title: setting z order of View with bringChildToFront()
body: <p>I'm trying to set the z order of a UI element (i.e. a View) so that it will overlap another element, but calling ViewGroup.bringChildToFront() has a weird side effect....it moves the element to be the last item in the parent (the ViewGroup).  Is this a bug, expected behavior, or what?  More importantly, how can I set the z order or a View without this unfortunate side effect?</p>
