title: View which turns into a header view on Scroll (Gmail and Google +)
body: <p>I would like to recreate this behaviour in my app. Gmail and Google + have it in common. </p>
  
  <p>Its a view that turns into a header view when scrolling through the body of information.</p>
  
  <p>It is not a fixed view as seen in the image on the left, it becomes fixed after the user has started scrolling through.</p>
  
  <p>Has anyone done this before or could anyone recommend a way of doing this.</p>
  
  <p>Thanks</p>
  
  <p>Here's an image:</p>
