title: How to keep an alertdialog open after button onclick is fired?
body: <p>The subject kinda says it all.. I'm requesting a PIN code from the user, if they enter it, click the OK Positive Button and the PIN is incorrect I want to display a Toast but keep the dialog open. At the moment it closes automatically..  Sure this is very trivial thing to correct but can't find the answer yet.</p>
  
  <p>Thanks..</p>
