Lesson

(1)创建一个View类

Create a class that acts like a built-in view, with custom attributes and support from the ADT layout editor.

(2)自定义Drawing

Make your view visually distinctive using the Android graphics system.

(3)使得View是可交互的

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.

(4)优化View

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.
