title: Have an item overlap the actionbar?
body: <p>I am using the new <code>CoordinatorLayout</code>, <code>AppBarLayout</code> and <code>Toolbar</code> classes. I'm trying to have an image overlap the action bar. You can see in the screenshot that the actionbar is pulled down half of the screen and that the content view (an image in this case) overlaps it. Is this possible to do? </p>

  <p>I've tried using a FrameLayout but it doesn't seem to work.</p>
