If you use ActionBarSherlock
, you can use the triangle ABS uses:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
etc />
<ImageView
android:layout_width="32dp"
android:layout_height="32dp"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:contentDescription="@string/expand_triangle"
android:src="@drawable/abs__spinner_ab_default_holo_light" />
</RelativeLayout>
