How to use the effects view in Xamarin.Forms' ListView (SfListView)?
You can integrate the SfEffects in Xamarin.forms SfListView by loading the SfEffectsView as the content of ItemTemplate or SelectedItemTemplate.
Xaml: SfEffectsView added as the content of SelectedItemplate with Scale and Selection effects.
<sync:SfListView x:Name="listView"
AutoFitMode="Height"
SelectionMode="Single"
ItemsSource="{Binding BookInfo}">
<sync:SfListView.SelectedItemTemplate>
<DataTemplate>
<Grid>
<effects:SfEffectsView x:Name="effectsView"
SelectionColor="LightSeaGreen"
FadeOutRipple="True"
RippleAnimationDuration="1000"
IsSelected="True">
<effects:SfEffectsView.Behaviors>
<local:Behavior/>
</effects:SfEffectsView.Behaviors>
<StackLayout>
<Label Text="{Binding BookName}" FontSize="21"
FontAttributes="Bold"/>
<Label Grid.Row="1" Text="{Binding BookDescription}"
FontSize="15"/>
</StackLayout>
</effects:SfEffectsView>
</Grid>
</DataTemplate>
</sync:SfListView.SelectedItemTemplate>
</sync:SfListView>
C#: Programmatically apply effects to the SelectedItem.
public class Behavior : Behavior<SfEffectsView>
{
protected override void OnAttachedTo(SfEffectsView bindable)
{
bindable.SelectionChanged += Bindable_SelectionChanged;
base.OnAttachedTo(bindable);
}
private void Bindable_SelectionChanged(object sender, EventArgs e)
{
Device.BeginInvokeOnMainThread(() =>
{
var effectsView = sender as SfEffectsView;
effectsView.ScaleFactor = 0.85;
effectsView.ApplyEffects(SfEffects.Scale);
});
}
protected override void OnDetachingFrom(SfEffectsView bindable)
{
bindable.SelectionChanged -= Bindable_SelectionChanged;
base.OnDetachingFrom(bindable);
}
}
