title: How to handle Back button with in the dialog?
body: <p>I am developing an application that when the button is pressed, it opens a dialog with OK and Cancel buttons.</p>
  
  <p>It works fine.</p>
  
  <p>When the user presses the back button, I am handling this as follows</p>
  
  <pre><code>public boolean onKeyDown(int keyCode, KeyEvent event) 
  {
      if ((keyCode == KeyEvent.KEYCODE_BACK)) 
      {
  
      }
   return super.onKeyDown(keyCode, event);
  }
  </code></pre>
  
  <p>But the above method is not called. How can I handle this?</p>
