title: Horizontal Recyclerview with scrollable header
body: <p>I want to implement an android horizontal recyclerview like the image shown below.<a href="https://i.stack.imgur.com/pR9nU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/pR9nU.png" alt="Both week block and day block needs to be scrolled at the same time"></a></p>
  
  <p>Both week block and day block needs to be scrolled at the same time. After day 14 another week have to come. So to make both blocks scroll at the same time I imagine it needs to be in the same recyclerview. I have implemented the day recyclerview. But I don't know how to implement the week block. Week block needs to be of the 7-day block size. How do I do that?</p>
