title: Android RadioButton dynamic icon change
body: <p>I'm doing a multiple choice quiz app. It has 4 <code>radio buttons</code>. What I want to have is have 3 icons -> No answer yet, right answer, wrong answer. So before any choice is clicked, all are non-answer, when an answer is clicked, if it is right, it light up green, if wrong - light up red. Is it possible to do with radio buttons? Or do I have to find another way out? Like using an <code>ImageView</code>?</p>
