title: How do Android's new Toolbar and the Contextual Action Bar work together?
body: <p>I'm redesigning my current app roughly following Chris Bane's <a href="https://chris.banes.me/2014/10/17/appcompat-v21/" rel="nofollow noreferrer">excellent intro here</a>. One thing struck me, though:</p>
  
  <p>If I set the new v7-appcompat <code>Toolbar</code> as actionbar replacement via <code>setSupportActionBar()</code> and derive my theme from <code>Theme.AppCompat.Light.NoActionBar</code>, then the contextual action bar (CAB) will still pop up and push my contents, including the Toolbar, down:</p>

  <p>Now, I could try to make the CAB overlay my Toolbar, but I figured the UI (basically the metrics and placement) of the back button and text of the CAB don't match the Toolbar either (as seen in the image), so I wonder if there is rather a "CAB" mode in the Toolbar implementation so that the Toolbar could take over this role as well?</p>
