如何保持CountDownTimer运行时，我preSS后退按钮 [英] How keep a CountDownTimer running when I press the back button

问题描述

我有一个CountDownTimer它更新一个TextView，但是当我preSS后退按钮停止。

I have a CountDownTimer which updates a TextView, but when I press the back button it stops.

CountDownTimer timer = new CountDownTimer(600000, 100) {

    public void onTick(long millisUntilFinished) {
        calendar.setTimeInMillis(millisUntilFinished);

        cron.setText(sf.format(calendar.getTime()));
    }

    public void onFinish() {
    }
};

我怎样才能保持它运行的时候我preSS后退按钮和活性被破坏？

How can I keep it running when I press the back button and the activity gets destroyed?

PS：我也启动了GPS服务时，计时器开始，有没有办法把CountDownTimer在服务

PS: I also start a GPS service when the timer starts, Is there a way to put the CountDownTimer in the service?

推荐答案

如果您的计时器需要生活超越你的活动的生命周期，那么它不属于那里。你当然可以把它放到一个服务或其他对象（如单身），可以在内存中驻留。

If your timer needs to live beyond the lifecycle of your Activity, then it does not belong there. You can certainly place it into a Service, or another object (like a singleton) that can stay resident in memory.
