title: How can i start the action mode of a MultiChoiceModeListener from a ListView
body: <p>I've implemented a contextual action bar(CAB) with multiple selection in a listview. (similar to <a href="https://stackoverflow.com/a/10598553/940637">https://stackoverflow.com/a/10598553/940637</a>).</p>
  
  <p>Now i would to implement a editbutton, which needs to trigger the CAB to be shown. Is there anyway how this can be done?</p>
  
  <p>I've tried startActionMode (but than i need to implement a separate callback), which i don't like.</p>
