Android 使ObjectAnimator动画持续时间独立于“开发人员选项”中的“全局动画持续时间比例”设置

方法。我注意到没有明确的答案。您可以通过反射调用隐藏的API来实现这一点:
// Get duration scale from the global settings.
float durationScale = Settings.Global.getFloat(context.getContentResolver(),
Settings.Global.ANIMATOR_DURATION_SCALE, 0);
// If global duration scale is not 1 (default), try to override it
// for the current application.
if (durationScale != 1) {
try {
ValueAnimator.class.getMethod("setDurationScale", float.class).invoke(null, 1f);
durationScale = 1f;
} catch (Throwable t) {
// It means something bad happened, and animations are still
// altered by the global settings. You should warn the user and
// exit application.
}
}
有关更多详细信息,请查看此博文:如果不想弄乱setDurationScale,请执行此操作
//in activity, kotlin
val animScale = Settings.Global.getFloat(this.contentResolver, Settings.Global.ANIMATOR_DURATION_SCALE, 1f)
animator.setDuration((timeInMs/animScale).toLong())
你是怎么做到的?你可以发布一些帮助的例子。这并不能完全解决这个问题,因为用户可以关闭动画,将比例设置为0。这样就会失败。
