Xamarin Native 到 Forms 的转换

Question

I am working with the Xamarin forms app that uses native camera. I am trying to switch from Forms to Native and then back to forms based on https://github.com/supreettare/Forms2Native2Forms/blob/master/FormsBasics.Android/FormsActivity.cs

in Android: SetPage (App.GetSecondPage ());

in Forms:

public static Page GetSecondPage ()
    {
        var formsPage = new NavigationPage (new MyThirdPage ()); 

        return formsPage;
    }

My concern is when I call this function it gives me android.view.InflateException: Binary XML file line #1: Error inflating class .

If I do SetPage(new GetSecondPage()), I can navigate to the other page but then can not use Navigation.PushAsync() anywhere on that page.

Have you tried to use Page.CreateSupportFragment method ?

In your activity,you could load the page which defined in your forms like

protected override void OnCreate(Bundle bundle)
{
    base.OnCreate(bundle);
    Forms.Init(this, bundle);
    SetContentView(Resource.Layout.Main);          
    Android.Support.V4.App.Fragment mainPage = YourPage.CreateSupportFragment(this);
    SupportFragmentManager
        .BeginTransaction()
        .Replace(Resource.Id.fragment_frame_layout, mainPage)
        .Commit();

}

you could refer to Nativie Forms
