仿网易云音乐 专辑图片折叠轮播

先不多说现上一张效果图

首先简述一下实现原理

1.首先让我们的imageview**动起来**

其实是不断的.invalidate();函数 让他不断的调用ondarw函数 
（显然我们不必要不断的调用ondarw函数 只有在我们让他动的时候调用即可 所以我们要声明一个变量记录change记录是否产生动画）

2.实现我们的可折叠效果

Matrix的setPolyToPoly方法的使用 
可参考（http://blog.csdn.net/lmj623565791/article/details/44278417）

3.实现图片一上一下的来回切换

paint.setXfermode(xfermode); xfermode就是如何处理两张图片的重叠效果 共有16种处理方式

实现自定义imageview

属性

存放bitmap的list 
动画间隔的变量 
动画桢间隔的变量 
两个handler用于发送消息 
前景与背景的索引

代码
