Answer 1

That is because imgButton is null. Try this instead:

findViewById(R.id.imgButton).setBackgroundResource(R.drawable.ic_action_search);

imgButton = (Button) findViewById(R.id.imgButton);
imgButton.setOnClickListener(imgButtonHandler);

then in onClick: imgButton.setBackgroundResource(R.drawable.ic_action_search);
