如何在 android 中停止 CountDownTimer

Question

如何停止这个计时器，知道吗？

我想在每个查询中重置计时器，但它仍在继续。每个新查询都会添加新的计时器。如何解决？

 new CountDownTimer(zaman, 1000) {                     //geriye sayma

            public void onTick(long millisUntilFinished) {

                NumberFormat f = new DecimalFormat("00");
                long hour = (millisUntilFinished / 3600000) % 24;
                long min = (millisUntilFinished / 60000) % 60;
                long sec = (millisUntilFinished / 1000) % 60;

                cMeter.setText(f.format(hour) + ":" + f.format(min) + ":" + f.format(sec));
            }

            public void onFinish() {
                cMeter.setText("00:00:00");
            }
        }.start();

Answer 1

您可以将其分配给一个变量，然后在该变量上调用cancel()

CountDownTimer yourCountDownTimer = new CountDownTimer(zaman, 1000) {                    
    public void onTick(long millisUntilFinished) {}

    public void onFinish() {}

    }.start();

yourCountDownTimer.cancel();

或者您可以在计数器范围内调用 cancel()

new CountDownTimer(zaman, 1000) {                    
    public void onTick(long millisUntilFinished) {
        cancel();
    }

    public void onFinish() {}

    }.start();

Answer 2

您可以在其回调方法之一中调用 this.cancel() 或简单地调用 cancel()

Answer 3

static CountDownTimer countDownTimer = null;

    if (countDownTimer != null) {
        countDownTimer.cancel();
    }
    countDownTimer = new CountDownTimer(50000, 1000) {
        public void onTick(long millisUntilFinished) {
            Log.e("seconds remaining : ", "seconds remaining : " + millisUntilFinished / 1000);
        }

        public void onFinish() {
            Log.e("done!", "done!");
        }
    };
    countDownTimer.start();
