我正在开发具有提醒功能的应用程序。我使用的代码如下来设置提醒和事件:

private void addReminder(int statrYear, int startMonth, int startDay, int startHour, int startMinut, String title){
    // Convert start of begin time of reminder in milliseconds.
    Calendar beginTime = Calendar.getInstance();
    beginTime.set(statrYear, startMonth, startDay, startHour, startMinut);
    long startMillis = beginTime.getTimeInMillis();

    // String to access default google calendar of device for Event setting.
    String eventUriString = "content://com.android.calendar/events";

    // Creation of Event.
    ContentValues eventValues = new ContentValues();
    // Set calendar as 1 for default calendar.
    eventValues.put(Events.CALENDAR_ID, 1);
    // Set title as user define.
    eventValues.put(Events.TITLE, title);
    // Set description as user define.
    eventValues.put(Events.DESCRIPTION, "MYApp");
    // Set location as user define.
    eventValues.put(Events.EVENT_TIMEZONE, "India");
    // Set start time as system time or time converted in milliseconds.
    eventValues.put(Events.DTSTART, startMillis);
    // Set status of event as 1.
    eventValues.put("eventStatus", 1);
    // Set visibility of event as 3 (public).
    eventValues.put("visibility", 3);
    // Set transparency as 0. No other app seen through reminder.
    eventValues.put("transparency", 0);
    // Set alarm as 1. Ringing.
    eventValues.put(Events.HAS_ALARM, 1);

    // Set Event in calendar.
    Uri eventUri = getContentResolver().insert(Uri.parse(eventUriString), eventValues);
    // Getting ID of event in Long.
    long eventID = Long.parseLong(eventUri.getLastPathSegment());

    /***************** Event: Reminder(with alert) Adding reminder to event *******************/
    // String to access default google calendar of device for reminder setting.
    String reminderUriString = "content://com.android.calendar/reminders";
    ContentValues reminderValues = new ContentValues();

    // Set reminder on Event ID.
    reminderValues.put("event_id", eventID);
    // Set reminder minute before.
    reminderValues.put("minutes", 1);
    // Set method of reminder
    reminderValues.put("method", 1);

    @SuppressWarnings("unused")
    //Setting reminder in calendar on Event.
    Uri reminderUri = getContentResolver().insert(Uri.parse(reminderUriString), reminderValues);
}


上面的代码运行正常。
现在需要的应用程序是:


如何获取提醒ID。
如何从上面的代码以编程方式设置的日历中删除提醒。
如何以编程方式编辑现有提醒。
如何进行提醒,隐藏在日历中,仅在警报时间可见。


请指导我的建议。

最佳答案

A.如何获取提醒ID。

您可以通过以下方式获取提醒ID:

Long reminderID = Long.parseLong(reminderUri.getLastPathSegment());


B.如何从以上代码以编程方式设置的日历中删除提醒。

您可以通过调用以下代码从日历中删除提醒:

Uri reminderUri = Uri.parse("content://com.android.calendar/reminders");
reminderUri = Uri.withAppendedPath(reminderUri, String.valueOf(reminderID));
context.getContentResolver().delete(reminderUri, null, null);


C.如何以编程方式编辑现有提醒。

您可以通过在同一事件ID上设置新的更新字段来更新提醒,并通过以下代码添加提醒:

更新事件

Uri updateEventUri = Uri.withAppendedPath(Uri.parse("content://com.android.calendar/events"), String.valueOf(eventID));
context.getContentResolver().update(updateEventUri, eventValues, null, null);


更新提醒

Uri updateReminderUri = Uri.withAppendedPath(Uri.parse("content://com.android.calendar/reminders"), String.valueOf(Utility.eventID));
context.getContentResolver().update(updateReminderUri, reminderValues, null, null);
