Hi
Lin,To
select the item programmatically, we must assign the underlying object from the
collection to the SelectedItem.
Please refer to the following code snippets for more reference,

public void GenerateInfo()
  {
      Random r = new
  Random();
      for (int i =
  0; i < 20; i++)
      {
          var
  contact = new Contacts(CustomerNames[i], r.Next(720, 799).ToString() + "
  - " + r.Next(3010, 3999).ToString(),i==0 ?
  Color.White:Color.Black);
   
          contact.ContactImage
  = ImageSource.FromResource("ListViewXamarin.Images.Image" +
  r.Next(0, 28) + ".png");
          contactsinfo.Add(contact);
   
          if (i ==
  0)
          {
             
  SelectedItem = contactsinfo[i];
          }
      }
  }
