<Buttonandroid:layout_width="match_parent"android:layout_height="match_parent"android:background="@drawable/hover"

Solution 4:

Hovering is possible on Android: all devices that have a track ball or D-pad or QWERTY keyboard arrow keys can move the "hover" or focus to anything that is pressable (clickable). Then, on my G1 for example, you press the track ball to press it down into the android:state_pressed state.
