Я начинаю разрабатывать android и создаю очень простое приложение, содержащее контент внутри, и вы можете редактировать шрифт и размер содержимого с помощью фрагмента настроек. проблема сталкивается со мной, когда, когда я устанавливал свои настройки шрифтов, он хорошо сохранялся. Я закрываю приложение и возвращаюсь к активности содержимого, и он работает очень хорошо, но когда я возвращаюсь к фрагменту настроек, он возвращает тип шрифта JUST. до значения по умолчанию. Размер шрифта остается на определенном пользователем значении. Это код настройки фрагментаSharedPreferences STRANGE BEHAVIOR
