title: How to swipe images
body: <p>I am trying to implement a simple gallery of images in which I have an image to be displayed at a time on the device screen. When we swipe the screen from left to right it should show the next image.<br>
  For that I implemented a view flipper and added image views to it.<br>
  But I don't know how to catch that swipe event.<br>
  Can anyone tell me with an example?</p>
