Фрагмент лезет на другой фрагмент во время навигации

/ 19 сентября 2019

У меня есть некоторые проблемы с анимацией, я думаю, дело в том, что, когда я перемещаюсь от одного фрагмента к другому (от DayFragment до LessonFragment), анимация работает неправильно, и у меня есть 2 секунды этого просмотра (один фрагмент взбирается на другой):

У меня недостаточно репутации для публикации изображений, извините за это. Ссылки для просмотра проблемы с анимацией: https://i.imgur.com/XYZi9cR.png, https://i.imgur.com/ArXtDBg.png

Я читал раньше, и кто-то сказал, что проблема с анимацией может быть вызвана наблюдателями во Fragment (потому что обновление от viewmodel приходит каждую секунду (у меня таймер в viewModel)), но я отменил регистрацию от наблюдателей в onPause, так что решение не работает для меня, или я сделал что-то не так.

Итак, цель исправить анимацию

Спасибо за помощь, я пытаюсь исправитьего проблемы за неделю.
