Reusable Custom Components

Have you ever extended a View class? If not, this session is for you.

We will start from a simple example of enhancing the TextView class, and finish with a complete custom view with its own size measurement, drawing function and custom attributes. We will also discuss the best practices for custom views. What is the different between a custom view and a fragment? How about a compound control? When to use which?

By the end of the session, you will know not only how to create reusable custom components, but when to use them.

Users should have successfully developed an end-to-end app beyond "Hello World" and tutorials prior to taking this session.
