Нет данных из API в представлении переработчика с модификацией и привязкой данных
Я пытаюсь получить данные о погоде из Интернета с помощью Retrofit, и у меня есть проблема с отображением данных в программе повторного просмотра. В logcat есть все данные, поэтому API и загрузка данных работают, но утилита просмотра еще пуста.
РЕДАКТИРОВАТЬ: проблема в хранилище, где в моем хранилище, где я хочу получить данные. В logcat что-то вроде этого: ожидаемый BEGIN_ARRAY, но был BEGIN_OBJECT в строке 1, столбец 2, путь $ Это, вероятно, некоторая проблема с преобразованием JSON, но как решить эту проблему в моем случае?

Вы должны установить свой адаптер, после ответа от службы.
@Override
public void onResponse(Call<List<Weather>> call, Response<List<Weather>> response) {
List<Weather> weathers = response.body();//
YourAdapter adapter = new YourAdapter(weathers);
recyclerView.setAdapter(adapter);
}
