У меня проблема в constraintLayout. Я ограничил кнопку в нижней части родительского элемента в макете фрагмента A. Теперь моя кнопка не видна, пока я не нажму в любом месте моего макета. На самом деле кажется, что кнопка прыгает Наверное, возможно, проблема в coordinateLayout. Я никогда не устанавливал видимость этой кнопки в своем фрагменте. Это мой макет xml.
