警报管理器不会每天触发

Question

在我的项目中，我需要安排一个任务在每天的特定时间显示通知。如果我今天将它设置为某个时间，它会触发并且一切都会按预期进行，但如果计划时间是明天，它不会触发。下面是我设置警报管理器的代码。

public void setMorningRepeatingTask(Context context, int hour, int minutes) {
        alarmMgr = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(context, AlarmBroadcastReceiver.class);
        intent.setAction(Constants.ALARM_MANAGER_INTENT_MORNING_UNIQUE_ACTION);
        alarmIntent = PendingIntent.getBroadcast(context, Constants.MORNING_ALARM_UNIQUE_ID, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, hour);
        calendar.set(Calendar.MINUTE, minutes);
        if(checkIfTheTimeHasPassed(calendar.getTimeInMillis())){
            calendar.add(Calendar.DATE, 1);
        }
        alarmMgr.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
                AlarmManager.INTERVAL_DAY, alarmIntent);
        FileLogger.writeToFile("Alarm Set", "Morning repeating Alarm Set");
    }

public static boolean checkIfTheTimeHasPassed(long timeInMillis) {
        long nowTime = new Date().getTime();
        return nowTime > timeInMillis;
    }

请帮忙。

我终于找到了解决我面临的问题的方法。我使用 alarmMgr.set() 方法而不是 alarmMgr.setRepeating() 并且当闹钟响起时我为第二天设置了另一个闹钟。就这样，日复一日地重复着。 :)

我仍然想知道 alarmMgr.setRepeating() 方法有什么问题。所以，如果有人有任何想法，请 post 解决方案。

下面是我实现的代码。

public void setMorningRepeatingTask(Context context, int hour, int minutes, boolean forceScheduleNextDay) {
        alarmMgr = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
        Intent intent = new Intent(context, AlarmBroadcastReceiver.class);
        intent.putExtra(Constants.KEY_ALARM_TIME, Constants.VALUE_MORNING_ALARM);
        alarmIntent = PendingIntent.getBroadcast(context, Constants.MORNING_ALARM_UNIQUE_ID, intent,
                PendingIntent.FLAG_UPDATE_CURRENT);
        Calendar calendar = Calendar.getInstance();
        calendar.set(Calendar.HOUR_OF_DAY, hour);
        calendar.set(Calendar.MINUTE, minutes);
        if (Utility.checkIfTheTimeHasPassed(calendar.getTimeInMillis()) || forceScheduleNextDay) {
            calendar.add(Calendar.DATE, 1);
        }
        alarmMgr.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), alarmIntent);
        Log.i("Morning Alarm", "Alarm is set for " + calendar.get(Calendar.DATE) + " at "
                + calendar.get(Calendar.HOUR_OF_DAY) + ":" + calendar.get(Calendar.MINUTE));
        FileLogger.writeToFile("Alarm Set", "Morning repeating Alarm Set");
        FileLogger.writeToFile("Morning Alarm", "Alarm is set for " + calendar.get(Calendar.DATE) + " at "
                + calendar.get(Calendar.HOUR_OF_DAY) + ":" + calendar.get(Calendar.MINUTE));
    }

以上方法用于设置闹钟

if (Utility.checkIfTheTimeHasPassed(calendar.getTimeInMillis()) {
   calendar.add(Calendar.DATE, 1);
}

public static boolean checkIfTheTimeHasPassed(long timeInMillis) {
    long nowTime = new Date().getTime();
    return nowTime > timeInMillis;
}

以上条件会检查时间是否已经过去，如果已经过去，则会安排第二天的闹钟。

当触发警报时，将调用BroadcastReceiver子类的onReceive()方法。

@Override
 public void onReceive(Context context, Intent intent) {
    FileLogger.writeToFile("Alarms rang off!!", "Alarm rang");

    //Add your logic here

    setMorningRepeatingTask(context,morningTimeCalender.get(Calendar.HOUR_OF_DAY), morningTimeCalender.get(Calendar.MINUTE), true);
}

在这个方法中，在闹钟上做了我想做的事情后，我用同样的方法重新安排了第二天的闹钟。
