Xamarin Forms Master Detail页面包含在父页面中

Question

I have a simple master detail page, but for some reason the master page seems to be contained within the detail view. In other words, the menu starts where the detail navigation bar ends -- I would expect the master page to start at the top of the screen. What's the deal?

    public class MasterPage : MasterDetailPage
    {
        public MasterPage(Sdk.Application context)
        {
            Title = "Master Page";

            this.Master = new MenuPage();
            this.Detail = DetailPage();

            IsPresented = true;
        }            
    }


    private NavPage DetailPage()
    {
        var result = new NavPage(new BasePage { Title = "Empty" });

        ... populate page content ...

        return result;
    }

Answer 1

You must set on Android Proyect in your main Activity use AppCompat instead of FormsApplicationActivity so you see the Master get over the navigation bar:

public class MainActivity : FormsAppCompatActivity

Here is a great blog post on how to achieve that!

Answer 2

That is the standard behavior for Android. https://developer.xamarin.com/guides/xamarin-forms/user-interface/navigation/master-detail-page/
