title: Imageview parallax as you scroll
body: <p>I saw many examples demonstrative parallax background as you scroll or listview parallax but I cannot find a clear example how to implement a parallax effect on images as you scroll in the activity.</p>
  
  <p>An example implementation can be found in Airbnb app. As you scroll down you can see more of the image's bottom and as you scroll up you can see more of the image's top.</p>
  
  <p>Any hints and tips on how to create such effect?</p>
