Android-студия ConstraintLayout проблема изменения размера

0 голосов
/ 25 октября 2019

Я довольно новичок в Android Studio и столкнулся с проблемой с ConstraintLayout. А именно, я пытаюсь сделать свое приложение полностью отзывчивым, и хотя ширина моих компонентов идеально подстраивается под любой размер экрана, я понятия не имею, как настроить высоту таким же образом. Вместо этого мой макет смещается вертикально за пределы экрана.

Я бы хотел, чтобы макет идеально подходил для экрана любого размера.

Рассмотрите возможность использования элемента ScrollView, который содержит ваши элементы ConstraintLayout, я рекомендую использовать один ConstraintLayout, по крайней мере, это необходимо. Я использовал this , когда впервые начал использовать ConstraintLayout, это было очень полезно.

Я думаю, что ваши ограничения не были правильно связаны с представлениями в вашем XML-файле.

Попробуйте, я изменил ваш XML-код. Проверьте это и дайте мне знать.
