doesn't show transparency. How to deal with this?
Here is complete layout xml:

I need to implement function of changing the application theme up on button click. I have already changed successfully style of buttons, edittexts and textviews. But faced the problem of changing style for Spinner.
The only successful change is change of background color:
spinnerRoutes.setBackgroundResource(R.drawable.dark_theme_spinner_background);
BUT only background of title row changed. I need also to change textColor of rows and items, and background of spinner rows.
I have already tried alot of similar stackoverflow solutions but none of them worked.
Is it even possible to change style of spinner programatically?
This is my first post here. I just learned Android programming and come to this problem. I have searched a bit and found some solutions but I couldn't make my code works. So I want to know which part of my code or implementation is wrong.
So, the problem is I want to make a layout which will stays the same proportion on different screen sizes and orientation. Here are my code:
activity_main.xml
<LinearLayout
xmlns:android="http://ift.tt/nIICcg"
xmlns:tools="http://ift.tt/LrGmb4"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:baselineAligned="false"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="150dp" >
<TextView
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:gravity="left"
android:id="@+id/textView1"/>
<TextView
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:gravity="right"
android:id="@+id/textView2"/>
</LinearLayout>
<LinearLayout
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:id="@+id/textView3"/>
</LinearLayout>
<LinearLayout
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:gravity="left"
android:id="@+id/textView4"/>
<TextView
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="fill_parent"
android:gravity="center"
android:id="@+id/textView5"/>
<TextView
android:layout_weight="1"
android:layout_width="0dp"

I can't post screenshot at the moment, because it said "You need at least 10 reputation to post images."
So, I want to divide the screen by 3 parts vertically, and divide the top part by 2 horizontally and the bottom part by 3 horizontally and maintain their proportion regardless of screen size, resolution, and orientation.
The only part that didn't work is the top block, on the code I set it to android:layout_height="150dp" because the layout somehow is broken if I set those to android:layout_height="fill_parent". But this doesn't make the layout to be proportional if I change the orientation. Any help will be appreciated.
Thank you.
I have a new Activity with related layout which works fine. Except the ImageView(s) don't cover the whole width of my screen.
I'm using Android Studio (the latest stable version) and surprisingly inside the IDE the preview of my layout looks fine. But when I run the app on my device (or emulator) it doesn't cover the whole screen.
Here is my layout design:
<RelativeLayout xmlns:android="http://ift.tt/nIICcg"
android:id="@+id/root"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ScrollView
android:id="@+id/scrollView1"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout xmlns:android="http://ift.tt/nIICcg"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="@+id/cat_food"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="@drawable/cat_food" />
<ImageView
android:id="@+id/cat_drink"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="@drawable/cat_drink" />
<ImageView
android:id="@+id/cat_coffee"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="@drawable/cat_coffee" />
<ImageView
android:id="@+id/cat_shopping"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="@drawable/cat_shopping" />
<ImageView
android:id="@+id/cat_offers"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="@drawable/cat_offers" />
</LinearLayout>
</ScrollView>
<include
android:id="@+id/action_bar"
layout="@layout/layout_actionbar" />
Any idea what I'm doing wrong here?
Thank you for your help.
P.S. I tried wrap_contents, match_parent, fill_parent already and none of those solved the problem.
I've got 3 TextView, and I want to create a custom selector drawable which:
The TextViews:
<LinearLayout android:id="@+id/info" android:layout_marginTop="68dp"
android:layout_width="wrap_content" android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:orientation="horizontal">
<TextView android:id="@+id/tour1"
android:paddingLeft="10dp" android:paddingRight="10dp"
android:paddingTop="8dp" android:paddingBottom="8dp"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:background="@drawable/back"
android:gravity="center"
android:text="Tour \n disponibili \n 21"/>
<TextView android:id="@+id/tour2" android:layout_toRightOf="@+id/tour1"
android:paddingLeft="10dp" android:paddingRight="10dp"
android:paddingTop="8dp" android:paddingBottom="8dp"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:background="@drawable/back"
android:gravity="center"
android:text="Tour \n prenotabili \n 16"
android:layout_marginLeft="16dp"/>
<TextView android:id="@+id/tour3" android:layout_toRightOf="@+id/tour2"
android:paddingLeft="10dp" android:paddingRight="10dp"
android:paddingTop="8dp" android:paddingBottom="8dp"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:background="@drawable/back"
android:gravity="center"
android:text="Tour \n preferiti \n 3"
android:layout_marginLeft="16dp"/>
</LinearLayout>
My Drawable selector file, back.xml:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://ift.tt/nIICcg">
<item>
<shape android:shape="rectangle" >
<stroke android:width="1dip"
android:color="#4fa5d5"/>
<corners android:radius="7dp"/>
</shape>
</item>
<item android:state_pressed="true">
<shape android:shape="rectangle" >
<stroke android:width="5dip"
android:color="#ff0000"/>
<corners android:radius="7dip" />
</shape>
</item>
I would like to know how:
"?android:attr/selectableItemBackground"Unfortunately, I wasn't able to implement any of the above. In my example, the TextViews always show the first item (the one without the android:state_pressed="true" attribute) selected and when I press them they never switch to the item with the android:state_pressed="true" attribute.
Where are the flaws in my code?
This question already has an answer here:

