title: How to add notification badge on Bottom Navigation View?
body: <pre><code>&lt;item
          android:id="@+id/nav_gallery"
          app:actionViewClass="android.widget.TextView"/&gt;
  </code></pre>
  
  <p>This is the menu of bottom Navigation.</p>
  
  <pre><code>   TextView gallery=(TextView)  
     MenuItemCompat.getActionView(navigationView.getMenu().
     findItem(R.id.nav_gallery)); //getting menu item of bottom nav view
     gallery.setText("99+");
  </code></pre>
  
  <p>But this code doesnot work for bottom navigation view.BottomNavigationView is shown without setting any notification counter.</p>
