Я новичок в Android, я пытаюсь создать страницу профиля для тестового приложения.Я хотел бы прокрутить часть сведений о профиле, оставив только представление вкладки при прокрутке.Проблема заключается в том, что textView profile_username и profile_goals не отображают текст, даже если он жестко запрограммирован.Они видны только когда я помещаю profile_details в представление прокрутки.Это как-то связано с поведением collapsibleToolbars?
