Use FrameLayout for the following

<FrameLayout 
android:id="@+id/button1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/image1"
>

<Button
android:id="@+id/button2"
android:layout_gravity="center"
android:src="@drawable/image2" />

</FrameLayout>
