res/drawable/my_multi_state_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:state_pressed="true"
android:drawable="@drawable/some_png" />
<item android:state_focused="false" android:state_pressed="true"
android:drawable="@drawable/some_png" />
<item android:drawable="@drawable/other_bg" />
</selector>

Point to that as in android:background="@drawable/my_multi_state_bg"
or through java code wherever u please.
