xmlns:local="clr-namespace:xxx"
x:Class="xxx.MainPage">
<MasterDetailPage.Master>

<NavigationPage>
<x:Arguments>
<local:Pages.LoginPage></local:Pages.LoginPage>
</x:Arguments>
</NavigationPage>

</MasterDetailPage>

Main Page.axml.cs

public partial class MainPage : MasterDetailPage
{
public MainPage()
{
InitializeComponent();
MasterBehavior = MasterBehavior.Popover;//new
MasterPage.listView.ItemSelected += OnItemSelected;
Master = MasterPage;
NavigationPage page = new NavigationPage(new Pages.LoginPage());
page.BarBackgroundColor = Color.FromHex("#29B6F6");
Detail = page;
}
private void OnItemSelected(object sender, SelectedItemChangedEventArgs e)
{
var item = e.SelectedItem as ClassFiles.MasterPageItem;
if (item!=null)
{
Page displayPage = (Page)Activator.CreateInstance(item.TargetType);
NavigationPage page = new NavigationPage(displayPage);
page.BarBackgroundColor = Color.FromHex("#29B6F6");
Detail = page;
//Detail = new NavigationPage((Page)Activator.CreateInstance(item.TargetType));
MasterPage.listView.SelectedItem = null;
IsPresented = false;
}
}
}