I want to define an onClick Listener for an EditText in the Layout-XML of may activity, but it always fails with an obscure Exception. This is the relevant part of my layout file:
<ImageView
android:layout_gravity="center_horizontal|top"
android:layout_rowSpan="3"
android:src="@drawable/ic_action_event"
android:onClick="onCreationClicked"
/>
<EditText
android:id="@+id/creation_edit"
android:focusable="false"
android:clickable="true"
android:layout_gravity="fill_horizontal"
android:hint="@string/enter_creation"
android:onClick="onCreationClicked"
style="@style/PickerEditText"
/>
When I click on the ImageView the associated method is executed and a DialogFragment is started. When I click on the EditText I get the following Exception:
java.lang.IllegalStateException: Could not find a method onCreationClicked(View) in the activity class android.support.v7.internal.widget.TintContextWrapper for onClick handler on view class android.support.v7.widget.AppCompatEditText with id 'creation_edit'

I am currently testing on a Samsung S4 (Android 5.0.1) API 21 and AppCompat Library in Version v7 22.1.0
Any ideas?
I'm writing an android app using romannurik`s Android-SwipeToDismiss using google cardview items. Swiping the cards is enabled in the app using the above romannuriks library.
Currently my problem is in implementing, another view come in background while i'm swiping the card, just like the implementation in gmail where I can see archive and undo while I'm swiping the card.
Any ideas would be greatly helpful.
I have been looking on how to highlight a focused edit text form field in an Android app.
When I focus my email field, there is no visual feedback.
What sort of visual feedback should I provide ? Is there a standard on what the user expects ?
I was thinking of some background color highlight or some field border color.
Any way to achieve this ?
My layout is:
<EditText
android:id="@+id/login_email_edittext"
style="@style/editext_graybg"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="@drawable/ic_username"
android:drawableStart="@drawable/ic_username"
android:hint="@string/login_email_hint" >
<requestFocus />
</EditText>
And the style:
<style name="editext_graybg" parent="android:Widget.EditText">
<item name="android:background">@drawable/editext_bg_gray</item>
<item name="android:drawablePadding">@dimen/pad_10dp</item>
<item name="android:ems">10</item>
<item name="android:inputType">textEmailAddress</item>
<item name="android:paddingLeft">@dimen/pad_10dp</item>
<item name="android:paddingRight">@dimen/pad_10dp</item>
<item name="android:textColor">@color/black</item>
<item name="android:textSize">@dimen/txt_18sp</item>
</style>
I want to design progress indicator which will be changed dynamically(increase) after each user input.
View with background color and change height param dynamically, But i am asking if there is a library that may give me beautiful color effects.I'm trying to remove RelativeLayout.END_OF from a view's layout parameters which is added programmatically, but it seems that just writing viewLayoutParams.removeRule(RelativeLayout.END_OF) doesn't work and I don't know why!
I'm trying to make a live preview based on options and here they are my codes.
XML:
<RelativeLayout
android:id="@+id/liveExample"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/liveExampleLabel">
<TextView
android:id="@+id/iranianDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Monday, 8 Bahman 1370"
android:textAppearance="@style/AppTheme.Text.IranianDate"
tools:ignore="HardcodedText"/>
<TextView
android:id="@+id/islamicDate_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_below="@id/iranianDate"
android:text="@string/islamic"
android:textAppearance="@style/AppTheme.Text.IslamicLabel"/>
<TextView
