Apps ImageButton, onkeydown and picture?

[Grendizer]

Hi all,

I have a Dialpad in which there are multiple buttons. Whenever a button is clicked a sounds plays and the background of the imagebutton is changed.
For this I'm using

ImageButton zero = (ImageButton) findViewById(R.id.btnZero);
        zero.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                playSound(R.raw.mamacita_zero);
            }
        });

And the XML for the button is as follows:

<?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/green0" /> <!-- pressed -->        
        
     <item 
         android:drawable="@drawable/blue0" /> <!-- default -->
     
 </selector>

I also have an onKeyDown(...) method for playing the sound, but I'm not able to get the imagebutton to switch background on the click...So my question is how to change the imagebutton's background when the onkeydown method is used?
Any tips would be appreciated...

OnKeyDown Listener should be called properly as in this example Android Codes: Example code for OnKeyDown listener in Android
