I want to pause chronometer and after I click the button I want to continue chromoneter to count... I search but couldn't a function related this.. how can do it?

推荐答案

您是要去需要，保持跟踪已经过去了，因为该天文台开始的时间变量：

You are gonna need a variable that keeps track on the time that has passed since the Chronometer was started:

long timeWhenStopped = 0;

当你停止计时表这样的更新变量的值：

Update the value of the variable when you stop the chronometer like this:

timeWhenStopped = mChronometer.getBase() - SystemClock.elapsedRealtime();
mChronometer.stop();

我们也将使用这个变量开始前调整记时计：

We will also use this variable to adjust the chronometer before starting it:

mChronometer.setBase(SystemClock.elapsedRealtime() + timeWhenStopped);
mChronometer.start();

最后，如果你有办法重置您的天文台表，那么你应该记得也重置timeWhenStopped变量。事情是这样的：

And finally if you have a way to reset your chronometer then you should remember to also reset the timeWhenStopped variable. Something like this:

mChronometer.setBase(SystemClock.elapsedRealtime());
timeWhenStopped = 0;
