title: How to use notifyDataSetChanged with the new NavigationView?
body: <p>I use the new <code>NavigationView</code> in one of my recent projects. However I have a problem for the update data.</p>
  
  <p>Previously, I used a <code>ListView</code> in my <code>DrawerLayout</code> and when I needed to change my data I called <code>notifyDataSetChanged()</code> method of my Adapter.</p>
  
  <p>Currently <code>NavigationView</code> does not <code>notifyDataSetChanged()</code> method and when I want to update an item on my menu nothing is happening, for example:</p>
  
  <pre><code> Menu menuAccount = navigationView.getMenu().findItem(R.id.drawer_item_account).getSubMenu();
   menuAccount.findItem(R.id.drawer_item_login).setVisible(!isLoggedIn);
  </code></pre>
  
  <p>Do you have a solution ? Thanks you for your help.</p>
