2.5. Layout, views, and widgets

A special resource known as a layout is what you’ll use to design screens, items for lists, and other UI elements in Android. We introduced layouts in chapter 1, but here we’ll clarify how you declare them as XML, and we’ll touch on the components that comprise them: views and widgets.

We won’t be done with layout, views, and widgets with one short discussion here, but we’ll add detail as we keep the focus on the basics of Android development. Then, in chapter 4 we’ll come back to these topics and take the deep dive.
