Android and setContentView?
<p>I have one activity, off this I have two classes.</p>

<p>When my app starts I setContentView to a layout that is in one of my classes.</p>

<p>Now inside this layout there is a button which needs to setContentView to the layout that is in my other class.</p>

<p>How can I change the content view? How can my subclass send a message back to my main class to tell it to change the setContentView?</p>
