The best way to explain something is an example

So this is the showcase how one can populate a RecyclerView with different types of items:

• No switch-case inside an RecyclerView.Adapter.
• No RecyclerView.Adapter delegates for each view type.
• Single RecyclerView.Adapter class that suits all items in the application.
• Forces you to separate business models from UI models.
• Still can provide more than just 1:1 mapping via a custom RecyclerView.ViewHolder. See a nested RecyclerView in the example.
