Как новичок для Android, я пытаюсь создать образец приложения - зарегистрируйтесь и войдите. Я использую Android Studio!Проблема проверки в Android
Всякий раз, когда я нажимаю кнопку «Регистрация», в «Закусочной панели» отображаются «Эй, все поля обязательны!» несмотря на заполнение всех полей!
И ниже приведен код, предназначенный для регистрации.

В чем Ваш вопрос? – Rami
Всякий раз, когда я нажимаю кнопку «Регистрация», в «Закусочной панели» отображаются «Привет, все поля обязательны!» несмотря на заполнение всех полей! –
