Как перенести сообщение о подтверждении или passwordToggle в android

Если вы посмотрите на изображение, вы увидите, что значок проверки мешает значку passwordToggle. Есть ли способ переместить значок проверки или значок пароля?

Answer 1

Ну я не знаю, если это единственный способ передать le, но для того, чтобы обойти это, я переключил свой макет с линейного макета на макет Grid и добавил свой СОБСТВЕННЫЙ значок NEXT в поле пароля и создал слушателя для изображения, чтобы сделать то же самое. Однако при переходе к сетке, кажется, что теперь я потерял проверки значок ошибки, я задал этот вопрос здесь, мы надеемся, получите ответ на него: https://stackoverflow.com/questions/39290052/android-validation-icon-does-not-appear

Picture of NEW look

изменения кода были следующими
strings.xml не нужно было изменять.
Внедрение схемы сетки вместо этого и добавление отдельных изображений, которые были бы СЛЕДУЮЩИМ в поля пароля.
