У меня нет ничего нового в Android, поэтому, пожалуйста, извините мой простой вопрос.Сделать onFocusChange работает для `EdiText` - андроид
Я пытаюсь создать регистрационную форму с тремя простыми полями: полное имя, адрес электронной почты и номер телефона.
мне нужно 2 простых вещей, чтобы сделать:
1) Я хочу, когда пользователь закончил просмотр записи поля ошибка оповещения (editText.setError (ERRMSG)) появляется. Например, когда пользователь вводит следующее поле, если в предыдущем поле есть ошибка, появляется сообщение об ошибке. Где следует вставить функцию? На данный момент я пишу его внутри функции public void afterTextChanged (Editable s), но он показывает ошибку предупреждения, когда пользователь печатает и продолжает отображаться, пока то, что он написал, не соответствует проверке.
2) Если пользователь допустил ошибку в определенном поле и смог ее исправить, я хочу показать поле с положительным значком (например, зеленым отмеченным значком), что означает, что его исправление было принято.
Я использую onFocusChange(), но это не работает для меня. Что я делаю неправильно?
Пожалуйста, расскажите мне мой код и большое спасибо за вашу драгоценную помощь.
