Question

我正在尝试在新的通知中启动计时器，但是从暂停的（经过的）“经过的时间从另一个计时器得到”，而不是从零开始

计时器通知[HttpPost] [ValidateAntiForgeryToken] public async Task<ActionResult> Create(Exam exam) { ... }中的起始base与RemoteViews.class中的起始基数不同，它有不同的计算

Chronometer.class

我得到Notification notification = new NotificationCompat.Builder(getApplicationContext()) .setSmallIcon(R.mipmap.ic_launcher) .setContentTitle(songName).build(); notification.contentView = simpleContentView;

timeWhenPaused

然后创建long timeWhenPaused = myChronometer.getBase() - SystemClock.elapsedRealtime();

chronometer

从零开始

Answer 1

我尝试了很多计算方法，最终得到了这个。

notification.contentView.setChronometer(R.id.chronometer_recorder
                            , (SystemClock.elapsedRealtime() + timeWhenPaused)
                            , null
                            , true
                    );

然后

long elapsedMillis = SystemClock.elapsedRealtime() - myChronometer.getBase();

Answer 2

我希望这会有所帮助>>>> 我使用远程视图的计时器示例（在通知中）。

long startTime = SystemClock.elapsedRealtime();

Calendar endTime = Calendar.getInstance();  // time in future
         endTime.set(Calendar.HOUR_OF_DAY, YOUR_HOUR);
         endTime.set(Calendar.MINUTE, YOUR_MINUTE);
         endTime.set(Calendar.SECOND, 0);

Date now = new Date();
long elapsed = now.getTime() - endTime.getTimeInMillis();
long remainingTime = startTime - elapsed;

        remoteViews.setChronometerCountDown(R.id.chronometer, true);
        remoteViews.setChronometer(R.id.chronometer, remainingTime, ("%tH:%tM:%tS"), true);

计时器从Notification RemoteViews中的特定值开始
