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?

I know this is an old post, but i just came across it, and found that this solution seems at bit more simple that whats been posted here.

You can just do like this:

In your onClick() handler on the dialog positive button, add the following code:

ListView lw = ((AlertDialog)dialog).getListView();
Object checkedItem = lw.getAdapter().getItem(lw.getCheckedItemPosition());

Note that if you haven't selected any option it will crash you have to add a check here before getting the checkedItem with if(lw.getCheckedItemCount() > 0)
