The Note to Self app

Despite all we have learned, we are not quite ready to apply a solution to the Note to Self app. We could update our code to store lots of notes in an ArrayList, but before we do, we also need a way to display the contents of our ArrayList in the UI. It won't look good to throw the whole thing into a TextView.

The solution is Adapters, and a special UI layout called RecyclerView. We will get to them in the next chapter.
