there is a RelativeLayout in it there are several checkboxes with answers, you need to select one or more answers, then press the check button and after pressing the button one icon should appear opposite the correct answer and another icon opposite the wrong one!
The question is, how can you display an icon on a RelativeLayout ?

Answer 1

And what is the actual problem?
Throw icons in front of the checkboxes, make them invisible, and when they answer, make them visible, or simply do not initially load the picture, but load the visible one after the
upd response
view.setVisibility
(View.VISIBLE);
invisible
view.setVisibility(View.INVISIBLE);
or
view.setVisibility(View.GONE);
