Я показал тост, чтобы проверить, работает ли фрагмент, и работает отлично. Toast отображает «done» и количество выбранных списков. , но все же фрагмент отображается пустым, кажется, что адаптер или просмотр ресайклера не работают. Пожалуйста, помогите, спасибо.
нет он не работает она имеет тот же результат. –
