How do I make a picture seem like a radiobutton?
<p>I am attempting to use my own buttons to make an overlay at the bottom of the screen. When a button is pressed it should light up (kind of how a radio button turns green when selected) and it should take you to a new activity while keeping the overlay intact. </p>

<p>There are five buttons that should be put on a black bar and when selected it should turn blue. </p>

<p>If someone could send me in the right direction I would be very grateful. Thank you</p>
