Question

我有一些问题将Android AlarmManager设置为每天执行。用户可以设置他的特定时间，并且应该每天运行。这是代码：

@Override
protected void onResume() {
    super.onResume();

    Intent intent = new Intent(MainActivity.this,
            NotificationBroadcastReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getService(
            MainActivity.this, 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);

    // Make sure, there is no active Alarm
    alarmManager.cancel(pendingIntent);

    if(notificationEnabled) {
        Calendar cal = Calendar.getInstance();
        cal.set(Calendar.AM_PM, Calendar.PM);

        cal.set(Calendar.HOUR_OF_DAY, notificationHour);
        cal.set(Calendar.MINUTE, notificationMinute);
        cal.set(Calendar.SECOND, 0);


        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                cal.getTimeInMillis(), AlarmManager.INTERVAL_DAY,
                pendingIntent);
    }

}

现在我无法弄清楚，为什么这不会起作用。我曾经将警报设置为10:05，警报在晚上开启。警报应该在特定时间每天开启（如果它当然只启用）。从当天开始。因此，如果我将其设置为几分钟或几小时后，它应该在今天和每隔一天运行，直到我取消警报。＃

我认为你从日历中获得了一个错误的Unix时间戳。试试这个

// Set the alarm to start at approximately 2:00 p.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 14);

// With setInexactRepeating(), you have to use one of the AlarmManager interval
// constants--in this case, AlarmManager.INTERVAL_DAY.
alarmMgr.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
        AlarmManager.INTERVAL_DAY, alarmIntent);
