title: RecyclerView - Keep selected position after adding new elements
body: <p>The question is plain simple: As I add new elements to the adapter to the beginning of the adapter's list, how can I keep the RecyclerView with the same position selected?</p>
  
  <p>I've been playing with the scrolling methods but I can't find the right solution. </p>
  
  <p>Thank you</p>
