使用"Intent.putExtra()"方式将带有提醒的事件添加到日历中

Question

我正在尝试使用以下代码将事件添加到日历:

public Intent calPopulation()
{
        Intent calIntent = new Intent(Intent.ACTION_INSERT);
        calIntent.setType("vnd.android.cursor.item/event");
        calIntent.putExtra(CalendarContract.Events.TITLE, this._title);

        GregorianCalendar calDate = new GregorianCalendar(this._year,this._month, this._day, this._hour, this._minute);
        calIntent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, calDate.getTimeInMillis());
        calIntent.putExtra(CalendarContract.EXTRA_EVENT_END_TIME, calDate.getTimeInMillis()+60*60*1000);
        calIntent.putExtra(CalendarContract.Events.HAS_ALARM, true);
        calIntent.putExtra(CalendarContract.Reminders.EVENT_ID, CalendarContract.Events._ID);
        calIntent.putExtra(CalendarContract.Events.ALLOWED_REMINDERS, "METHOD_DEFAULT");
        calIntent.putExtra(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);

        calIntent.putExtra(CalendarContract.Reminders.MINUTES,5);
        return calIntent;
}

然后使用以下命令启动操作: startActivity(mTask.calPopulation());

我没有任何问题,日历应用程序事件使用我输入到我的应用程序中的正确信息启动,除了它没有填写我想要添加的提醒的事件.

你有线索吗？我尝试使用这种方法在很多线程中搜索(我的意思是intent.putExtra),但从未发现任何有趣的东西.

还有一点,有没有办法直接将事件+提醒保存到日历中而无需打开日历应用程序并请求用户操作？

提前致谢.亚历克斯.

根据我指出的方法没有答案,但我发现另一种方法是在日历中添加带提醒的事件.

以下方法对我来说很好:

// Add an event to the calendar of the user.
    public void addEvent(Context context) {
        GregorianCalendar calDate = new GregorianCalendar(this._year, this._month, this._day, this._hour, this._minute);

        try {
            ContentResolver cr = context.getContentResolver();
            ContentValues values = new ContentValues();
            values.put(CalendarContract.Events.DTSTART, calDate.getTimeInMillis());
            values.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis()+60*60*1000);
            values.put(CalendarContract.Events.TITLE, this._title);
            values.put(CalendarContract.Events.CALENDAR_ID, 1);
            values.put(CalendarContract.Events.EVENT_TIMEZONE, Calendar.getInstance()
                    .getTimeZone().getID());
            System.out.println(Calendar.getInstance().getTimeZone().getID());
            Uri uri = cr.insert(CalendarContract.Events.CONTENT_URI, values);

            // Save the eventId into the Task object for possible future delete.
            this._eventId = Long.parseLong(uri.getLastPathSegment());
            // Add a 5 minute, 1 hour and 1 day reminders (3 reminders)
            setReminder(cr, this._eventId, 5);
            setReminder(cr, this._eventId, 60);
            setReminder(cr, this._eventId, 1440);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // routine to add reminders with the event
    public void setReminder(ContentResolver cr, long eventID, int timeBefore) {
        try {
            ContentValues values = new ContentValues();
            values.put(CalendarContract.Reminders.MINUTES, timeBefore);
            values.put(CalendarContract.Reminders.EVENT_ID, eventID);
            values.put(CalendarContract.Reminders.METHOD, CalendarContract.Reminders.METHOD_ALERT);
            Uri uri = cr.insert(CalendarContract.Reminders.CONTENT_URI, values);
            Cursor c = CalendarContract.Reminders.query(cr, eventID,
                    new String[]{CalendarContract.Reminders.MINUTES});
            if (c.moveToFirst()) {
                System.out.println("calendar"
                        + c.getInt(c.getColumnIndex(CalendarContract.Reminders.MINUTES)));
            }
            c.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    // function to remove an event from the calendar using the eventId stored within the Task object.
    public void removeEvent(Context context) {
        ContentResolver cr = context.getContentResolver();

        int iNumRowsDeleted = 0;

        Uri eventsUri = Uri.parse(CALENDAR_URI_BASE+"events");
        Uri eventUri = ContentUris.withAppendedId(eventsUri, this._eventId);
        iNumRowsDeleted = cr.delete(eventUri, null, null);

        Log.i(DEBUG_TAG, "Deleted " + iNumRowsDeleted + " calendar entry.");
    }


    public int updateEvent(Context context) {
        int iNumRowsUpdated = 0;
        GregorianCalendar calDate = new GregorianCalendar(this._year, this._month, this._day, this._hour, this._minute);

        ContentValues event = new ContentValues();

        event.put(CalendarContract.Events.TITLE, this._title);
        event.put("hasAlarm", 1); // 0 for false, 1 for true
        event.put(CalendarContract.Events.DTSTART, calDate.getTimeInMillis());
        event.put(CalendarContract.Events.DTEND, calDate.getTimeInMillis()+60*60*1000);

        Uri eventsUri = Uri.parse(CALENDAR_URI_BASE+"events");
        Uri eventUri = ContentUris.withAppendedId(eventsUri, this._eventId);

        iNumRowsUpdated = context.getContentResolver().update(eventUri, event, null,
                null);

        // TODO put text into strings.xml
        Log.i(DEBUG_TAG, "Updated " + iNumRowsUpdated + " calendar entry.");

        return iNumRowsUpdated;
    }

希望这可以帮助其他遇到同样问题的人:).
