Platform: Xamarin.Forms |
Control: SfListView |
Published Date: April 30, 2020 |
Last Revised Date: April 30, 2020

You can display URI images in SfListView in Xamarin.Forms by loading Image in ItemTemplate.

C#

Defining ContactImage property in Model.

namespace ListViewXamarin
{
    public class Contacts : INotifyPropertyChanged
    {
        private string image;
 
        public string ContactImage
        {
            get { return this.image; }
            set
            {
                this.image = value;
                this.RaisedOnPropertyChanged("ContactImage");
            }
        }
 
        public event PropertyChangedEventHandler PropertyChanged;

        public void RaisedOnPropertyChanged(string _PropertyName)
        {
            if (PropertyChanged != null)
            {
                PropertyChanged(this, new PropertyChangedEventArgs(_PropertyName));
            }
        }
    }
}

C#

Populating ContactImage in ViewModel with URI.

namespace ListViewXamarin
{
    public class ContactsViewModel : INotifyPropertyChanged
    {
        
        public ObservableCollection<Contacts> contactsinfo { get; set; }
 
        public void GenerateInfo()
        {
            Random r = new Random();
            for (int i = 0; i < 40; i++)
            {
                var contact = new Contacts();
                contact.ContactImage = ""; //Your Url goes here
                contactsinfo.Add(contact);
            }
        }
 
        public event PropertyChangedEventHandler PropertyChanged;
 
        public void OnPropertyChanged(string name)
        {
            if (this.PropertyChanged != null)
                this.PropertyChanged(this, new PropertyChangedEventArgs(name));
        }
    }
}

XAML
