android 动画集合执行完发现会闪烁一下

Question

如题 写了个慢慢出现的动画集合
代码如下：
visibleSet = new AnimationSet(true);

    ScaleAnimation scaleAnimation = new ScaleAnimation(0.5f, 1f, 0.5f, 1f, 0.5f, 1f);
    scaleAnimation.setDuration(500);

    TranslateAnimation translateAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 1f, Animation.RELATIVE_TO_SELF, 0f,
            Animation.RELATIVE_TO_SELF, 1f, Animation.RELATIVE_TO_SELF, 0f);
    translateAnimation.setDuration(500);

    AlphaAnimation alphaAnimation = new AlphaAnimation(0, 1);
    alphaAnimation.setRepeatCount(1);
    alphaAnimation.setDuration(500);

    visibleSet.addAnimation(scaleAnimation);
    visibleSet.addAnimation(alphaAnimation);
    visibleSet.addAnimation(translateAnimation);

    visibleSet.setDuration(500); 
            麻烦技术大牛看看哪里的问题