android:id="@+id/islamicDate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="8 Rajab 1436"
android:layout_below="@id/iranianDate"
android:textAppearance="@style/AppTheme.Text.IslamicDate"
tools:ignore="HardcodedText"/>
</RelativeLayout>
Java:
private void updateLivePreviewDatesLayout(boolean isChecked) {
RelativeLayout.LayoutParams iranianDateLayoutParams = (RelativeLayout.LayoutParams) iranianDate
.getLayoutParams();
RelativeLayout.LayoutParams islamicDateLayoutParams = (RelativeLayout.LayoutParams) islamicDate
.getLayoutParams();
if (isChecked) {
iranianDateLayoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
islamicDateLayoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
islamicDateLayoutParams.setMarginStart(0);
islamicDateLayoutParams.removeRule(RelativeLayout.END_OF);
} else {
iranianDateLayoutParams.removeRule(RelativeLayout.CENTER_HORIZONTAL);
islamicDateLayoutParams.removeRule(RelativeLayout.CENTER_HORIZONTAL);
if (displayIslamicLabel.isChecked()) {
islamicDateLayoutParams.setMarginStart(8);
islamicDateLayoutParams.addRule(RelativeLayout.END_OF,
R.id.islamicDate_label);
}
}
iranianDate.setLayoutParams(iranianDateLayoutParams);
islamicDate.setLayoutParams(islamicDateLayoutParams);
}
centerHorizontal.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
editor.putBoolean("w_centerHorizontal", isChecked).apply();
updateLivePreviewDatesLayout(isChecked);
}
});
It works for the first time (removing toEndOf layout parameter) but for the next time, it won't be removed because I added the parameter programmatically.
UPDATE
I need to add the layout_toEndOf layout parameter to the view because the default position of the view is related to another view which they should be next together and after that, the view may be positioned at the center of its layout so I should remove the RelativeLayout.END_OF and instead add RelativeLayout.CENTER_HORIZONTAL parameter. It's good to know that these two parameters won't work together and RelativeLayout.END_OF is more powerful that the other parameter.
Screenshots
Before checking the option: The default position of the "4 Sha'ban 1436" is end of the "Islamic" label.
After checking the option: the "4 Sha'ban 1436" not positioned at center because the RelativeLayout.END_OF parameter is not removed correctly and that's the problem!

I am using RadioButton in my layout. Where i have provided background to the RadioButton. Below is the code
<RadioGroup
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="horizontal">
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@null"
android:background="@drawable/rb_spain"
android:id="@+id/am_rb_spain" />
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@null"
android:background="@drawable/rb_germany"
android:layout_marginLeft="@dimen/margin_15"
android:layout_marginRight="@dimen/margin_15"
android:id="@+id/am_rb_german" />
<RadioButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:button="@null"
android:background="@drawable/rb_english"
android:id="@+id/am_rb_english" />
</RadioGroup>
RadioButton background drawable
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://ift.tt/nIICcg" >
<item android:state_checked="false" android:drawable="@drawable/ic_spain" />
<item android:state_checked="true" android:drawable="@drawable/ic_spain_pressed" /> //pressed image is Large in size
<item android:drawable="@drawable/ic_spain" /> <!-- default -->
</selector>
I have saved the selection in TinyDB so that app will remember my selection whenever i open my app. But whenever i open my app the default selected RadioButton background Appears Large. I have taken all the images of same size in drawable's with same padding.
First flag is Default selected here. But it appear to be slightly large in size
Now i have pressed 2nd flag. But first flag is not coming to its normal state.

