Xaml Xamarin表单将一个内容页绑定到另一个内容页

我正在尝试将1

ContentPage

.cs绑定（组合）到另一个

ContentPage

xaml页面。但是我错过了一些东西

<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="Class1" Title=""
             xmlns:local="clr-namespace:namespace;assembly:assembly">
    <ContentPage.Content>
        <StackLayout>
        <StackLayout Orientation="Vertical">
            <Label Text="Select Refering Physician" HorizontalOptions="CenterAndExpand"
                  TextColor="Aqua" FontSize="20">
                <Label.GestureRecognizers>
                    <TapGestureRecognizer Tapped="Handle_Handle" NumberOfTapsRequired="1" >
                    </TapGestureRecognizer>
                </Label.GestureRecognizers>
            </Label>
            <ContentView x:Name="overlay"
                 AbsoluteLayout.LayoutBounds="0, 0, 1, 1"
                 AbsoluteLayout.LayoutFlags="All"
                 IsVisible="False"
                 BackgroundColor="#C0808080"
                 Padding="10, 0">
                <StackLayout Orientation="Vertical" 
                   BackgroundColor="White" 
                   HorizontalOptions="Center" 
                   VerticalOptions="Start" 
                   Margin="0,20,0,0" >
                    <Label BackgroundColor="Black" FontSize="18" TextColor="White" HorizontalOptions="Fill" Text="Search a user" />
                </StackLayout>
            </ContentView>
        </StackLayout>
            <StackLayout>
                <local:ListviewPage>
                </local:ListviewPage>                  
            </StackLayout>
        </StackLayout>
    </ContentPage.Content>
</ContentPage>

这门课是我要学的

 public class ListviewPage : ContentPage
    {
        ObservableCollection<ListViewModel> ListItems { get; set; } = new ObservableCollection<ListViewModel> {
            new ListViewModel{Text = "Item 1"},
            new ListViewModel{Text = "Item 2"},
            new ListViewModel{Text = "Item 3"},
            new ListViewModel{Text = "Item 4"},
            new ListViewModel{Text = "Item 5"},
            new ListViewModel{Text = "Item 6"},
            new ListViewModel{Text = "Item 7"},
            new ListViewModel{Text = "Item 8"},
            new ListViewModel{Text = "Item 9"}
        };

        ListView ListView { get; set; }

        public ListviewPage()
        {
            ListView = new ListView();
            ListView.ItemsSource = ListItems;
            ListView.ItemTemplate = new DataTemplate(typeof(CustomCell));
            ListView.ItemTapped += MenuListView_ItemTapped;

            var ListViewLayout = new StackLayout();
            ListViewLayout.Padding = new Thickness(10, 20);
            ListViewLayout.Children.Add(ListView);
            Content = ListViewLayout;
        }

        void MenuListView_ItemTapped(object sender, ItemTappedEventArgs e)
        {
            if ((sender as ListView).SelectedItem == null)
                return;
            (sender as ListView).SelectedItem = null;

            var item = e.Item as ListViewModel;
            if (item.IsSelected)
                item.IsSelected = false;
            else
                item.IsSelected = true;
        }
    }

我不想导航我想在同一个页面中呈现它

我认为你要做的应该是使用一个单独的视图/控件，它可以在多个页面中使用，而不是试图将页面放在页面中

    public class ListViewControl : StackLayout
    {
        ObservableCollection<ListViewModel> ListItems { get; set; } = new ObservableCollection<ListViewModel> 
        {
            new ListViewModel{Text = "Item 1"},
            new ListViewModel{Text = "Item 2"},
            new ListViewModel{Text = "Item 3"},
            new ListViewModel{Text = "Item 4"},
            new ListViewModel{Text = "Item 5"},
            new ListViewModel{Text = "Item 6"},
            new ListViewModel{Text = "Item 7"},
            new ListViewModel{Text = "Item 8"},
            new ListViewModel{Text = "Item 9"}
        };

        ListView ListView { get; set; }

        public ListViewControl()
        {
            ListView = new ListView();
            ListView.ItemsSource = ListItems;
            ListView.ItemTemplate = new DataTemplate(typeof(CustomCell));
            ListView.ItemTapped += MenuListView_ItemTapped;

            //NOTE: this is where you would want to set any bindings,
            //either in code or by adding a xaml file to do it in there instead.

            Padding = new Thickness(10, 20);
            Children.Add(ListView);
        }

        void MenuListView_ItemTapped(object sender, ItemTappedEventArgs e)
        {
            if ((sender as ListView).SelectedItem == null)
                return;
            (sender as ListView).SelectedItem = null;

            var item = e.Item as ListViewModel;
            if (item.IsSelected)
                item.IsSelected = false;
            else
                item.IsSelected = true;
        }
    }

然后在

RadShedulerDiagnosis

页面中使用该新类，在页面或视图上设置BindingContext，并在xaml

中使用新控件

尝试创建新的内容页并将代码复制到该页。这是最简单的方法

我认为这是不可能的。即使是这样，我相信这不是一种方式，它看起来会像标签页那样。不管怎样，我想在这种情况下，a对你来说是更好的方法，不是吗？

    public class ListViewControl : StackLayout
    {
        ObservableCollection<ListViewModel> ListItems { get; set; } = new ObservableCollection<ListViewModel> 
        {
            new ListViewModel{Text = "Item 1"},
            new ListViewModel{Text = "Item 2"},
            new ListViewModel{Text = "Item 3"},
            new ListViewModel{Text = "Item 4"},
            new ListViewModel{Text = "Item 5"},
            new ListViewModel{Text = "Item 6"},
            new ListViewModel{Text = "Item 7"},
            new ListViewModel{Text = "Item 8"},
            new ListViewModel{Text = "Item 9"}
        };

        ListView ListView { get; set; }

        public ListViewControl()
        {
            ListView = new ListView();
            ListView.ItemsSource = ListItems;
            ListView.ItemTemplate = new DataTemplate(typeof(CustomCell));
            ListView.ItemTapped += MenuListView_ItemTapped;

            //NOTE: this is where you would want to set any bindings,
            //either in code or by adding a xaml file to do it in there instead.

            Padding = new Thickness(10, 20);
            Children.Add(ListView);
        }

        void MenuListView_ItemTapped(object sender, ItemTappedEventArgs e)
        {
            if ((sender as ListView).SelectedItem == null)
                return;
            (sender as ListView).SelectedItem = null;

            var item = e.Item as ListViewModel;
            if (item.IsSelected)
                item.IsSelected = false;
            else
                item.IsSelected = true;
        }
    }
