title: In Android, how to change the title of a different MenuItem inside onOptionsItemSelected()
body: <p>On clicking a certain MenuItem in a Options Menu in Android, I need to change the title of a different MenuItem in the same Menu. What is the way to do this?</p>
  
  <p>When a MenuItem in an options menu is clicked, onOptionsItemSelected(MenuItem menuitem) is called.
  You can change the title of the MenuItem which is passed as a parameter in the 
  onOptionsItemSelected(MenuItem menuitem), but not of any other MenuItem. I need to know how to change the title of a MenuItem that is not passed as parameter to onOptionsItemSelected(), but which belongs to the same Menu.</p>
  
  <p>I did not find a way to get handle to containing Menu inside the onOptionsItemSelected method (which is called when any MenuItem is clicked).</p>
  
  <p>Many Thanks.</p>
