无法在Google日历中插入多个事件

Question

在我的应用程序中，我使用CalendarContract API来管理Google日历上的日历和事件。将多个活动添加到单个日历时遇到一些问题。一般来说，这种方法的问题是，每当我向Google日历添加新事件时，旧事件将被新事件所替代。这里是我的方法的代码：

public int addEvent(Context context, String color, int calendarId, String name, String location, String description, Date dateBegin, Date dateEnd) { 
      long startMillisEpoch; 
      long endMillisEpoch; 

      Calendar beginTime = Calendar.getInstance(); 
      beginTime.setTime(dateBegin); 
      startMillisEpoch = beginTime.getTimeInMillis(); 

      Calendar endTime = Calendar.getInstance(); 
      endTime.setTime(dateEnd); 
      endMillisEpoch = endTime.getTimeInMillis(); 

      int eventColor; 
      try { 
       eventColor = Color.parseColor(color); 
      } catch (Exception e) { 
       // Get a random color 
       Random random = new Random(); 
       eventColor = MyApp.RANDOM_COLORS[random.nextInt(MyApp.RANDOM_COLORS.length)]; 
      } 
      ContentValues values = new ContentValues(); 
      values.put(CalendarContract.Events.CALENDAR_ID, calendarId); 
      values.put(CalendarContract.Events.DTSTART, startMillisEpoch); 
      values.put(CalendarContract.Events.DTEND, endMillisEpoch); 
      values.put(CalendarContract.Events.TITLE, name); 
      values.put(CalendarContract.Events.EVENT_LOCATION, location); 
      values.put(CalendarContract.Events.DESCRIPTION, description); 
      values.put(CalendarContract.Events.EVENT_COLOR, eventColor); 
      // NOTE: Every event MUST have a timezone. Otherwise, 
      // the application will throw an IllegalArgumentException 
      values.put(CalendarContract.Events.EVENT_TIMEZONE, TimeZone.getDefault().getDisplayName()); 
      // Put default values 
      values.put(CalendarContract.Events.ALL_DAY, NON_ALL_DAY); 
      values.put(CalendarContract.Events.GUESTS_CAN_INVITE_OTHERS, 1); 
      Uri calUri = context.getContentResolver().insert(CalendarContract.Events.CONTENT_URI, values); 
      if (calUri != null) { 
       try { 
        return Integer.parseInt(calUri.getLastPathSegment()); 
       } catch (Exception e) { 
        return -1; 
       } 
      } 
      return -1; 
     } 

解决这类问题的任何想法？亲切的问候。

根据API我猜你错过.execute()

Uri calUri = context.getContentResolver() 
        .insert(CalendarContract.Events.CONTENT_URI, values) 
        .execute();
