计时器从 Notification RemoteViews 中的特定值开始

Question

我正在尝试在新通知中启动计时器，但从暂停（已过）"the elapsed time is got from another chronometer"，而不是从零开始

计时器通知 RemoteViews.class 中的开始 base 与 Chronometer.class 中的开始基地不同，它有不同的计算

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

然后我得到 timeWhenPaused

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

然后创建 chronometer

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

从零开始

Answer 1

我试了很多方法计算终于搞定了

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

然后

notification.contentView.setChronometer(R.id.chronometer_recorder_notification
                    ,(SystemClock.elapsedRealtime() - elapsedMillis ^5)
                    ,null
                    ,true
            );

希望对您有所帮助>>> 我使用远程视图的计时器的工作示例（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);
