title: RadioGroup OnCheckedChangeListener()
body: <p>Using a radiogroup to display a number of options on the UI. Currently using OnCheckedChangeListener() to detect an event on the radiogroup. The problem is OnCheckedChangeListener() only fires when a radiobutton other than the currently active radiobutton is selected. </p>
  
  <p>I also want to trigger an event when the currently active radiobutton is selected.</p>
  
  <p>I've tried onClick() on the radiogroup and radiobutton but no success...</p>
  
  <p>Tips? Ideas? Workaround?</p>
