android - 如何使用事件 URI 以编程方式向日历事件添加提醒？

Question

我正在尝试弄清楚如何在我的 Android 应用程序中向日历事件添加提醒。下面用红色圈出的图像是我想以编程方式添加到图像下方的代码中的内容。这就是我遇到的困难。我将不胜感激!

这就是我目前所拥有的...除了我需要帮助的部分外，一切正常。

 public void addEventToCalendar(String EventTitle, String EventDescription, String EventLocation, int EventStartDateYear, int EventStartDateMonth, int EventStartDateDay, int EventEndDateYear, int EventEndDateMonth, int EventEndDateDay, int BeginHour, int BeginMin, int EndHour, int EndMin, Boolean AllDay, String EventFrequency) {
        Toast.makeText(this, "Adding Event To Your Calendar...", Toast.LENGTH_SHORT).show();
        ContentValues event = new ContentValues();
        Calendar startcalendar = Calendar.getInstance();
        Calendar endcalendar = Calendar.getInstance();
        startcalendar.set(EventStartDateYear, EventStartDateMonth, EventStartDateDay, BeginHour, BeginMin);
        endcalendar.set(EventStartDateYear, EventEndDateMonth, EventEndDateDay, EndHour, EndMin);
        event.put(CalendarContract.Events.CALENDAR_ID, 1);
        event.put(CalendarContract.Events.TITLE, EventTitle);
        event.put(CalendarContract.Events.DESCRIPTION, EventDescription);
        event.put(CalendarContract.Events.EVENT_LOCATION, EventLocation);
        event.put(CalendarContract.Events.DTSTART, startcalendar.getTimeInMillis());
        event.put(CalendarContract.Events.DTEND, endcalendar.getTimeInMillis());
        event.put(CalendarContract.Events.ALL_DAY, AllDay);
        event.put(CalendarContract.Reminders.MINUTES, 5); //this here is what I am trying to figure out... 5 minutes before event or 5 hours before event, or 5 days before event, etc.
        event.put(CalendarContract.Events.HAS_ALARM, true);
        event.put(CalendarContract.Events.RRULE, EventFrequency);
        event.put(CalendarContract.Events.EVENT_TIMEZONE, "GMT-05:00");
        if (android.os.Build.VERSION.SDK_INT <= 7) {
        eventsUri = Uri.parse("content://calendar/events");
    } else {
        eventsUri = Uri.parse("content://com.android.calendar/events");
    }
    Uri url = getContentResolver().insert(eventsUri, event);
        Toast.makeText(this, "Event Added To Your Calendar!", Toast.LENGTH_SHORT).show();
}
}

您需要在 CalendarContract.Reminders 中插入一个条目，例如

public void addEventToCalendar(String EventTitle, String EventDescription, String EventLocation, int EventStartDateYear, int EventStartDateMonth, int EventStartDateDay, int EventEndDateYear, int EventEndDateMonth, int EventEndDateDay, int BeginHour, int BeginMin, int EndHour, int EndMin, Boolean AllDay, String EventFrequency) {
    Toast.makeText(this, "Adding Event To Your Calendar...", Toast.LENGTH_SHORT).show();
    ContentValues event = new ContentValues();
    Calendar startcalendar = Calendar.getInstance();
    Calendar endcalendar = Calendar.getInstance();
    startcalendar.set(EventStartDateYear, EventStartDateMonth, EventStartDateDay, BeginHour, BeginMin);
    endcalendar.set(EventStartDateYear, EventEndDateMonth, EventEndDateDay, EndHour, EndMin);
    event.put(CalendarContract.Events.CALENDAR_ID, 1);
    event.put(CalendarContract.Events.TITLE, EventTitle);
    event.put(CalendarContract.Events.DESCRIPTION, EventDescription);
    event.put(CalendarContract.Events.EVENT_LOCATION, EventLocation);
    event.put(CalendarContract.Events.DTSTART, startcalendar.getTimeInMillis());
    event.put(CalendarContract.Events.DTEND, endcalendar.getTimeInMillis());
    event.put(CalendarContract.Events.ALL_DAY, AllDay);
    event.put(CalendarContract.Events.HAS_ALARM, true);
    event.put(CalendarContract.Events.RRULE, EventFrequency);
    event.put(CalendarContract.Events.EVENT_TIMEZONE, "GMT-05:00");

    Uri url = getContentResolver().insert(CalendarContract.Events.CONTENT_URI, event);

    long eventId = Long.parseLong(url.getLastPathSegment());

    ContentValues reminder = new ContentValues();
    reminder.put(CalendarContract.Reminders.EVENT_ID, eventId);
    reminder.put(CalendarContract.Reminders.MINUTES, 10);
    reminder.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
    getContentResolver().insert(CalendarContract.Reminders.CONTENT_URI, reminder);

    Toast.makeText(this, "Event Added To Your Calendar!", Toast.LENGTH_SHORT).show();
}
