事件添加Android設備日曆應用4.0

Question

我想在Android設備日曆App 4.0中添加事件。如果我在日曆API中使用ID = 1，則事件成功添加，但如果我使用不同的ID，則事件不會添加到日曆應用中。任何暗示都會很有價值。在此先感謝我使用以下代碼

long ids = -1; 
long startMillis = 0; 
long endMillis = 0; 
Calendar beginTime = Calendar.getInstance(); 
//beginTime.set(2013, 10, 29, 5,40); 
startMillis = beginTime.getTimeInMillis(); 
Calendar endTime = Calendar.getInstance(); 
// endTime.set(2013, 10, 30, 4, 20); 
endMillis= endTime.getTimeInMillis(); 
Calendar cal = Calendar.getInstance(); 
// Insert Event 
cr=getContentResolver(); 
ContentValues values = new ContentValues(); 
values.put(CalendarContract.Events.CALENDAR_ID, eventId); 
values.put(CalendarContract.Events.TITLE, title); 
values.put(CalendarContract.Events.DTSTART, startMillis); 
values.put(CalendarContract.Events.DTEND, endMillis+60*60*1000); 
//values.put(CalendarContract.Events.STATUS, "null"); 
TimeZone tz = TimeZone.getDefault(); 
values.put(CalendarContract.Events.EVENT_TIMEZONE, tz.getID()); 

Uri uri = cr.insert(
     CalendarContract.Events.CONTENT_URI, values);

確保其中插入數據的日曆ID存在：

檢查一次：

public void getCalendarsList() { 
    String[] projection = new String[]{"_id"}; 
    Uri calendars; 
    if (Build.VERSION.SDK_INT >= 8) { 
     calendars = Uri.parse("content://com.android.calendar/calendars"); 
    } else { 
     calendars = Uri.parse("content://calendar/calendars"); 
    } 
    Cursor cursor = this.managedQuery(calendars, projection, null, null, null); //get all calendars 
    if (cursor.moveToFirst()) { 
     String calId; 
     int l_idCol = cursor.getColumnIndex(projection[0]); 
     do { 
      calId = cursor.getString(l_idCol); 

     } while (cursor.moveToNext()); 
    } 
    }
