Here is the answer.

To indicate the different button states (focused, selected, etc.), you can define a different image for each state

Save the XML file in your project res/drawable/ folder and then reference it as a drawable for the source of your ImageButton (in the android:src attribute). Android will automatically change the image based on the state of the button and the corresponding images defined in the XML.

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_pressed="true"
       android:drawable="@drawable/button_pressed" /> <!-- pressed -->
   <item android:state_focused="true"
       android:drawable="@drawable/button_focused" /> <!-- focused -->
   <item android:drawable="@drawable/button_normal" /> <!-- default -->
</selector>
