Ресурсы не найдены Исключение из использования setText

Question

Я впервые встретил эту ошибку, поэтому я действительно не знаю, как ее исправить. Я думаю, что моя проблема заключалась в использовании метода setText. Я не знаю почему. Мой код отлично работает, прежде чем я модифицировал некоторые из моих кодов. И теперь я получаю эту ошибку. Ниже мой код,

Answer 1

Вашей ошибка, вероятно, следует в этой строке:

if(data==null) 
    { 
     // viewHolder.quantity.setText(list.get(position).quantity); <---ERROR HERE 
     // Probably quantity is not a string, so use String.valueOf Function here 
      viewHolder.quantity.setText(String.valueOf(list.get(position).quantity)); 

    } 
    else{ 
     // data is already declared a string. So, String.valueOf is not required. 
     viewHolder.quantity.setText(data); 
    } 

В соответствии с ответом here SetText с струнными отображают значения, как, например, в то время как, SetText с междунаром пытается найти ресурс, соответствующее значение INT.
