When they added RecyclerView they knew this so they added this pattern right into it, so it is a part of RecyclerView instead of having to be added on the way it was when using a Listview

The example on the Android dev site shows the inner class as static https://developer.android.com/training/material/lists-cards.html As I understand in Java you can only put the static keyword on an inner class. By putting the static keyword on the the inner class it removes that implicit reference you had to the outer containing class. So I would assume it is just a design decision, encapsulate things properly and the like
