How to get selected item of a singlechoice Alert Dialog?

Question

I have this code to show a dialog with singlechoice(radio) options.

AlertDialog ad = new AlertDialog.Builder(this)
.setCancelable(false)
.setIcon(R.drawable.alert_dialog_icon)
.setTitle(R.string.choose_one)
.setSingleChoiceItems(seq, pos,null)
.setPositiveButton( R.string.ok, new DialogInterface.OnClickListener() { 
  public void onClick( DialogInterface dialog, int whichButton) 
  { 
    // dialog dismissed
  } 
 }).create();

How do I get the choice that has been selected?

Answer 1

I believe that you use an OnClickListener for setSingleChoiceItems(), to listen whenever an item has been selected; then once the user hits okay, you set that item in stone. Right now you're just passing null, so nothing you can't pick up which item was selected.
