推荐答案

使用CountDownTimer类，通过一个巨大的价值（在这里我给10亿）的CountDownTimer生活。

Use CountDownTimer class , pass a huge value to (here I gave 1000000000) for CountDownTimer life .

样品code ::

CountDownTimer newtimer = new CountDownTimer(1000000000, 1000) { 

            public void onTick(long millisUntilFinished) {
                Calendar c = Calendar.getInstance();
                textView.setText(c.get(Calendar.HOUR)+":"+c.get(Calendar.MINUTE)+":"+c.get(Calendar.SECOND));
            }
            public void onFinish() {

            }
        };
        newtimer.start();

在关闭活动，请拨打以下函数

While closing the Activity, call the following function

newtimer.cancel();
