在Android中稳定，准确地计时 [英] Steady, accurate timing in Android

问题描述

我正在尝试为Android设备创建音乐音序器应用，希望能获得一些有关如何实现可靠的计时功能的建议.

I'm trying to create a music sequencer app for Android devices and would appreciate some advice as to how to achieve rock-solid timing functionality.

如果我将Runnable传递给Handler.postDelayed并指定x毫秒的延迟时间，那么Runnable是否保证在正好x毫秒的时间内执行?

If I pass a Runnable to Handler.postDelayed and specify a delay time of x milliseconds, is that Runnable guaranteed to be executed in exactly x ms time?

如果使用Handler无法获得稳定而准确的计时，还有什么其他选择可供我选择?

If I can't achieve steady and accurate timing with Handler, what other options are open to me?

提前谢谢

处理程序，Thread.sleep()和计时器似乎不是解决之道.

Handlers, Thread.sleep() and timers are not the way to go it seems.
