Я создаю приложение. В моем приложении я получаю ответ и отображаю его в настраиваемом диалоговом окне оповещения. Пока все работает нормально, теперь я пытаюсь сделать следующее: если пользователь один раз выбирает элемент в диалоговом окне оповещения, он должен сохранить его в предпочтение так, что нет необходимости получать данные каждый раз.

Ниже приведен мой фрагмент кода.

Следующий ответ, который я получаю:
