Android 很炫的拖动效果(源码)

先来看效果图:



就两个文件，新建一个项目把下面两个文件放进去，设置好启动activity就行了

FlingGallery.java

// TODO: 
// 1. In order to improve performance Cache screen bitmap and use for animation 
// 2. Establish superfluous memory allocations and delay or replace with reused objects 
// Probably need to make sure we are not allocating objects (strings, etc.) in loops
