添加多个提醒会导致它们同时触发

我在这里包含完整的问题描述,因为我不确定解决方案背后的逻辑是否正确,但我很确定它与我设置警报本身的方式有关,导致这种不准确,或者有时只是纯粹的故障(警报根本不会触发).

用户可以从药物列表中添加新药物.

屏幕1

找到某种药物后,点击它会显示此屏幕http://imgur.com/nLC9gTG

该屏幕包含Medication的名称,在"Posology"标题下(绿色栏)是可以添加该Medication的提醒的地方.

忘记"单位"字段.

"频率"字段接受一个数字,"频率"字段右侧的标签是可点击的,它会显示一个下拉菜单,用户可以从中选择"每日时间"或"每周时间".

"星期几"标签(屏幕截图中的标签为空)也是可点击的,它向用户显示一个下拉菜单,用户可以从一周中选择多天.

"治疗持续时间"字段接受一个数字,"治疗持续时间"字段右侧的标签将反映用户选择的"频率"(如果是"每周一次",那么该标签将说"周",如果是"每月一次"然后该标签将说"几个月").

屏幕2

在第二个屏幕截图中http://imgur.com/AcUmlHH - 有一个开关允许用户启用他试图添加的此药物(项目,实例等)的提醒.

如果上面的"频率"字段的数字大于0(例如2),则提醒开关将创建一个提醒字段列表,它将显示在"获取通知"绿色栏的下方.

当用户最终按下"添加药物"时,将在数据库中创建新的药物对象,以及用户为此药物对象选择添加的"频率"(提醒的数量).

创建一个Medication表:

id
name
description
dosage
frequency
frequencyType
treatmentDuration
ForeignCollection
ArrayList (DayChoice is a class with "Day Name" and "Selected")
when
whenString
units
unitForm
remarks
remindersEnabled

创建MedicationReminder表:

Medication (foreign key for the Medication table)
Calendar
int[] days_of_week
totalTimesToTrigger

在创建此新的Medication对象时:

Medication medication = new Medication();
medication.setFrequency()
medication.setName().setDosage().setRemindersEnabled()....

assignForeignCollectionToParentObject(medication);

assignForeignCollectionToParentObject(药物)

private void assignForeignCollectionToParentObject(Medication medicationObject) {
    medicationDAO.assignEmptyForeignCollection(medicationObject, "medicationReminders");

    MedicationRemindersRecyclerAdapter adapter =
        (MedicationRemindersRecyclerAdapter) remindersRecyclerView.getAdapter();

    //Clear previous reminders
    medicationObject.getMedicationReminders().clear();

    for (int i = 0; i < adapter.getItemCount(); i++) {
      int realDaysSelected = 0;

      MedicationReminder medReminder = adapter.getItem(i);
      medReminder.setMedication(medicationObject);
      medReminder.setDays_of_week(daysOfWeekArray);

      //These days are populated when the user selected them from the "Days of Week" clickable label
      for (int aDaysOfWeekArray : daysOfWeekArray) {
        if (aDaysOfWeekArray != 0) realDaysSelected++;
      }

      medReminder.setTotalTimesToTrigger(
          Integer.parseInt(treatmentDurationET.getText().toString()) * realDaysSelected);
      medicationObject.getMedicationReminders().add(medReminder);
    }

    setupMedicationReminders(medicationObject.getMedicationReminders().iterator());
}

setupMedicationReminders()

public void setupMedicationReminders(Iterator medicationRemindersIterator) {
    PendingIntent pendingIntent;
    AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

    while (medicationRemindersIterator.hasNext()) {
      MedicationReminder medReminder = medicationRemindersIterator.next();

      for (int i = 0; i < medReminder.getDays_of_week().length; i++) {

        int dayChosen = medReminder.getDays_of_week()[i];

        if (dayChosen != 0) {
          medReminder.getAlarmTime().setTimeInMillis(System.currentTimeMillis());
          medReminder.getAlarmTime().set(Calendar.DAY_OF_WEEK, dayChosen);

          Intent intent = new Intent(AddExistingMedicationActivity.this, AlarmReceiver.class);
          intent.putExtra(Constants.EXTRAS_ALARM_TYPE, "medications");
          intent.putExtra(Constants.EXTRAS_MEDICATION_REMINDER_ITEM, (Parcelable) medReminder);

          pendingIntent = PendingIntent.getBroadcast(this, medReminder.getId(), intent,
              PendingIntent.FLAG_UPDATE_CURRENT);

          int ALARM_TYPE = AlarmManager.ELAPSED_REALTIME_WAKEUP;

          if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            am.setExactAndAllowWhileIdle(ALARM_TYPE, medReminder.getAlarmTime().getTimeInMillis(),
                pendingIntent);
          } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            am.setExact(ALARM_TYPE, medReminder.getAlarmTime().getTimeInMillis(), pendingIntent);
          } else {
            am.set(ALARM_TYPE, medReminder.getAlarmTime().getTimeInMillis(), pendingIntent);
          }
        }
      }
    }
}

问题是当添加药物提醒时,它们总是在被添加后不久被触发,并且全部同时被触发.

假设我选择周六和周五的频率2,治疗持续时间为1周.这意味着将添加总共4个提醒,周五为2,周六为2.

当我这样做,它恰好是一个星期六,警报同时在星期六同时触发.

怎么了？
