FrameLayout buttons overlap, and can't be 'touched. - what's right way to access?
<p>I'm using a FrameLayout and have two buttons on it, button A and button B (in addition to some other widgets).  A is directly on top of B, overlapping completely.</p>

<p>In onCreate, I do a check and if A is not needed, I set it to invisible.  Later in the app it may become visible again so I don't want to remove it completely.</p>

<p>When button B is pressed, it doesn't respond.  I think button A is stopping the press even though it's invisible.  Other buttons do respond so this is why I think this.</p>

<p>Is there a common way to make it so B accepts touches?  Do I have to remove A?  I don't really want to remove A as I have a relative layout in the frame layout and other controls depend on A for positioning.</p>
