title: Android: Change ActionBar Menu Items from Fragment
body: <p>Can anyone give a quick example of how to change the contents of an Activity action bar based on something that takes place in a fragment?  My intent:</p>
  
  <p>Normal menu items -> Something in the fragment is moved -> menu items change to save / discard buttons.</p>
  
  <p>My first impulse is to setup Broadcast Receivers in both the activity and the fragment to cross talk, but I am not sure if this is correct.</p>
