Я могу разобрать имя, указав индивидуальный идентификатор в URL-адресе (http://192.168.100.5:84/api/academics/students/1 здесь 1 is id). Обычно, когда я вхожу в систему, ему нужны имя пользователя и пароль, а затем Intent to Next Page.Then у меня есть настройка навигации Ящик, который должен быть динамическим в имени пользователя, поскольку имя пользователя для входа отличается, тогда имя на навигационном ящике должно быть изменено.Анализ данных JSON с использованием идентификатора с помощью Volley?

я путаюсь, что бы логика в домашнем классе, как изменения имени пользователя, то имя на ящик должен изменить , На самом деле гиперссылка должна быть http://192.168.100.5:84/api/academics/students
