Question

В основном у меня есть следующий код на моем ItemTemplate

, который переводит элементы в ListView ниже

И всякий раз, когда я перехожу вперед на другую страницу, если я нажимаю назад, весь вид искажается

Этот пример ниже представляет собой мягкий пример искажения, проверьте наличие текста на второй карточке в просмотре списка, пропущены слова, но основной размер макета остается прежним, если экран меньше, он будет резать все намного больше.

Есть кто-нибудькогда-нибудь были проблемы с этим раньше?Это происходит в следующих случаях: я возвращаюсь с другого экрана.Объект добавлен в список из другого списка.

Я перепробовал множество вещей, и это постоянно происходит на Android, насколько я знаю, iOS не содержит ошибок.

Xamarin Forms 3.4.0 список, который я использую, является списком syncfusion.

Редактировать: также происходит в представлении списка xamarin
