Xamarin.Forms implement AndHud and BTProgressHud

问题

Can anyone point me to a Xamarin.forms sample that utilises AndHud for Android and BTProgressHud for iOS (or anything similar)?

I know there is the ACR-Xamarin-Forms example here https://github.com/aritchie/acr-xamarin-forms, but it is way too complicated and completely over my head.

Surely there is a more simple easy to understand implementation, but if not some sort of guidance on how to get started on implementing it (for a C# and Xamarin newbie)

Thanks in advance

This is how I've done it for iOS. All you should need to do for Android is create an implementation of IHud that using AndHud instead of BTProgressHud.

First, create an interface in the shared project

public interface IHud
{
    void Show();
    void Show(string message);
    void Dismiss();
}

Next, in the iOS project, create an implementation of IHud using BTProgressHud component:

[assembly: Dependency(typeof(Hud))]
namespace project.iOS
{
    public class Hud : IHud
    {
        public Hud ()
        {
        }

        public void Show() {
            BTProgressHUD.Show ();
        }

        public void Show(string message) {
            BTProgressHUD.Show (message);
        }

        public void Dismiss() {
            BTProgressHUD.Dismiss ();
        }
    }
}

Finally, to utilize this from Forms code, just do

    var hud = DependencyService.Get<IHud> ();
    hud.Show ("Loading Vehicles");

    // tasks...

    hud.Dismiss ();
