Данные, запрашиваемые из пожарной базы, не отображаются в обзоре и в сетке.

/ 29 сентября 2019

Я запросил данные из Firebase и добавил их в horizontalscrollmodellist и viewalllist и передал их адаптеру домашней страницы, чтобы отобразить их в макете сетки и горизонтальной прокрутке, чтобы они отлично отображали запрашиваемые данные на домашней странице. но если я передаю тот же список из адаптера, чтобы просмотреть все действия для отображения в представлении переработчика и в представлении сетки, то, кажется, все в порядке и без ошибок, но когда приложение запускает представление, все действия не отображают данные в представлении сетки и представлении переработчика. Я перепробовал все, но проблема сохраняется. Пожалуйста, помогите мне с этим.

Спасибо всем заранее!
