} 

, когда я выбираю последний пункт «Петак 4» в блесны и удалить item с кнопкой,

этот код работа если внутри onClick кнопка способ, с корпусом переключателя.

но когда я поставил код внутри onActivityResult, приложение заставит близко

String myData = toList.getSelectedItem().toString(); 
       int position = dataAdapter.getPosition(myData); 


       if(position >= 0){ 
       dataAdapter.remove(myData); 
       dataAdapter.notifyDataSetChanged(); 
       } 
       else { 
       Toast.makeText(getBaseContext(), myData + " not in Spinner", Toast.LENGTH_LONG).show(); 
       } 



      View b = findViewById(R.id.btnPupukQuit); 
      b.setVisibility(View.GONE); 
      onBackPressed(); 
      onAttachedToWindow();

как исправить ошибку indexoutofboundsexception?

его о ArrayList?

Answer 1

Вы звоните dataAdapter.remove() без изменения выбранного индекса в вашем вертушка. Затем в вашей функции SaveData() вызывается spinner1.getSelectedItem(), что приводит к IndexOutOfBoundsException.

Решение? Установите выбранный индекс на то, что все еще существует после удаления элемента из вашего адаптера.

Answer 2

Да, речь идет о ArrayList в вашем коде. В какой-то момент ваш dataAdapter имеет размер 3, и вы пытаетесь получить доступ к элементу по индексу 3, который бросает IndexOutOfBoundsException. Всегда помните, что если размер вашего ArrayList равен x, вы можете получить доступ только до индекса x-1.

Например: Если размер 4, то

list.get(3) - Разрешена

list.get(4) - Не допускается

Answer 3

Если вы хотите получить Spinner позицию выбранного товара, то просто пойти с

spinner.getSelectedItemPosition() which gives integer value.. 

почему использовать

String myData = toList.getSelectedItem().toString(); 
int position = dataAdapter.getPosition(myData); // I think the problem is here 

можно непосредственно инициализировать

int position = toList.getSelectedItemPosition();
