title: fitSystemWindows is never being called
body: <p>I've got a view that needs to be anchored to the bottom of the screen. In fullscreen it needs to be at the very bottom, but during temporary non-fullscreen (on user taps) it needs to move up to not be hidden by the system bar. The docs say that setting android:fitsSystemWindows=true should do the trick. Or you could even override fitSystemWindows to get the new bounds and apply the margin yourself.</p>
  
  <p>The problem is that this method is never called, so the property doesn't work either and there doesn't seem to be anything I can do. It looks like fitSystemWindows on ActionBarOverlayLayout is the culprit: it's returning true from it's method at all times, which seems to then be canceling the propagation of that method to any other views in the tree. But, that's a system class and it doesn't look like there much I can do to get it to stop doing that apart from possibly removing the actionbar completely.</p>
  
  <p>I know I have to be missing something. Can only one view ever be set to avoid being trampled by the system components? This is just a video player, and I've seen plenty of other video players that don't seem to have this problem. Thanks for any help!</p>
