title: how to put a border around an android relativelayout?
body: <p>I've seen this  <a href="https://stackoverflow.com/questions/3182723/android-draw-custom-border-around-listview">subject</a> about puting a border around an android textview, and I used it. But now, I would like to put a border around widgets which are situated into a relative layout. How can I do it?</p>
