Приложение падает при поиске текста в ListView, реализованном в Fragment.Я сделал fragment Адаптер и doSearch();метод который на fragment.В doSearch() метод описывает beforeTextChanged, onTextChanged, afterTextChanged.имена ArrayList, которые поступают из API в формате JSON.Хотите искать имена, но приложение аварийно завершает работу и получает сообщение об ошибке. В Adapter расширено на BaseAdapter.Как я могу решить эту ошибку и найти определенный текст в виде списка.
Может быть что-то не так в методе filter ().Невозможно распознать проблему.
Сейчас в нижней строке адаптера отображается ошибка:
textView.setText(names.get(position));
Ошибка:
java.lang.IndexOutOfBoundsException: Index: 0, Size: 0
