Remove navigation bar on Xamarin Forms app with Caliburn.Micro

问题

When using the FormsApplication base class with a brand new Xamarin.Forms app using Caliburn.Micro, I end up with an empty navigation bar at the top of my screen. I assume it's being created by Caliburn.Micro somehow, because an out-of-the-box Xamarin.Forms app doesn't have that.

Is there any way I can use Caliburn.Micro with Xamarin.Forms without this navigation bar?

回答1:

I have not used Caliburn.Micro, but I am assuming that it is wrapping your page with a NavigationPage, as what you describe is what would happen if so.

You should be able to hide that navigation bar by setting a simple attribute in your page like so:

<ContentPage NavigationPage.HasNavigationBar="false"
    ..... >
</ContentPage>

If you are not using XAML pages and doing all of your UI in code instead, then you can do it this way within your page constructor:

NavigationPage.SetHasNavigationBar(this, false);

It works for me:

protected override void OnCreate(Bundle bundle)
{
    base.OnCreate(bundle);
    this.Window.AddFlags(WindowManagerFlags.Fullscreen); // hide the status bar

                // Set our view from the "main" layout resource
    SetContentView(Resource.Layout.Main);

    int uiOptions = (int)Window.DecorView.SystemUiVisibility;

    uiOptions |= (int)SystemUiFlags.LowProfile;
    uiOptions |= (int)SystemUiFlags.Fullscreen;
    uiOptions |= (int)SystemUiFlags.HideNavigation;
    uiOptions |= (int)SystemUiFlags.ImmersiveSticky;

    Window.DecorView.SystemUiVisibility = 
     (StatusBarVisibility)uiOptions;
}

If you are using Xamarin Forms 3.x try this in the constructor

 SetValue(NavigationPage.HasNavigationBarProperty, false);
 InitializeComponent();
