Question

我已经看到这个问题在搜索时弹出了几次，但似乎没有解决我的问题。我的倒数计时器在一个服务中运行并且工作得很好，除了它在到达onFinish（）之前有一个延迟。它将在完成（）上进行5,4,3,2,1（长暂停）。然而，这个问题;当我在我的设备上使用android studio的调试器模式时不会发生。当设备未连接到调试器时，我的应用程序会遇到延迟。有没有办法在使用倒数计时器时删除修复问题？我看到的其他解决方案涉及使用处理程序或可运行程序，但我更喜欢用倒数计时器说。下面的代码包含服务中的倒数计时器。我感谢任何帮助。

服务代码

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    if (intent != null) {
        if (startService) {
            startService = false;
            data = intent.getIntExtra("the", 0);
            // int progress = data/1000;
            // CountDownAct.timeProgressBar.setMax(progress);
            //
            // CountDownAct.timeProgressBar.setProgress(1000);
            countDownTimer = new CountDownTime(data, 1000);
            countDownTimer.start();

            // timer = new Timer();
            // IntentFilter filter = new IntentFilter();
            // filter.addAction(ALARM_SERVICE);
            // registerReceiver(timer, filter);

        }
    }
}

public class CountDownTime extends CountDownTimer {

    /**
     * @param millisInFuture
     *            The number of millis in the future from the call to
     *            {@link #start()} until the countdown is done and
     *            {@link #onFinish()} is called.
     * @param countDownInterval
     *            The interval along the way to receive
     *            {@link #onTick(long)} callbacks.
     */
    public CountDownTime(long millisInFuture, long countDownInterval) {
        super(millisInFuture, countDownInterval);
    }

    @Override
    public void onTick(long millisUntilFinished) {
        long millis = millisUntilFinished;

        int progress = (int) (millisUntilFinished / 1000);
        // this is the format which reads the time data from the user and
        // makes it readable
        hms = String.format("%02d:%02d:%02d", TimeUnit.MILLISECONDS.toHours(millis), TimeUnit.MILLISECONDS.toMinutes(millis) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millis)),
                TimeUnit.MILLISECONDS.toSeconds(millis) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millis)));

        CountDownAct.timeTextView.setText(hms);
        CountDownAct.timeProgressBar.setProgress(progress);
        Log.i("CountDownService", hms);

    }

    @Override
    public void onFinish() {
        CountDownAct.timeProgressBar.setProgress(0);
        Intent goBack = new Intent(getApplicationContext(), alarmtimefinished.class);

        goBack.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        goBack.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
        startActivity(goBack);
        // CountDownService.startService = true;
        //
    }

}

Answer 1

试了一下，非常奇怪..呃，我不确定这是不是真的是一个'答案'，但是解决方案就是忘记onFinish并创建自己的onfinish with like（millisUntilFinished / 1000 == 1）{// ..做任何事情}

Answer 2

尝试用100而不是1000

来调用计时器

countDownTimer = new CountDownTime(data, 100);

倒数计时器延迟
