Android Animation无限循环动画

方法一： 
①参考：http://blog.csdn.net/jiangwei0910410003/article/details/16985999 
②anim中主要参数设置

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">  
    <alpha  
        android:fromAlpha="0.0"  
        android:toAlpha="1.0"  
        android:duration="1000"
        android:repeatCount="infinite"
        android:repeatMode="restart"/>  
</set>

 方法二： 

①Animation设置setAnimationListener(new ReStartAnimationListener()) 
②ReStartAnimationListener()具体实现

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">  
    <alpha  
        android:fromAlpha="0.0"  
        android:toAlpha="1.0"  
        android:duration="1000"/>  
    <alpha
        android:startOffset="3000"
        android:fromAlpha="1.0"  
        android:toAlpha="0.0"  
        android:duration="1000"/>
</set>

/**
     * 重复启动动画
     */
    private class ReStartAnimationListener implements Animation.AnimationListener {

        public void onAnimationEnd(Animation animation) {
            // TODO Auto-generated method stub
            animation.reset();
            animation.setAnimationListener(new ReStartAnimationListener());
            animation.start();
        }

        public void onAnimationRepeat(Animation animation) {
            // TODO Auto-generated method stub

        }

        public void onAnimationStart(Animation animation) {
            // TODO Auto-generated method stub

        }

    }
