使用重複規則無法讀取日曆事件

Question

我使用重複規則「FREQ = MONTHLY; BYMONTHDAY = 16; COUNT = 10」創建了一個事件。我在我的兩個Android日曆應用中以及Google日曆網站上看到了該事件。我可以從我的應用程序中讀取所有其他事件，但我沒有看到此事件。唯一的區別是這個事件有重複規則。這是我的閱讀代碼。

public static MyEvents readCalendarMyEvent(Context context,Date date1, Date date2, int calendarID) 
{ 
    try 
    { 
      Calendar calendar1 = Calendar.getInstance(); 
      calendar1.setTime(date1); 
      Calendar calendar2 = Calendar.getInstance(); 
      calendar2.setTime(date2); 
      Uri l_eventUri; 

      if (Build.VERSION.SDK_INT >= 8) { 
       l_eventUri = Uri.parse("content://com.android.calendar/events"); 
      } else { 
       l_eventUri = Uri.parse("content://calendar/events"); 
      } 
      ContentResolver contentResolver = context.getContentResolver(); 
      String dtstart = "dtstart"; 
      String dtend = "dtend"; 

      String[] l_projection = new String[] { CalendarContract.Events.CALENDAR_ID, 
        CalendarContract.Events.TITLE, //1 
        CalendarContract.Events.DESCRIPTION, 
        CalendarContract.Events.DTSTART, 
        CalendarContract.Events.DTEND, 
        CalendarContract.Events.EVENT_LOCATION, 
        CalendarContract.Events.EVENT_TIMEZONE,//6 
        CalendarContract.Events.HAS_ALARM, 
        CalendarContract.Events.RRULE, 
        CalendarContract.Events.RDATE, 
        CalendarContract.Events.ORGANIZER, 
        CalendarContract.Events.SELF_ATTENDEE_STATUS,//11 
        CalendarContract.Events.GUESTS_CAN_MODIFY, 
        CalendarContract.Events._ID,     
        CalendarContract.Events.ALL_DAY, 
        CalendarContract.Events.DELETED, 
        CalendarContract.Events.GUESTS_CAN_INVITE_OTHERS,//16

        CalendarContract.Events.EXDATE 
        }; 
      String where = "(" + dtstart + ">" 
        + calendar1.getTimeInMillis() + " and " 
        + dtend + "<" + calendar2.getTimeInMillis() + " and "+ 
        CalendarContract.Events.CALENDAR_ID + " = '" + String.valueOf(calendarID) +"')"; 
      Cursor cursor= contentResolver.query(l_eventUri, l_projection, where, null, 
        "dtstart ASC"); 
      cursor.moveToFirst(); 
      // fetching calendars id 
      String str=""; 
      MyEvents myEvents = new MyEvents(); 
      for (int i = 0; i < cursor.getCount(); i++) { 
       int delete = cursor.getInt(15); 
       if(delete == 1) 
       { 
        cursor.moveToNext(); 
        continue; 
       } 
       MyEvent myEvent = new MyEvent(); 
       myEvent.ID = cursor.getInt(0); 
       myEvent.TITLE = cursor.getString(1);    
       myEvent.Note = cursor.getString(2); 
       str = cursor.getString(3); 
       if(str != null || str.length() <1) 
       { 
        myEvent.START_DATE = MillisecondsToDateTime(Long.parseLong(str)); 
        myEvent.StartDate = getDate(Long.parseLong(str)); 
       } 
       else 
       { 
        cursor.moveToNext(); 
        continue;    
       } 
       str = cursor.getString(4); 
       if(str != null || str.length() <1) 
        myEvent.END_DATE = MillisecondsToDateTime(Long.parseLong(str));

       myEvent.EXDATE = cursor.getString(22);   
       myEvents.Add(myEvent); 
       cursor.moveToNext();

    catch(Exception ex) 
    { 
     ex.printStackTrace();

    return new MyEvents(); 
}

問題已解決。我在where子句中犯了一個錯誤。以下內容正確

 String where = "(" + dtstart + ">" 
        + calendar1.getTimeInMillis() + " and " 
        + dtstart + "<" + calendar2.getTimeInMillis() + " and "+ 
        CalendarContract.Events.CALENDAR_ID + " = '" + String.valueOf(calendarID) +"')";
