Animation动画

Animation:  1，AlphaAnimation, 透明度动画，

                   2， RotateAnimation, 旋转动画，

                   3，ScaleAnimation, 缩放动画

                   4，TranslateAnimation 位移动画

              通过setDuration（）设置动画时长，setAnimation（）将想要的动画添加到你所想要的图片ImageView上。

note：如果想让一张图片具有多个动画的话，使用AnimationSet动画集合类，用addAnimation()添加想要的动画。
