Use this in your Activity

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {



    if(keyCode==KeyEvent.KEYCODE_DPAD_DOWN)
    {
        //your code
 return false;
    }
    if(keyCode==KeyEvent.KEYCODE_DPAD_CENTER)
    {
          /*yourcode*/                                          

return false;
    }
    if(keyCode==KeyEvent.KEYCODE_DPAD_LEFT)
    {
        //your code                                         
return false;
    }
    if(keyCode==KeyEvent.KEYCODE_DPAD_RIGHT)
    {
        //your code                                         
return false;
    }
    if(keyCode==KeyEvent.KEYCODE_DPAD_UP)
    {
        //your code                                         
return false;
    }
    return super.onKeyDown(keyCode, event);
}

Edited code

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {

    if(keyCode==KeyEvent.KeyEvent.KEYCODE_DPAD_CENTER)
    {
        Toast.makeText(<Activity_name>.this, "Application Quits", Toast.LENGTH_SHORT).show();
          finish();
          return false;
    }

    return super.onKeyDown(keyCode, event);
}
