Answer 1

You can implement an OnItemclicklistener and then react to Itemclicks. Use this method to change the source of the bitmap then.

It works now with the above method. here is the code.

 @Override
        public void onItemClick(AdapterView<?> adaptview, View clickedview, int position,
                long id) {

            //TEST SO 4533684
            View subview = clickedview.findViewById(R.id.bgimageCoverLetter);
            ((ImageView) subview).setImageResource(R.drawable.icon);
            //END TEST 
        }