I'm using Nexus5 for testing application and I got issue that is Navigation bar hides Bottom Layout
Main container is RelativeLayout which has LinearLayout on the bottom. other devices are fine and showing well but only Nexus5 has that issue because I think it has navigation bar on the bottom of screen.

I thought to use a scrollview, but I don't know how to use it.
WHen the keyboard appears I would to show :
Is there a way to resolve my problem ?
OK first I'm not actually moving buttons I'm moving imageviews that have an onclick listener. What I want to do is drag multiple imageviews around inside a layout. I was going to use a FrameLayout but it seems that wont work for multiple items.
Can anyone tell me which layout is suitable for this?
thanks in advance
I am new to android development, so please bear with me. My app elements (button color, background color, text color, divider color etc.) uses colors from the colors.xml using "@color/mycolor" for example.
My colors.xml looks like:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="mycolor">#202020</color>
<color name="white">#FFFFFF</color>
<color name="whitehint">#50FFFFFF</color>
<color name="primary">#673AB7</color>
<color name="primary_dark">#512DA8</color>
<color name="primary_light">#D1C4E9</color>
<color name="accent">#794cc9</color>
<color name="primary_text">#212121</color>
<color name="secondary_text">#a4a4a4</color>
<color name="icons">#FFFFFF</color>
<color name="divider">#B6B6B6</color>
</resources>
Now I have a menu where the user can select a different theme which I want to use a second colors2.xml for example which will have the same color names but a different hex code for the keys. How do I go about which xml file does my app references?
I'm making an Android news app and when I or the user would access a list of news, each news would take the whole screen and would be divided in two parts (50/50) : first part would be the image and the other half would be the textviews (for the title, date and article). A couple of apps are using the same trick.
I've tried many options but I cannot manage to make them fit into my screen and get what I'm looking for.
As you will see I've added the layout_weight parameter but it does not make any difference at all.
Any idea anyone ??

I am trying to record FM radio audio stream. I am able to record with one audio source which is 9 for Motorola.
But when i tried with different phones it not working. So i wondering how to get this audio source dynamically.
This is how i am recording
//RX_SRC is the FM receiving Antenna
mRecorder = new AudioRecord(10, sampleRateInHz,
channelConfigIn,
AudioFormat.ENCODING_PCM_16BIT,
bufferSizeInBytes);
Please help me.
I'm looking to view the source code for the Layout Preview (generated from XML) in Android Studio. Does anyone know which files the relevant code is in within the SDK, or is it somewhere else entirely? I only ask because there are so many source files for Android Studio and the Android SDK, it would take a long time to search through all of them for this code.
I have the xml code shown below. Everything is working as it should except the final textView( id locationTextView) which won't stay right. I want it to stay as right as possible, but I can't do that(it still appears straight after the linear Layout).Should I set a left margin?. And for the textView1 how can I make it to show only a certain part of the whole text, because I have texts of different lengths and they ruin the layout.

I have two buttons on home screen A & B. On clicking either of them, respective forms should appear in the same screen. I am not able to show the forms without launching a new screen.
I have a problem with the android:background tag, which I am only able to use once, while I need more than once feature for my TextViews. More details below:
I have 3 TextView:

shown here:
The TextView border is obtained with this file, back.xml, included in res/drawable folder:

android:shape="rectangle" >
<!--<solid android:color="#ffffff" />-->
<stroke android:width="1dip" android:color="#4fa5d5"/>
</shape>
Since I am already using the background tag to input the back.xml file and create a rectangular border for the TextViews, I don't know how to use it for my other needs, which are:
As far as I know I can only do this with the tag background, which is already used to get the back.xml drawable.
How can I fulfill my needs?
I'm doing an Android App in which I take a photo with camera, then there is A Gallery (of the photos), under an ImageView (the photo in format of Bitmap), and textviews in which I say name of photo (date), and position (latitude and longitude, with GPS). Obviously, if I click in an Image of the gallery, it'll appear in full screen! My problems are: 1. How to connect gallery with ImageViews (bitmap) by Camera. 2. How do I "save" the gallery? (Maybe with Hashmap, but I don't know what's that!)...Please don't make complicated codes cause this isn't an advanced android exam! Sorry for my terrible english!! This is my code:`
