Xamarin.Forms - 从主页查看缺少的菜单

Question

我创建了这个运行良好的菜单，但在某些打开的页面上不使用菜单，它被替换为后退按钮。无论如何要确保菜单在所有页面上？

主页.xaml

<MasterDetailPage.Detail>

        <NavigationPage>

            <x:Arguments>

                <pages:HomePage />

            </x:Arguments>

        </NavigationPage>

    </MasterDetailPage.Detail>

主页.xaml.cs

 var masterDetailPage = Application.Current.MainPage as MasterDetailPage;

        masterDetailPage.Detail = new NavigationPage((new SearchPage("A")));
