Hi Nilmer, 
 
We would like to let you know that we have achieved your requirement “Swap image by program” using button click event as like below code snippet. 
 
Behavior.cs 
public class Behavior : Behavior<ContentPage> 
{ 
   Button Swap; 
   SfListView ListView; 
   Random random = new Random(); 
   protected override void OnAttachedTo(ContentPage bindable) 
   { 
      Swap = bindable.FindByName<Button>("button"); 
      ListView = bindable.FindByName<SfListView>("listView"); 
      Swap.Clicked += Swap_Clicked; 
      base.OnAttachedTo(bindable); 
   } 
 
   private void Swap_Clicked(object sender, EventArgs e) 
   { 
      var contact = new Model(); 
      contact.Image = ImageSource.FromResource("SfListViewSamples.Images.Image" + random.Next(0, 19) + ".png"); 
      (ListView.BindingContext as ViewModel).ContactsInfo[0] = contact; 
   } 
} 
 
We have attached the tested sample for your reference, please find the sample in the below link. 
 
 
Please let us know whether the provided sample meets your requirement.
