问题描述
我想要的是以毫秒为单位测量时间，但是使用Chronometer却存在精度不高的问题(其最高分辨率为秒)我已经看到了:使用Android Chronometer显示毫秒但是我无法使其工作.也许我应该使用另一个对象?有什么主意吗?
What I want is to measure time with milliseconds, but using Chronometer has the problem that it has no accuracy (its most resolution is seconds)I've seen this:Show miliseconds with Android ChronometerBut I haven't been able to make it work. Maybe I should use another Object? Any idea?
推荐答案
好，这是最简单的方法:当您要启动计时功能时:
Ok, this is the easiest way: When you want to start the chrono:
StartTime=System.currentTimeMillis(); // I've defined StartTime as a double
然后，您只需要将当前时间与StartTime进行比较:
Then, you just have to do compare current time with StartTime:
millis=System.currentTimeMillis()-StartTime; // Millis is a double too
// If you'd want seconds, add seconds=(int) milis/1000; etc.
这样您就可以玩milis(到达我想要的时间了吗?它要数多少时间?...)
And so you can play with milis (Has it arrive to the time I wanted? How many time is it counting? ...)
