WHAT YOU WILL LEARN IN THIS CHAPTER
- What the various ViewGroups are that you can use to lay out your views
- How to use the basic views in Android to design your user interface

In Chapter 2, you learned about the Activity and Fragment classes and their life cycles. You learned that an activity (as well as a fragment) is a means by which users interact with the application. However, an activity or fragment by itself does not have a presence on the screen. Instead, it has to draw the screen using Views and ViewGroups. In this chapter, you learn the details about creating user interfaces in Android, and how users interact with them.
