Пользователь в данный момент нажимает на строку, которая содержит данные и отображается диалог с текстовыми полями.
Я хочу, чтобы пользователь обновлял строки с помощью этого диалога.

Как я могу это сделать?

У меня есть метод обновления уже в моем классе базы данных, но я не уверен, как реализовать обновление в диалоге
