title: NavigationView menu items with counter on the right
body: <p>The new <strong>NavigationView</strong> in the new <strong>Design Support Library</strong> works really great.</p>
  
  <p>They use "<strong>menu-items</strong>" to display the options.</p>
  
  <p>But how can I display a <strong>counter</strong> to the <strong>right</strong> of the menu item?</p>
  
  <p><strong>Like in this picture:</strong></p>

  <p>Or like in the <strong>GMail</strong> app.</p>
