Solution 1:

I just made a simple program which toggles the light filter on and off.

Here is the Activity:

ButtonbuttonClicked=null;
     @OverridepublicvoidonCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
     }

     publicvoidclickedButton(View v) {
         Buttonbutton= (Button)v;
         button.getBackground().setColorFilter(newLightingColorFilter(0xFFFFFFFF,
                                                                       0x66FF33));

         if (buttonClicked != null) {
             buttonClicked.getBackground().setColorFilter(null);
         }
         buttonClicked = button;

     }

and here is the XML
