title: Create a RecyclerView(Grid Layout manger) inside a CardView
body: <p>I am trying to make a custom favorites screen for my dialer app <img src="https://i.stack.imgur.com/QhRXq.png" alt="this"></p>
  
  <p>I can do the following:</p>
  
  <ul>
  <li>GridView inside a cardView enclosed by a recyclerview(with linearLayoutManager)</li>
  <li>Recycler view(with a gridLayoutManager) inside a cardView enclosed by a recyclerView(with LinearLayoutManager)</li>
  </ul>
  
  <p>The card's height should be dynamic i.e change with the number of items.Also all items(photos) are clickable.
  Can anyone tell me which approach is better?</p>
