Exoplayer с Recyclerview

Question

У меня есть видео-канал (похожий на TikTok), но когда я провожу пальцем вверх, воспроизводится новое видео, но старое продолжает проигрываться. Мне удалось получить прослушиватель страниц, но я не могу управлять ExoPlayer из «Домашнего фрагмента».

Есть идеи, как вызвать что-то внутри адаптера RecyclerView из домашнего фрагмента?

Если есть лучшее решение для этого, пожалуйста, скажите мне.

Спасибо.

Домашний фрагмент

Вам необходимо обнаружить действия смахивания и отменить видео в предыдущем элементе, прежде чем воспроизводить новое после смахивания. Вы можете проверить здесь , как реализовать слушателя.
