About

Android Views are composed as a hierarchy with a single root View which usually has many children Views inside of it. These Views are declared inside of an XML file, called a layout file or layout. Often, to support modularity and code reuse, you'll end up breaking parts of the layout into children layouts. In the case of Data Binding, this means you'll need a way to pass variables that you define in the parent layout, down to it's children. This lesson will teach you how to do that.

Key concepts in this lesson that you will learn:
* How to pass a Data Binding View Variable from a parent layout down, to a child layout.
* How to make use of Android Studio's quick assist features to convert existing layouts to use Data Binding.
* Best practice for naming consistency of variables across the parent and child layout.
