每条记录多个特定时间推送通知问题

Question

我正在开发家庭药房应用程序，每个用户都有多个成员，这意味着(所有家庭成员都有一个应用程序)，所以我有一个用户表和成员表，药品表和member_drugs表。

成员表有列：

id，user_id，name，age，...etc...

member_drugs表包含以下各列：

id，member_id，drug_id，drug dose，drug dose repetition (即一天中第一次和第二次注射之间的时间间隔--可能是6小时)，first time dose，等等……

现在我需要推送每个剂量提醒的通知(在其特定时间内的所有重复)。

例如：

成员y的药物x，药物剂量重复是3小时，药物的第一次是上午12点，所以:我需要推送通知: 1-第一次在：12 am。以及以下内容中的重复：

2- 3 am。

3- 6 am。

4- 9 am。

5- ....等等。

我的问题是通知只是第一次出现。

我在这段代码中尝试过，但它不起作用。我不知道我错过了什么

这是我的通知服务方法：

@Override
    protected void onHandleWork(Intent intent) {

        Date date = new Date();
        toda = dateFormat.format(date);
        today = dateFormat.parse(toda, new ParsePosition(0));

        java.util.Date date1 = new java.util.Date();
        String current = sdf.format(date1);

        Date now1 = sdf.parse(current, new ParsePosition(0));
        String now = sdf.format(now1);
        arrayList1 = setTimeAlarm();
        if (arrayList1 != null) {
            if (arrayList1.size() > 0) {
                for (DrugAlert d : arrayList1) {
                    Log.d(getClass().getSimpleName(), "heeeeeeeeeeeeer");

                    String start = d.get_start_date();
                    Date d1 = dateFormat.parse(start, new ParsePosition(0));
                    String end = d.get_end_date();
                    Date d2 = dateFormat.parse(end, new ParsePosition(0));
                    String firstTime = d.getAlert_time();
                    Date t1 = sdf.parse(firstTime, new ParsePosition(0));
                    String t = sdf.format(t1);
                    int repeat = d.getDose_r();

                    Calendar cal = Calendar.getInstance(); // creates calendar
                    cal.setTime(t1); // sets calendar time/date

                    if ((d2.after(today) || d2.equals(today)) && (d1.equals(today) || today.after(d1))) {
                            for (int i = repeat; i<=24; i = i +repeat){
                               // i = repeat;
                                cal.add(Calendar.HOUR_OF_DAY,i); // adds one hour if repeat == 1
                                cal.getTime(); // returns new date object, one hour in the future
                                Date repDose1 = cal.getTime();
                                String repDose = sdf.format(repDose1);
                                if (t.equals(now) || repDose.equals(now) ) {
                                    memName = d.getMember_name();
                                    drugName = d.getDrug_name();
                                    courseId = d.get__id();
                                    dose = d.getDose_q();
                                    Log.d(getClass().getSimpleName(), "onHandleIntent, started handling a notification event");
                                    try {
                                        processStartNotification();
                                        NOTIFICATION_ID = NOTIFICATION_ID +1;
                                        String action = intent.getAction();
                                        if (ACTION_START.equals(action)) {
                                            processStartNotification();
                                        }
                                    } finally {
                                        WakefulBroadcastReceiver.completeWakefulIntent(intent);

                                    }
                                }
                            }



                    }
                }
            }
        }


    }

我通过以下代码修复：

 @Override
    protected void onHandleWork(Intent intent) {

        Date date = new Date();
        toda = dateFormat.format(date);
        today = dateFormat.parse(toda, new ParsePosition(0));

        java.util.Date date1 = new java.util.Date();
        String current = sdf.format(date1);

        Date now1 = sdf.parse(current, new ParsePosition(0));
        String now = sdf.format(now1);
        arrayList1 = setTimeAlarm();
        if (arrayList1 != null) {
            if (arrayList1.size() > 0) {
                for (DrugAlert d : arrayList1) {
                    Log.d(getClass().getSimpleName(), "heeeeeeeeeeeeer");

                    String start = d.get_start_date();
                    Date d1 = dateFormat.parse(start, new ParsePosition(0));

                    Date d2 = dateFormat.parse(end, new ParsePosition(0));
                    String firstTime = d.getAlert_time();
                    Date t1 = sdf.parse(firstTime, new ParsePosition(0));
                    String t = sdf.format(t1);
                    int repeat = d.getDose_r();

                        int f = repeat;
                        while (f <= 24){

                            cal.add(Calendar.MINUTE, 0);
                            cal.add(Calendar.SECOND, 0);

                                cal.getTime(); // returns new date object, one hour in the future
                                Date repDose1 = cal.getTime();
                                String repDose = sdf.format(repDose1);
