Android ValueAnimator动画无法使用API​​ 19

我正在使用OUSHENG x8 mini pro，API 19（4.4.2）测试我的应用程序。

特别是我面临的问题是使用几个ValueAnimator对象动画的ProgressBar的行为：

private AnimatorSet animatorSet;
private ValueAnimator R2LAnimation;
private ValueAnimator L2RAnimation;
public ValueAnimator getL2RAnimation(final ProgressBar progressBar) {
    ValueAnimator valueAnimator = ValueAnimator.ofInt(0, progressBar.getMax());
    valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            int value = (Integer) animation.getAnimatedValue();
            LogUtils.traceD(LOG_TAG, "Animation Progress Value: " + value);
            progressBar.setProgress(value);
        }
    });
    return valueAnimator;
}

public ValueAnimator getR2LAnimation(final ProgressBar progressBar) {
    ValueAnimator valueAnimator = ValueAnimator.ofInt(progressBar.getMax(), 0);
    valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
        @Override
        public void onAnimationUpdate(ValueAnimator animation) {
            int value = (Integer) animation.getAnimatedValue();
            LogUtils.traceD(LOG_TAG, "Animation Progress Value: " + value);
            progressBar.setProgress(value);
        }
    });
    return valueAnimator;
}

这是我的日志输出：

...

（这种情况一直持续下去）

唯一写入的值是0和1000，中间没有“灰色区域”。

我的应用程序表现得还不错，有了更新的API（22,23,24,25）：

...

与Drawable的另一个ValueAnimator动画（ofAlpha（））完全相同的事情：不在API 19上工作，在其他的上工作正常。

为什么会这样？
