title: How to hide and show a menu in BottomNavigationView?
body: <p>I have created an activity with BottomNavigationView and it is working fine.</p>
  
  <p>But I am unable to hide a menu item.</p>
  
  <p>I have tried this code.</p>
  
  <p>bottomNavigationView.getMenu().findItem(R.id.tab_email).setVisible(false);</p>
