Xamarin.Forms Android StackOverflowError與TabbedPage

我面臨的問題與Xamarin.Forms和更特別與Android上的TabbedPage。Xamarin.Forms Android StackOverflowError與TabbedPage

我創建了一個包含4個ContentPage的TabbedPage。每個ContentPage都包含一個帶有自定義ItemTemplate的ListView（XAML中超過50行）。它在iOS上，但不是在Android上工作的很好，我收到此異常：

在谷歌的一些研究之後，我發現這個同樣的問題https://forums.xamarin.com/discussion/48144/stackoverflowerror-on-android但解決辦法不能在我的情況（我不能降低應用我的itemtemplate的行數）。不過，我不知道這個問題的根源是在ItemTemplate元素的數量，因爲相同ContentPage在MasterDetailPage正常工作在Android

如果我不能使用TabbedPage，你知道一個組件/示例，我可以用它在Xamarin.Forms中創建一個TabBar。

非常感謝您的幫助。此致敬禮。 Olivier。

你正在測試什麼設備/模擬器？你能把你的代碼放在什麼地方，所以我們可以嘗試重現嗎？ –

@YuriS感謝您的回答。我發現我的問題，它出現在我們在NavigationPage內創建一個TabbedPage。我認爲我們無法創建包含TabbedPage的導航頁面。它適用於iOS，但不適用於Android。最好爲TabbedPage的每個子頁面創建一個NavigationPage。 Thx – user1317878

我有這個相同的錯誤，並通過減少我的listview項目模板上的佈局元素的數量來解決它。我建議使用帶有行和列的網格來使你的佈局更有效率。 –

當我在TabbedPage中將ListView包裝在ScrollView中時，我遇到了同樣的問題。您需要從此佈局中刪除ScrollView。因爲ListView有其自己的內部滾動
