Я столкнулся с проблемой с Xamarin.Forms и более подробно с TabbedPage на Android.Xamarin.Forms Android StackOverflowError с TabbedPage
Я создал вкладку, содержащую 4 ContentPage. Каждый ContentPage содержит ListView с пользовательским ItemTemplate (более 50 строк в XAML). Это работает отлично на прошивке, но не на Android, и я получил это исключение:
Java.Lang.StackOverflowError:

После некоторых исследований на Google я нашел этот же вопрос https://forums.xamarin.com/discussion/48144/stackoverflowerror-on-android, но обходной путь не может быть применен в моем случае (я не могу уменьшить количество строк моей itemtemplate). Однако я не уверен, что источником проблемы является количество элементов в ItemTemplate, потому что тот же ContentPage отлично работает в MasterDetailPage на Android
Если я не могу использовать TabbedPage, вы знаете компонент/который я могу использовать для создания TabBar в Xamarin.Forms.
Заранее благодарю вас за помощь. С уважением. Olivier.
Какое устройство/симулятор вы тестируете? Можете ли вы поместить свой код где-нибудь, чтобы мы могли попытаться воспроизвести? –
@YuriS Благодарим вас за ответ. Я нашел свою проблему, она появляется, когда мы создаем TabbedPage внутри NavigationPage. Я думаю, что мы не можем создать страницу навигации, содержащую TabbedPage. Он работает на iOS, но не на Android. Желательно создать NavigationPage для каждой дочерней страницы моего TabbedPage. Thx – user1317878
i имел ту же ошибку и исправил ее, уменьшив количество элементов макета на моем элементе списка listview. Я предлагаю использовать сетки с rowspan и columnspan, чтобы сделать ваши макеты более эффективными. –
