我有一个TabbedPage，有3个孩子。在xamarin.forms中使用XAML的选项卡式页面内容页面
public partial class FactoryDetailsTabs : TabbedPage
{
public FactoryDetailsTabs()
{
InitializeComponent();
Children.Add(new FactoryDetailsTabs_DashboardTab());
Children.Add(new FactoryDetailsTabs_AnalysisTab());
Children.Add(new FactoryDetailsTabs_SettingsTab());
}
}
第3个选项卡包含设置页面。随着代码
<?xml version="1.0" encoding="utf-8" ?>
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"

xmlns:controls="clr-namespace:LogicalSugarDemoApp.NativeModels"
Title="Settings" Icon="settings">

<Picker x:Name="LanguagePicker"

</RelativeLayout>
</Frame>
</RelativeLayout>
<controls:AdView HorizontalOptions="Center" VerticalOptions="EndAndExpand"/>
</ContentPage>
我没有得到任何输出在第三页页面内的选项卡。但是，当我在TabbedPage之外的内容页面中执行此代码时可以使用。请帮忙。我需要它在TabbedPage内
你能与里面的一些水鸭线分享一下你要在两种不同的情况，COS我越来越粉红色显示的屏幕截图，我不知道tabbedpage。 – Dilmah
