У меня есть следующий axml, который включает в себя кнопку с плавающим действием, которую я использую для предоставления инструкций пользователю.Первоначально мне не удавалось правильно разместить кнопку в правом нижнем углу экрана из-за прокрутки, но это было исправлено здесь: Плавающая кнопка действия поверх прокрутки, застрявшая сверху .Теперь, когда кнопка «плавает» правильно, FindViewById
не может ее найти!Не знаю, что происходит, как я могу это исправить?
