title: what event listener to add to radio button when page is swiped in Android?
body: <p><img src="https://i.stack.imgur.com/kD1Dz.png" alt="pageController"></p>
  
  <p>I am working on a page controller application. My logic involves placing custom radio buttons at the bottom of one page.</p>
  
  <p>I would like to create a listener on the radio button when the user swipes the page to move to the next. I am not aware exactly how to do this. I have attached an image to relay my idea.</p>
  
  <p>Any thoughts would be greatly appreciated.</p>
  
  <p>Thanks in advance.</p>
