How to prevent android form from skipping sections in form?

I have an Android form consisting of some editText and spinner widgets. When you start with the first edittext and hit "next" on the on-screen keyboard, it skips the spinners and goes straight to the next edittext input. How can I prevent skipping entries regardless of what type of entries they are? i.e., spinner, edittext, dialog, etc. Here's my layout:

<ScrollView xmlns:android="http://ift.tt/nIICcg"
android:id="@+id/ScrollView01" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:scrollbars="vertical"
android:background="@drawable/flagbackground" >
<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="490dp"
    android:gravity="center"
    android:orientation="vertical" >

<TextView android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/vetn"
    android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText android:id="@+id/etVetName"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:inputType="text" />
<TextView android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/vetdob"
    android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText android:id="@+id/etVetDob"
    android:layout_width="fill_parent"
