Я работаю над приложением nearyPlaces, которое помогает пользователям находить близлежащие места вокруг них. Я использовал библиотеку retrofit для получения ответа от Google API. Все работает отлично, как вы можете видеть здесь . Так. Я хочу проанализировать эти результаты внутри recyclerView, как карты Google. Проблема в том, что после consuming API, он отображается как object вместо arrayList.
Мне действительно нужны указания по этому вопросу, так как это дало мне головную боль на несколько недель.

} Как видите, я уже получаю данные внутри NearbyPlaces Класс, который содержит класс AsyncTask. Поэтому я думаю, что мне нужно сделать, это выяснить, как перенести данные из моей асиновой задачи c в мою adapter, чтобы я мог показать с помощью recyclerView.
