安卓：记时计与毫秒？ [英] Android: Chronometer with Miliseconds?

问题描述

我要的是测量时间与毫秒为单位，但使用天文台都有它没有精确度的问题（其最分辨率为秒） 我已经看到了这一点： 显示毫秒与Android天文台 但我没有能够使它发挥作用。也许我应该用另外一个对象？你知道吗？

What I want is to measure time with miliseconds, but using Chronometer has the problem that it has no accuracy (its most resolution is seconds) I've seen this: Show miliseconds with Android Chronometer But I haven't been able to make it work. Maybe I should use another Object? Any idea?

推荐答案

好吧，这是最简单的方法：当你要开始计时：

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，你只需要做当前时间与开始时间比较：

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.

和这样你就可以milis（它是否到达我想要的时间？这是多少计时？...）

And so you can play with milis (Has it arrive to the time I wanted? How many time is it counting? ...)
