【中文标题】计时器从 Notification RemoteViews 中的特定值开始

【英文标题】：Chronometer start from specific value in Notification RemoteViews

【问题描述】：

我正在尝试在新通知中启动计时器，但从暂停（经过）“经过的时间来自另一个计时器”，而不是从零开始

时计的NotificationRemoteViews.class中的起始base与Chronometer.class中的起始基准不同，计算不同

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

我得到了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

【参考方案1】：

我尝试了很多计算方法终于得到了这个。

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

然后

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

【参考方案2】：

希望对你有帮助>>>> 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);
