使用'Intent.putExtra（）'的方法添加提醒日历的事件 [英] Adding event with reminders to calendar with 'Intent.putExtra()' way of doing

问题描述

我正在尝试使用以下代码向日历添加事件：

  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; 
} 
  

然后启动该操作： startActivity（mTask我没有任何问题，日历应用程序事件的启动与正确的信息我输入到我的应用程序，除了它不填写我想添加的提醒的事件。

你有什么线索吗？我试图在许多线程中使用这种方法搜索（我的意思是intent.putExtra），但从来没有发现任何有趣的东西。

其他的一点是，有没有办法直接保存事件+提醒进入日历而不打开日历应用程序并请求用户操作？

提前感谢。
Alex。

解决方案

根据我指出的方法没有回答，但我发现添加事件的另一种方式提醒日历。

以下方法对我有用：

  //将事件添加到用户的日历。 
 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）; 
 
 //将eventId保存到Task对象中，以备将来删除。 
 this._eventId = Long.parseLong（uri.getLastPathSegment（））; 
 //添加5分钟，1小时和1天提醒（3个提醒）
 setReminder（cr，this._eventId，5）; 
 setReminder（cr，this._eventId，60）; 
 setReminder（cr，this._eventId，1440）; 
 
} catch（Exception e）{
 e.printStackTrace（）; 
} 
} 
 
 //添加事件事件的例程
 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（）; 
} 
} 
 
 //使用存储在Task对象中的eventId从日历中删除事件的功能。 
 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，已删除+ iNumRowsDeleted +日历条目）; 
} 
 
 
 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为false，1为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将文本放入strings.xml 
 Log.i（DEBUG_TAG，已更新+ iNumRowsUpdated +日历条目）; 
 
 return iNumRowsUpdated; 
} 
  

希望这可以帮助遇到同样问题的其他人：） / p>

I'm trying to add events to calendar with the following code :

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;
}

And then launch the action with : startActivity(mTask.calPopulation());

I don't have any issue, the calendar app event launched with the correct information I entered into my app, except that it does not fill in the event the reminder I would like to add.

Do you have any clues? I tried to search within many threads using this method (I mean the intent.putExtra) but never find anything interesting.

Other point, is there a way to directly save the event + reminder into the calendar without opening calendar App and requesting for user action?

Thanks in advance. Alex.

解决方案

No answer according to the method I pointed out, but another way I found to add event with reminders to the calendar.

Hereunder methods are working fine for me :

// 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;
    }

Hope this could help others that encountered the same problem I had :).
