Android documentation说你可以设置刷新率:
Frame refresh delay: You can specify how often to refresh frames of your animation. The default is set to refresh every 10 ms, but the speed in which your application can refresh frames is ultimately dependent on how busy the system is overall and how fast the system can service the underlying timer.
但是，它并没有告诉您如何操作。到处找遍了，在ObjectAnimator、PropertyAnimator、Animator中都没有这个方法。
编辑:我目前使用的是每 5 帧仅响应一次的动画更新程序 -
colorFade.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
int interpolator = 0;
@Override
public void onAnimationUpdate(ValueAnimator animation) {
if ((interpolator++) % 5 == 0)
invalidate(mHandlerBounds);
}
});
最佳答案
正如@pskink 所说，使用:
public static void setFrameDelay(long frameDelay)
属于 ValueAnimator类(class)。你可以在文档中看到这个:
The amount of time, in milliseconds, between each frame of the animation. This is a requested time that the animation will attempt to honor, but the actual delay between frames may be different, depending on system load and capabilities. This is a static function because the same delay will be applied to all animations, since they are all run off of a single timing loop. The frame delay may be ignored when the animation system uses an external timing source, such as the display refresh rate (vsync), to govern animations.
