Панель действий / панель инструментов Android исчезает после записи в edittext

Я застрял в этом. У меня есть приложение, в котором у меня есть несколько страниц, сделанных в виде фрагментов. Каждая страница хороша, кроме последней, где, когда я нажимаю на editText, панель действий исчезает, а когда я расфокусирую ее, панель действий больше не отображается.

Я пробовал изменить appTheme на все виды тем, но они ничего не меняли, большинство из них вынуждали приложение вылетать.

Вот мой макет этой страницы
