title: CoordinatorLayout + AppBarLayout + NavigationDrawer
body: <p>I have a layouting problem when combining <code>CoordinatorLayout</code> with an <code>AppBarLayout</code> and a <code>NavigationDrawer</code>. </p>
  
  <p>The problem is, that the NavigationDrawer and it's content are hidden behind the toolbar. I have already did a lot of research and tried a lot of restructuring, but none of the "solutions" fixed my issue.</p>
  
  <p>A demonstration can be found in this little Webm video: <a href="https://www.dropbox.com/s/i5zfc2x2ts2fws7/navigation_drawer_stackoverflow32523188.webm?dl=0" rel="noreferrer">https://www.dropbox.com/s/i5zfc2x2ts2fws7/navigation_drawer_stackoverflow32523188.webm?dl=0</a></p>
  
  <p>The base style is <code>Theme.AppCompat.Light.NoActionBar</code>.</p>
  
  <p>My <strong>activity_overview.xml</strong> looks like this:</p>
