Вот исправление для вас.Вы должны динамически обновлять поле управления с помощью кода.Идея состоит в том, чтобы добавить один оверлей с элементами управления в файл макета.и когда будет видна панель навигации, обновите нижнее поле элементов управления, чтобы увеличить их на экране.Код отдыха объясняет, что это сработало для меня.
Файл макета: video_player_activity.xml
<?xml version="1.0" encoding="utf-8"?>
