All icons of ActionMode Bar are not showing in Android?

I have created a menu for my actionmode bar with icons but not all menu are showing with icon in actionmode bar. This is my menu xml file.

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://ift.tt/nIICcg"
xmlns:app="http://ift.tt/GEGVYd">
<item
    android:id="@+id/menu_archive"
    android:icon="@drawable/ic_action_file_archive"
    android:orderInCategory="100"
    android:title="@string/action_remove"
    app:showAsAction="always" />
<item
    android:id="@+id/menu_upload_to_cloud"
    android:icon="@drawable/ic_action_file_cloud_upload"
    android:orderInCategory="200"
    android:title="@string/action_upload_to_cloud"
    app:showAsAction="always" />
<item
    android:id="@+id/menu_delete"
    android:icon="@drawable/ic_action_file_delete"
    android:orderInCategory="300"
    android:title="@string/action_move_to_trash"
    app:showAsAction="always" />
</menu>

This is my code for creating Actionmode Bar.

    @Override
public boolean onCreateActionMode(android.support.v7.view.ActionMode mode, Menu menu) {
    MenuInflater inflater = mode.getMenuInflater();
    inflater.inflate(R.menu.menu_actionmode_device_documents, menu);
    return true;
}

@Override
public boolean onPrepareActionMode(android.support.v7.view.ActionMode mode, Menu menu) {
    return false;
}

@Override
public boolean onActionItemClicked(android.support.v7.view.ActionMode mode, MenuItem item) {

}

@Override
public void onDestroyActionMode(android.support.v7.view.ActionMode mode) {
    this.actionMode = null;
}

This image is my output which is showing only one icon of menu but i want all other icons too.
