我有以下AnimatorSet方法：

private AnimatorSet dialCenterThrob() {

int bpm = workoutStream.getHeartRate();

dialCenterImageView.clearAnimation();

AnimatorSet finalSet = new AnimatorSet();

ObjectAnimator pulseX = ObjectAnimator.ofFloat(dialCenterImageView, View.SCALE_X, 0.98f, 1.06f);

ObjectAnimator pulseY = ObjectAnimator.ofFloat(dialCenterImageView, View.SCALE_Y, 0.98f, 1.06f);

pulseX.setRepeatMode(ObjectAnimator.REVERSE);

pulseX.setRepeatCount(ObjectAnimator.INFINITE);

pulseY.setRepeatMode(ObjectAnimator.REVERSE);

pulseY.setRepeatCount(ObjectAnimator.INFINITE);

pulseX.setDuration(bpm);

pulseY.setDuration(bpm);

pulseX.setInterpolator(new AccelerateInterpolator());

pulseY.setInterpolator(new AccelerateInterpolator());

finalSet.playTogether(pulseX, pulseY);

return finalSet;

}

这是在var上设置的,称为throbber,偶尔会通过以下方法更新：

private void updateThrobbing() {

if (hasThrob()) {

throbber = dialCenterThrob();

throbber.start();

} else {

if (throbber != null && throbber.isRunning()) {

stopThrobbing();

}

}

}

但我不能让它停止动画,这是目前尝试这样做的方法：

public void stopThrobbing() {

List throbbers = throbber.getChildAnimations();

for(Animator animator : throbbers) {

//accomplishes nothing

((ObjectAnimator)animator).setRepeatCount(0);

((ObjectAnimator)animator).setRepeatMode(0);

}

throbber.pause(); //nothing

throbber.cancel(); //and again, nothing

throbber.end();//shocking, I know, but really, nothing

throbber = null;//you'd think this would definitely do it, but no

//desparate attempt, in vein, of course

dialCenterImageView.clearAnimation();

}

我不能让它停止动画.更新：我只是尝试将本地ref存储到单个对象动画师,然后调用setRepeatCount,mode,pause,end,取消每个,但仍然没有.
