title: Update RecyclerView in Fragment from MainActivity
body: <p>I have a TabLayout with a Fragment containing a RecyclerView. In the MainActivity I have a Toolbar which had the option to remove an item from the RecyclerView. I want this to happen with a remove animation (so I need to call notifyItemRemoved()) and therefore I think I cannot simply update the data-set that is passed to the RecyclerView and then reinflate the fragment. Does anyone know a way to achieve this (what code to implement in the onClick method in my MainActivity and what code in my Fragment/RecyclerViewAdapter)?</p>
