How to get selected item of a singlechoice Alert Dialog?

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)
