Как исправить проблему «ArrayIndexOutOfBoundsException»?

Question

Произошла ошибка в logcat, может ли кто-нибудь сказать, что значит?

private int getDayIdxInTrip(int position) { 
DayTagItem item = null; 
    Integer dayIdx = -1; 
    try { 
     if (mTripItems.get(position).mViewType == TripDetailAdapter.DAYTAG_TYPE) { 
      item = (DayTagItem) mTripItems.get(position); 
     } else { 
      Logger.e(TAG, "Wrong view type found on position == " 
        + position); 
      position--; 
      return getDayIdxInTrip(position); 
     } 
     dayIdx = Integer 
       .parseInt(item.mDayIdx != null 
         && !item.mDayIdx.trim().equals("") 
         && !item.mDayIdx.trim().equalsIgnoreCase("null") ? item.mDayIdx 
         : "0"); 
    } catch (Exception e) { 
     Logger.e(TAG, "getDayIdxInTrip() error!"+e.getMessage()); 
    } 
    Logger.i(TAG,"returned"+dayIdx); 
    return dayIdx; 
}

Answer 1

Из документации:

Брошенный, чтобы указать, что массив был доступен с незаконным . Индекс является либо отрицательным, либо большим или равным размеру .

Пример:

int myArray = new int[10]; 
myArray[11] = 123; 

Без кода мы не можем помочь много.
