Android常见的五种动画

							***

旋转、平移、缩放、透明度、组合
AnimationSet setAnimation = new AnimationSet(true);
// 特别说明以下情况
// 因为在下面的旋转动画设置了无限循环(RepeatCount = INFINITE)
// 所以动画不会结束，而是无限循环
// 所以组合动画的下面两行设置是无效的， 以后设置的为准
setAnimation.setRepeatMode(Animation.RESTART);
setAnimation.setRepeatCount(1);// 设置了循环一次,但无效

// 旋转动画
Animation rotate = new RotateAnimation(0,360,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);
rotate.setDuration(1000);
rotate.setRepeatMode(Animation.RESTART);
rotate.setRepeatCount(Animation.INFINITE);

// 平移动画
Animation translate = new TranslateAnimation(TranslateAnimation.RELATIVE_TO_PARENT,-0.5f,
        TranslateAnimation.RELATIVE_TO_PARENT,0.5f,
        TranslateAnimation.RELATIVE_TO_SELF,0
        ,TranslateAnimation.RELATIVE_TO_SELF,0);
translate.setDuration(10000);

// 透明度动画
Animation alpha = new AlphaAnimation(1,0);
alpha.setDuration(3000);
alpha.setStartOffset(7000);

// 缩放动画
Animation scale1 = new ScaleAnimation(1,0.5f,1,0.5f,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);
scale1.setDuration(1000);
scale1.setStartOffset(4000);

// 将创建的子动画添加到组合动画里
setAnimation.addAnimation(alpha);
setAnimation.addAnimation(rotate);
setAnimation.addAnimation(translate);
setAnimation.addAnimation(scale1);
// 使用
mButton.startAnimation(setAnimation);
