Question

我有一个alarmManager，每天上午9点重复一次调用服务。我希望每天上午9点（重复）触发警报，服务A，中午服务B，下午4点服务C.

我目前这样做的方法是每3小时重复一次并获取服务中的当前时间，并根据时间确定应该触发哪个动作，但这感觉过于苛刻。这是我的代码。我希望我可以实例化多个AlarmManager实例，但我怀疑我能否给它初始化的方式。

        Intent i_notifcreate = new Intent(this, NotifCreator.class);
        PendingIntent pi_notifcreator = PendingIntent.getService(this, 0, i_notifcreate, PendingIntent.FLAG_UPDATE_CURRENT);
        AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(System.currentTimeMillis());
        calendar.set(Calendar.HOUR_OF_DAY, 9);
        calendar.set(Calendar.MINUTE, 00);
        Log.e("NextAlarm", calendar.getTime().toString());
        alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_HOUR, pi_notifcreator);

服务中的pseduocode

if(time == 9AM){
   A()
} else if (time == noon){
   B()
} ... etc

我能够使用这个标题不明确的问题alarmmanager 2 times

来解决这个问题

Calendar cal1 = Calendar.getInstance();
cal1.set(Calendar.HOUR_OF_DAY, 05);
cal1.set(Calendar.MINUTE, 45);
cal1.set(Calendar.SECOND, 00);

Calendar cal2 = Calendar.getInstance();
cal2.set(Calendar.HOUR_OF_DAY, 17);
cal2.set(Calendar.MINUTE, 30);
cal2.set(Calendar.SECOND, 00);

// Test if the times are in the past, if they are add one day
Calendar now = Calendar.getInstance();
if(now.after(cal1))
    cal1.add(Calendar.HOUR_OF_DAY, 24);
if(now.after(cal2))
    cal2.add(Calendar.HOUR_OF_DAY, 24);

// Create two different PendingIntents, they MUST have different requestCodes
Intent intent = new Intent(this, AlarmReceiver.class);
PendingIntent morningAlarm = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, 0);
PendingIntent eveningAlarm = PendingIntent.getBroadcast(getApplicationContext(), 1, intent, 0);

// Start both alarms, set to repeat once every day
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal1.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, morningAlarm);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, cal2.getTimeInMillis(), DateUtils.DAY_IN_MILLIS, eveningAlarm);

AlarmManager setRepeating for Multiple Instances
