The Android framework has a large set of
View classes for
interacting with the user and displaying various
types of data. But
sometimes your app has unique needs that aren’t covered by the built-in views. This class shows you
how to create your
own views that are robust and reusable.
- Creating a View Class
- Create a class that acts like a built-in view, with custom attributes and support from the ADT layout editor.
- Custom Drawing
- Make your view visually distinctive using the Android graphics system.
- Users expect a view to react smoothly and naturally to input gestures. This lesson discusses how to use gesture detection, physics, and animation to give your user interface a professional feel.
- No matter how beautiful your UI is, users won't love it if it doesn't run at a consistently high frame rate. Learn how to avoid common performance problems, and how to use hardware acceleration to make your custom drawings run faster.
