Summary

In this chapter, we learned how to add RecyclerView support to our project. We also learned how to add RecyclerView to our layout and how to populate it with items. We went through adding different item types, which is particularly useful for titles. We covered interaction with RecyclerView, responding to clicks on individual items and responding to swipe gestures.

Lastly, we learned how to dynamically add and remove items to and from RecyclerView. The world of RecyclerView is very rich, and we have only scratched the surface.
