Creating a game in Android using multiple ImageButtons to display an image from the drawable folder and I want to change the button to a different image after the button has been clicked on. Here is the code for my image button:

 <ImageButton 
android:id="@+id/b56"
 android:layout_width="45px"
 android:layout_height="45px"
 android:layout_gravity="center_vertical"
 android:src="@drawable/black" 
 /> 

I can't find anything about how to change the actual image of the button. You can change the color of the button by using the following code in the java file:

b32.setBackgroundColor(0xAA00AA00);
