title: Contextual action bar for edit activity
body: <p>I have a question regarding the concept of contextual action bar. The Android Design Guide suggests to use the CAB when the user selects something in an Activity to offer him some actions.</p>
  
  <p>As implemented in the "People"(/"Contacts"?) application, it also makes sense to edit data.
  For example, I want the user to click a list item which brings him to a details activity. In the details activity you can press on an edit action item that brings you to the edit activity. In this edit activity I want to show the CAB to allow saving by pressing the DONE button or BACK button or cancel via a menu item.</p>
  
  <p>Is the CAB intended to be used in this way? It´s implemented in the People app like this, so I think yes.</p>
  
  <p>My current implementation starts the action mode on activity creation. This is somehow uncool, because when pressing DONE, I start an AsyncTask to save the data on the server, which needs time, but the CAB is gone immediatelly and then the default action bar is shown. Is there a nicer way to use the CAB, so that it gets destroyed not before the activity?</p>
  
  <p>PS: using ActionBarSherlock</p>
