How to swipe the Xamarin.Forms ListView item while tapping (SfListView)?
The Xamarin.Forms SfListView allows you to swipe the ListViewItem in ItemTapped event. When swiping the item programmatically in the ItemTapped event, the touch handles the selection if Selection is enabled for SfListView and the next touch is handled for the swipe. You can also achieve this requirement by skipping the selection as mentioned in the following three ways.
Method 1:
XAML
Disable selection for SfListView by using SelectionMode as None. In this case, by tapping on one item, the tapped item will be swiped and tapping another item will reset the swiped item.
<syncfusion:SfListView x:Name="listView" SelectionMode="None" ItemSize="60" AllowSwiping="True" ItemsSource="{Binding ContactsInfo}">
<syncfusion:SfListView.ItemTemplate >
<DataTemplate>
<Grid x:Name="grid">
...
</Grid>
</DataTemplate>
</syncfusion:SfListView.ItemTemplate>
<syncfusion:SfListView.LeftSwipeTemplate>
<DataTemplate>
<Grid BackgroundColor="Teal">
<Label Text="Left swipe template" HorizontalOptions="Center" VerticalOptions="Center" LineBreakMode="NoWrap"/>
</Grid>
</DataTemplate>
</syncfusion:SfListView.LeftSwipeTemplate>
</syncfusion:SfListView>
C#
In the ItemTapped event, swipe the ListViewItem using the SfListView.SwipeItem method.
namespace ListViewXamarin
{
public class Behavior : Behavior<ContentPage>
{
SfListView ListView;
protected override void OnAttachedTo(ContentPage bindable)
{
ListView = bindable.FindByName<SfListView>("listView");
ListView.ItemTapped += ListView_ItemTapped;
base.OnAttachedTo(bindable);
}
private void ListView_ItemTapped(object sender, Syncfusion.ListView.XForms.ItemTappedEventArgs e)
{
ListView.SwipeItem(e.ItemData, ListView.SwipeOffset);
}
}
}
Method 2:
C#
Set Handled property of the ItemTappedEventArgs as true to handle the touch by ItemTapped event. In this case, the touch will not be passed to the selection process. Also, taping another item will reset the swiped item.
namespace ListViewXamarin
{
public class Behavior : Behavior<ContentPage>
{
SfListView ListView;
protected override void OnAttachedTo(ContentPage bindable)
{
ListView = bindable.FindByName<SfListView>("listView");
ListView.ItemTapped += ListView_ItemTapped;
base.OnAttachedTo(bindable);
}
private void ListView_ItemTapped(object sender, Syncfusion.ListView.XForms.ItemTappedEventArgs e)
{
ListView.SwipeItem(e.ItemData, 200);
e.Handled = true;
}
}
}
Method 3:
XAML
You can use GestureRecongnizers for ItemTemplate to swipe the ListViewItem. In this case, the gestures will handle the touch instead of the ListViewItem. Thus, on each interaction, the tapped item is swiped.
<syncfusion:SfListView x:Name="listView" SwipeOffset="200" ItemSize="60" AllowSwiping="True" ItemsSource="{Binding ContactsInfo}">
<syncfusion:SfListView.ItemTemplate >
<DataTemplate>
<Grid x:Name="grid">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="70" />
<ColumnDefinition Width="*" />
</Grid.ColumnDefinitions>
<Grid.GestureRecognizers>
<TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"/>
</Grid.GestureRecognizers>
<Image Source="{Binding ContactImage}" VerticalOptions="Center" HorizontalOptions="Center" HeightRequest="50" WidthRequest="50"/>
<Grid Grid.Column="1" RowSpacing="1" Padding="10,0,0,0" VerticalOptions="Center">
<Label LineBreakMode="NoWrap" TextColor="#474747" Text="{Binding ContactName}"/>
<Label Grid.Row="1" Grid.Column="0" TextColor="#474747" LineBreakMode="NoWrap" Text="{Binding ContactNumber}"/>
</Grid>
</Grid>
</DataTemplate>
</syncfusion:SfListView.ItemTemplate>
<syncfusion:SfListView.LeftSwipeTemplate>
<DataTemplate>
<Grid BackgroundColor="Teal">
<Label Text="Left swipe template" HorizontalOptions="Center" VerticalOptions="Center" LineBreakMode="NoWrap"/>
</Grid>
</DataTemplate>
</syncfusion:SfListView.LeftSwipeTemplate>
</syncfusion:SfListView>
C#
namespace ListViewXamarin
{
public partial class MainPage : ContentPage
{
public MainPage()
{
InitializeComponent();
}
private void TapGestureRecognizer_Tapped(object sender, EventArgs e)
{
var currentItem = (sender as Grid).BindingContext as Contacts;
listView.SwipeItem(currentItem, listView.SwipeOffset);
}
}
}
