Chapter 4. Lists and Adapters

Even in the simplest connected application, there is a list of things to be displayed. There is a list of items, users, locations, or for example, things to do. This is not the case always, but we can assume that a high percentage of applications show these items. Even in offline-only applications, there are many things to be shown as a list. In this chapter, we will focus on how to display lists using a ListView element. We'll see how to do this efficiently using a RecyclerView element and how to change and update the data shown on these lists by using adapters. We will end the chapter by introducing a more complex structure that will allow us to display a list in a more complex way, such as some well-known applications such as Pinterest or Etsy.
