I also ran into this situation and figured out how to do it using FrameLayout. The following output is produced by the code given below.
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/contactbook_icon"
android:layout_gravity="center" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="140"
android:textSize="12dp"
android:textColor="#FFFFFF"
android:layout_gravity="bottom|right"
android:layout_margin="15dp" />
</FrameLayout>
Change the margin value to adjust the text position over the image. Removing margin might make the text to go out of the view sometimes.
