android.content.res.Resources $ NotFoundException : 문자열 리소스 ID # 0x42

Question

나는 listview가 있습니다. 각 항목을 클릭하면 편집 텍스트로 경고 대화 상자를 표시하고 입력 값을 정수 변수에 저장합니다. 그러나 오류가 표시됩니다. 입력 텍스트를 변환하지 않으면 잘 작동하지만 Integer.parseInt()를 사용하면 응용 프로그램이 충돌합니다. 여기에 내 코드와 logcat이야.

이 시도 :)

builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { 
       @Override 
       public void onClick(DialogInterface dialog, int which) { 


        strQuantity = quantityInput.getText().toString(); 

        quantity= Integer.parseInt(strQuantity); //int 

        Toast.makeText(getActivity(),String.valueOf(quantity),Toast.LENGTH_LONG).show(); //error here 

        Toast.makeText(getActivity(),"Enter the correct quantity",Toast.LENGTH_LONG).show(); 

       } 
      });
