You will have to add a custom view cell where you can set the on click colour:
In your PCL:
Add a custom ViewCell something like this:
public class ExtendedViewCell : ViewCell
{
public static readonly BindableProperty SelectedBackgroundColorProperty =
BindableProperty.Create("SelectedBackgroundColor", typeof(Color), typeof(ExtendedViewCell), Color.Default);
public Color SelectedBackgroundColor
{
get { return (Color)GetValue(SelectedBackgroundColorProperty); }
set { SetValue(SelectedBackgroundColorProperty, value); }
}
}
In your, Android Project add the following:
public class ExtendedViewCellRenderer : ViewCellRenderer
{
private Android.Views.View _cellCore;
private Drawable _unselectedBackground;
private bool _selected;
protected override Android.Views.View GetCellCore(Cell item, Android.Views.View convertView, ViewGroup parent, Context context)
{
try
{
_cellCore = base.GetCellCore(item, convertView, parent, context);
_selected = false;
_unselectedBackground = _cellCore.Background;
return _cellCore;
}
catch(Exception ex)
{
AppLogger.LogException(ex);
return null;
}
}
protected override void OnCellPropertyChanged(object sender, PropertyChangedEventArgs args)
{
try
{
base.OnCellPropertyChanged(sender, args);
if (args.PropertyName == "IsSelected")
{
_selected = !_selected;
if (_selected)
{
var extendedViewCell = sender as ExtendedViewCell;
_cellCore.SetBackgroundColor(extendedViewCell.SelectedBackgroundColor.ToAndroid());
}
else
{
_cellCore.SetBackground(_unselectedBackground);
}
}
}
catch(Exception ex)
{
AppLogger.LogException(ex);
}
}
}
Similarly for iOS something like below:
public class ExtendedViewCellRenderer : ViewCellRenderer
{
public override UITableViewCell GetCell(Cell item, UITableViewCell reusableCell, UITableView tv)
{
try
{
var cell = base.GetCell(item, reusableCell, tv);
var view = item as ExtendedViewCell;
cell.SelectedBackgroundView = new UIView
{
BackgroundColor = view.SelectedBackgroundColor.ToUIColor(),
};
cell.SelectionStyle = UITableViewCellSelectionStyle.None;
return cell;
}
catch(Exception ex)
{
AppLogger.LogException(ex);
return null;
}
}
}
Now do not forget to add the custom renderer header on the native Classes above the namespace
[assembly: ExportRenderer(typeof(ExtendedViewCell), typeof(ExtendedViewCellRenderer))]
Now all you have to do is replace your above ViewCell with this controls view cell and pass the SelectedBackgroundProperty.
In your case it will look like this:
<ListView x:Name="Llist"
ItemTapped="Lista_ItemTapped" >
<ListView.ItemTemplate>
<DataTemplate>
<nameSpace:ExtendedViewCell SelectedBackgroundColor="White">
<StackLayout BackgroundColor="{Binding color}">
<Label Text="{Binding name}"/>
<Label Text="{Binding age}"/>
<Label Text="{Binding sex}"/>
</StackLayout>
</nameSpace:ExtendedViewCell>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
