title: Passing changing variables to RecyclerView Adapter
body: <p>I have a custom <code>RecyclerView.Adapter</code> that is used to render the layout of my list. In the parent Activity I have two variables that can be changed from the UI. These parameters are used to render part of the RecyclerView item. </p>
  
  <p>I know I can pass some data via the Adapter constructor, but this is a one time thing. How can I pass data to the Adapter and change it on the fly?</p>
