如何将 Xamarin Forms Shell 集成到 MvvmCross 设置中 [英] How to integrate Xamarin Forms Shell into an MvvmCross setup

问题描述

我打算将 Xamarin Forms 与 MvvmCross 结合使用.

根据他们的教程、App.cs文件需要添加到项目中:

 公共类 App : MvxApplication{公共覆盖无效初始化(){//Mvx.IoCProvider.RegisterType();RegisterAppStart();}}

那么原来的App.xaml.cs就可以作为MvxFormsApplication类:

公共部分类 FormsApp : MvxFormsApplication{公共 FormsApp(){初始化组件();//DependencyService.Register();MainPage = new AppShell();}}

不幸的是 AppShell.xaml 和 AppShell.xaml.cs 文件添加了很多必要的 UI 设置代码，它最初是由 App.xaml 添加的.cs:

 MainPage = new AppShell();

由于 MvvmCross 接管了整个初始化，我不知道如何集成弹出和其他基本 UI 代码.

如果我像这样将它们放在主视图中:

<FlyoutItem Title=关于"图标=icon_about.png"><ShellContent Route="AboutPage";ContentTemplate="{DataTemplate local:AboutPage}";/></FlyoutItem>

我遇到了一些层次错误:

<块引用>

内容不支持FlyoutItem"类型的值

那么我应该如何将 Shell 集成到 MvvmCross 应用程序中?

解决方案

MvvmCross 目前不支持 Xamarin.forms.Shell.

I intend to use Xamarin Forms with MvvmCross.

According to their tutorial, the App.cs file is required to be added to the project:

 public class App : MvxApplication
  {
    public override void Initialize()
    {
      //Mvx.IoCProvider.RegisterType<ICalculationService, CalculationService>();

      RegisterAppStart<MainViewModel>();
    }
  }

Then the original App.xaml.cs can be used as the MvxFormsApplication class:

public partial class FormsApp : MvxFormsApplication
{
  public FormsApp()
  {
    InitializeComponent();
    //DependencyService.Register<MockDataStore>();
    MainPage = new AppShell();
  }
}

Unfortunately the AppShell.xaml and AppShell.xaml.cs files add a lot of necessary UI setup code and it was originally added by the App.xaml.cs:

 MainPage = new AppShell();

As MvvmCross takes over the entire initialization, I don't know how to integrate the flyout and other basic UI code.

If I put them inside the main view like this:

<views:MvxContentPage.Content>
  <FlyoutItem Title="About" Icon="icon_about.png">
    <ShellContent Route="AboutPage" ContentTemplate="{DataTemplate local:AboutPage}" />
  </FlyoutItem>

I get some hiearchy error:

Content does not support values of type 'FlyoutItem'

So how should I integrate the Shell into the MvvmCross app?

解决方案

MvvmCross does not support Xamarin.forms.Shell as of now.
