Как использовать код метода вызова в Android Studio Java ⇐ Android

[Anonymous]

У меня вопрос, что я делаю приложение калькулятора. Но я должен повторить код каждого редактирования с помощью (OnTextChanged).
Я хочу написать этот код в другом имени класса, и я использую метод вызова во всех AddTextChangedListener, как?

Код: Выделить всё
