Get selected menu item's index value in the navigation drawer
<p>I have implemented navigation drawer, it is working fine. The only problem that I have to make selected item to deselect when the navigationdrawer closes. I wonder how could I able to get the index value of selected menu item.</p>

<pre><code>navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
  @Override
  public boolean onNavigationItemSelected(MenuItem menuItem) {
      menuItem.setChecked(false);
   }
)}
</code></pre>
