Answer 1

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.

Here is xml-- hover.xml --

<item android:drawable="@drawable/image__hover" android:state_focused="false" android:state_pressed="true"/>
<item android:drawable="@drawable/normalimage"/>

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

You need to use what's called a selector.

You can read about them and get a tutorial from this site.

Keep in mind that there really isn't a concept in Android as "hover" since you can't hover your finger over the display. But you can create selectors for, say, when a button has focus. Normally a button can have three states: Normal, Focused and Pressed.
