Reminder/Events 未收到通知

Question

我想通过使用下面的代码在 android Calender 中设置提醒和事件我能够在 android 日历中看到事件，但该事件没有被通知或正在警报或 anything.I 正在使用 timpicker 用于特定 time.My 问题是提醒，事件未通知或警报。代码或其他方面是否有问题？

   btnSetAlarm.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    TimePickerDialog timePickerDialog = new TimePickerDialog(getActivity(), new TimePickerDialog.OnTimeSetListener() {
                        @Override
                        public void onTimeSet(TimePicker timePicker, int hours, int minutes) {

                            setEvents(hours,minutes);

                        }
                    }, hour, minute, false);
                    timePickerDialog.show();
                }
            });

 private void setReminders(Long eventID) {

        Calendar calendar=Calendar.getInstance();
        ContentResolver cr = getActivity().getContentResolver();
        ContentValues reminders = new ContentValues();
        reminders.put(CalendarContract.Reminders.EVENT_ID, eventID);
        reminders.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALARM);
        reminders.put(CalendarContract.Reminders.MINUTES,5);
        Uri eventsUri = Uri.parse("content://com.android.calendar/reminders");
        // event is added
        cr.insert(eventsUri, reminders);
    }

    private void setEvents(int hours, int minutes) {

        Calendar calNow = Calendar.getInstance();
        Calendar calSet = (Calendar) calNow.clone();

        calSet.set(Calendar.HOUR_OF_DAY, hours);
        calSet.set(Calendar.MINUTE, minutes);
        calSet.set(Calendar.SECOND, 0);
        calSet.set(Calendar.MILLISECOND, 0);

        ContentResolver cr = getActivity().getContentResolver();
        ContentValues values = new ContentValues();
        values.put(CalendarContract.Events.DTSTART, calSet.getTimeInMillis());
        values.put(CalendarContract.Events.DTEND, calSet.getTimeInMillis() + 10000 );
        values.put(CalendarContract.Events.HAS_ALARM,1);
        values.put(CalendarContract.Events.TITLE, "My Title");
        values.put(CalendarContract.Events.DESCRIPTION, "Android Development");
        values.put(CalendarContract.Events.CALENDAR_ID, 1);
        values.put(CalendarContract.Events.EVENT_TIMEZONE, Calendar.getInstance().getTimeZone().getID());

        Uri eventsUri = Uri.parse("content://com.android.calendar/events");
        // event is added
        Uri uri=cr.insert(eventsUri, values);


        // get the Event ID That is the Last element in the Uri
        Long eventID = Long.parseLong(uri.getLastPathSegment());
        Log.e(TAG, "" + eventID);
        setReminders(eventID);

    }

真正的问题出在设备 Redmi Note 2 上，它没有为 Calender 事件提供适当的 BroadcastListner，需要从设置证券中手动启用权限，并且需要在 [=12] 中设置我们的应用程序=] 模式以便收听广播因此简而言之这是与设备相关的问题我已经在其他设备上验证了这个代码，它工作正常

Answer 2

来自文档：

The alarm method, as set on the server. METHOD_DEFAULT, METHOD_ALERT, METHOD_EMAIL, METHOD_SMS and METHOD_ALARM are possible values; the device will only process METHOD_DEFAULT and METHOD_ALERT reminders (the other types are simply stored so we can send the same reminder info back to the server when we make changes).

RemindersColumns#METHOD

尝试将 CalendarContract.Reminders.METHOD_ALARM 更改为 CalendarContract.Reminders.METHOD_ALERT
