android animation 动画

之前写DOME，动画后按钮的点击事件无法触发，所以本文主要是解决UI移动后点击事件的触发。至于动画的属性很多地方都有，下面简单介绍下

四种基本动画：

           JAVA代码                            XML文件

1、AlphaAnimation        ——   alpha（透明度）

2、ScaleAnimation        ——   scale（缩放）

3、TranslateAnimation  ——   translate（移动）

4、RotateAnimation       ——   rotate（旋转）

注：用xml创建动画在项目中建立res/anim目录来存放文件

        在代码中通过AnimationUtils.loadAnimation(context,R.anim);的静态方法调用。

上代码：
