title: Floating Action Button not moving up and down
body: <p><strong>Problem:</strong> I have implemented a <code>FloatingActionButton</code> and I followed the sample of Androidhive. But when the <code>SnackBar</code> is shown the <code>FloatingActionButton</code> does not move up.</p>
  
  <p><strong>Question:</strong> How can I achieve that the <code>FloatingActionButton</code> will move up and down if the <code>SnackBar</code> appears?</p>
