Android日曆。

Question

我有一個向Calendar.I添加條目的問題，我嘗試了很多測試但沒有成功。

的源代碼：

String calName; 
     String calId = null; 
     String[] projection = new String[] { "_id", "name" }; 

     Uri calendars = Uri.parse("content://com.android.calendar/calendars"); 
     Cursor managedCursor = managedQuery(calendars, projection, "selected=1", null, null); 
     ContentValues event = new ContentValues(); 

     DateFormat date = new SimpleDateFormat("dd/MM/yyyy hh:mm"); 
     long time = System.currentTimeMillis(); 
     String StartTime = date.format(time); 
     String EndTime = "13/4/2011 15:30"; 

     Log.d(TAG, "Value of timeStr: " + StartTime); 



     if (managedCursor.moveToFirst()) { 

      int nameColumn = managedCursor.getColumnIndex("name"); 
      int idColumn = managedCursor.getColumnIndex("_id"); 

      do{ 
       calName = managedCursor.getString(nameColumn); 
       calId = managedCursor.getString(idColumn); 

       event.put("calendar_id", calId); 
       event.put("title", "Event Title"); 
       event.put("description", "Description"); 
       event.put("eventLocation", "New York"); 
       event.put("dtstart", StartTime); 
       event.put("dtend", EndTime); 

       Uri eventsUri = Uri.parse("content://com.android.calendar/events"); 
       Uri calUri = getContentResolver().insert(eventsUri, event); 
      } 
      while (managedCursor.moveToNext()); 
      } 
       } 
} 

錯誤：

Answer 1

開始和結束時間必須是多頭，而不是字符串：

event.put("dtstart", StartTime); 
event.put("dtend", EndTime); 

當你試圖把在「11/04/2011「，解析這個很長時間失敗，你會得到異常。

嘗試通過在多頭：

long now = System.currentTimeMillis(); 
event.put("dtend",now);
