Question

我在Android中实现了老虎机。卷轴是ScrollViews，LinearLayouts作为子项，单个图块作为ImageViews垂直定位在LinearLayout内部。我使用ObjectAnimator滚动到ScrollView的末尾，使用ValueAnimator.RESTART和ValueAnimator.INFINITE。卷轴滚动很好而且流畅，但是当它重复时，它会暂停一秒钟，这会破坏效果。以下是我使用的代码：

  public void spinReel(SlotReel reel) {
        final int reelSize = this.context.getPixelsInDPs(64);
        final SlotMachineView me = this;
        final SlotReel myReel = reel;
        ImageView[] tiles = reel.getTiles();
        int delta = tiles.length - reel.currentTileNumber();
        ObjectAnimator animator = ObjectAnimator.ofInt(reel, "scrollY", tiles.length * reelSize );
        animator.setInterpolator(new LinearInterpolator());
        animator.setDuration(delta * 75);
        animator.setStartDelay(0);
        animator.setRepeatMode(ValueAnimator.RESTART);
        animator.setRepeatCount(ValueAnimator.INFINITE);
        animator.addListener(new Animator.AnimatorListener() {
            @Override
            public void onAnimationStart(Animator animator) {

            }

            @Override
            public void onAnimationEnd(Animator animator) {
            }

            @Override
            public void onAnimationCancel(Animator animator) {

            }

            @Override
            public void onAnimationRepeat(Animator animator) {
                myReel.scrollTo(0, reelSize * 3);

            }
        });
        animator.start();

    }

请注意，无论是否将scrollTo置于Repeat回调中，都会出现急动。

你应该尝试：

number of lines for lable = 0

看这里 Android ValueAnimator pauses during repeat

Android中循环动画的ScrollView在重复之间暂停
