安卓：设置提醒功能 [英] Android : Set reminder functionality

问题描述

我发展与提醒功能的应用程序。在code I采用的是如下设置提醒和事件：

I am developing an application with reminder functionality. The code i used is as follows to set the reminder and event:

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);
}

以上code运行正常。
现在在需要应用是：

1. 如何获得提醒标识。


2. 如何从我的日历编程上述code设置删除提醒。


3. 如何以编程方式编辑现有的提醒。


4. 如何做提醒，隐藏在日历和它去仅可见报警的时间。

请指导我用你的建议。

推荐答案

一个。如何获得提醒标识。

A. How to get reminder id.

您可以让您的提醒标识为：

You can get your reminder ID as :

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

乙。如何从我的日历programmetically上述code设置删除提醒。

B. How to delete reminder from my calender programmetically set by the above code.

您可以通过调用以下code从日历中删除提醒：

You can delete reminder from the calender by calling the following code :

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

℃。如何编辑现有提醒programmetically。

C. How to edit existing reminder programmetically.

您可以通过设置在同一事件ID，并提醒新更新的字段按照code更新提醒：

You can update reminder by setting new updated fields on same event id and reminder in by following code :

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);
