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

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)); } } }
