How to load image asynchronously from URI in Xamarin formats

Here is my current code for loading the image:

System.Uri uri;
System.Uri.TryCreate (imageURI, UriKind.Absolute, out uri);
_companyImage.Source = ImageSource.FromUri (uri);

The problem is that the whole program has to wait for this task to complete, I would like to load the image asynchronously, but I cannot work out how to create the image source asynchronously.

Animate the data asynchronously and assign it to your source as soon as it's done.



System.Uri uri;
System.Uri.TryCreate(imageURI, UriKind.Absolute, out uri);
Task<ImageSource> result = Task<ImageSource>.Factory.StartNew(() => ImageSource.FromUri(uri));
_companyImage.Source = await result;

You can simply set the property Image.Source

to a URI and let Xamarin.Forms do the work for you (behind "Working with Images" in Xamarin. Document Forms ).

Example



var someImage = new Image() {
    Aspect = Aspect.AspectFit,
    Source = ImageSource.FromUri(new Uri("http://xamarin.com/content/images/pages/branding/assets/xamagon.png")),
};

Set your url to the original property or bind it from viewmodel

https://developer.xamarin.com/guides/xamarin-forms/user-interface/images/

<Image Source="yoururl"  Aspect="AspectFill" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand"/>
