title: Android: How to set the selection in a single choice AlertDialog?
body: <p>I created a single choice AlertDialog with "Apply" and "Cancel" buttons. When the user presses "Cancel", I would like to set the selected item back to what it was when the dialog was first shown (I have the value stored already).</p>
  
  <p>I know how to set the selected item when the dialog is first created in <code>setSingleChoiceItems()</code> but is there a way to set it again later?</p>
  
  <p>I would like to be compatible with API level 7, so I'd rather not use <code>onPrepareDialog()</code>.</p>
