使用优先级设置设置多个警报，但是优先级较低的警报不会关闭

Question

所以我想创建一个提醒应用程序，每个提醒都有自己的优先级（在我的情况下：1 =最重要，2 =不太重要，3 =最不重要）。并且我检索时间以将警报设置为Long纪元时间，并将优先级值设置为String，并且当有多个提醒同时存在但优先级不同时，我会以较低的优先级来更改提醒的时间用这种方法：

public void setPriority(){
    for (int i = 0; i < aLongDateTime.size(); i++){
        Long temp = aLongDateTime.get(i);
        for (int j = i + 1; j < aLongDateTime.size(); j++) {
            if (temp.equals(aLongDateTime.get(j))) {
                switch (aPriority.get(i)) {
                    case "1":
                        if (!aPriority.get(j).equals(aPriority.get(i))) {
                            aLongDateTime.set(j, aLongDateTime.get(j)+150000);
                        }
                        break;
                    case "2":
                        if (aPriority.get(j).equals(aPriority.get(i)) && (!aPriority.get(j).equals("1"))) {
                            aLongDateTime.set(j, aLongDateTime.get(j)+150000);
                        }
                        break;
                    case "3":
                        if (aPriority.get(j).equals(aPriority.get(i)) && (!aPriority.get(j).equals("1")) && (!aPriority.get(j).equals("2"))) {
                            aLongDateTime.set(j, aLongDateTime.get(j)+150000);
                        }
                        break;
                }
            }
        }

        for (int j = i + 1; j < aLongDateTime.size(); j++) {//in case there are three or more reminders with same time
            if (temp.equals(aLongDateTime.get(j))) {
                if (aPriority.get(i).equals("2") && !aPriority.get(j).equals("1") && !aPriority.get(j).equals(aPriority.get(i))) {
                    aLongDateTime.set(j, aLongDateTime.get(j)+150000);
                } else if (aPriority.get(i).equals("3") && !aPriority.get(j).equals("1") && !aPriority.get(j).equals("2") && aPriority.get(j).equals("3")) {
                    aLongDateTime.set(j, aLongDateTime.get(j)+150000);
                }
            }
        }
    }
}

然后使用此设置警报：

private void startAlarm(long LTime) {
    alarmManagers = new AlarmManager[20];

    br = new BroadcastReceiver() {
        (My OnReceive method)
    };

    for (int i = 0; i < remtasklist.size() ; i++) {
        registerReceiver(br, new IntentFilter("com.my.project.app"));
        PendingIntent pendingIntent = PendingIntent.getBroadcast(this, i, new Intent("com.my.project.app"), PendingIntent.FLAG_UPDATE_CURRENT);
        alarmManagers[i] = (AlarmManager) getSystemService(ALARM_SERVICE);
        if (alarmManagers[i] != null) {
            alarmManagers[i].set(AlarmManager.RTC_WAKEUP, LTime, pendingIntent);

        }
        pendingIntents.add(pendingIntent);
    }
}

问题在于，当同时有两个提醒（或两个以上）时，第一个提醒关闭，而第二个提醒却没有。
