Android 设置动画 也会启动动画么？？？

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);"></span><pre name="code" class="java"> private void initFloatAbAnim() {        Logger.e("fooo init anim");        /* 差速器 */        AccelerateDecelerateInterpolator accelerateDecelerateInterpolator = new AccelerateDecelerateInterpolator(); // 先加速后减速        // 根据各自的构造方法来初始化一个实例对象        mAnimationAlpha = new AlphaAnimation(0.1f, 1.0f);        mAnimationAlpha.setDuration(500);        mAnimationAlpha.setInterpolator(accelerateDecelerateInterpolator);        mAnimationScale = new ScaleAnimation(0.0f, 1.0f, 0.0f, 1.0f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);        mAnimationScale.setDuration(500);        mAnimationScale.setInterpolator(accelerateDecelerateInterpolator);        // mFloatAb.setAnimation(myAnimation_Alpha);        // mFloatAb.setAnimation(myAnimation_Scale);        mAnimationAlpha.setAnimationListener(new AnimationListener() {            @Override            public void onAnimationStart(Animation animation) {                mFloatAb.setVisibility(View.VISIBLE);            }            @Override            public void onAnimationRepeat(Animation animation) {                // TODO Auto-generated method stub            }            @Override            public void onAnimationEnd(Animation animation) {                // TODO Auto-generated method stub                // mFloatAb.setVisibility(View.VISIBLE);            }        });        mAnimationSet = new AnimationSet(false);        mAnimationSet.addAnimation(mAnimationAlpha);        mAnimationSet.addAnimation(mAnimationScale);        //set animation 也会启动动画么?                //mFloatAb.setAnimation(mAnimationSet);    }

设置过动画， 也会启动动画效果么？？？

实验是这样的。。。
