You need to make that resource be a StateListDrawable.

The easiest way to do this is to copy the XML for the standard Button
StateListDrawable. You can find this in:

$ANDROID_HOME/platforms/$VERSION/data/res/drawable/btn_default.xml

(where $ANDROID_HOME is where you installed the SDK and $VERSION is one
of the SDK versions)

Change that to point to your own nine-patch images for your various
button backgrounds (normal, pressed, selected).
