SFListView Swiping is not working in Android

[Divyesh-Bhatt]

I've used SFListView control for showing vertical list of data. In that I have to provide Delete feature on Swipe.
So I have implemented EndSwipeTemplate.

iOS
It is working fine.

Android
Not working at all.

Sample Code

<syncfusion:SfListView
    x:Name="listView"
    AllowSwiping="True"
    ItemsSource="{Binding Contacts}"
    SwipeThreshold="100"
    SwipeOffset="150"
    SelectionMode="Multiple"
    SelectionGesture="LongPress"
    ScrollBarVisibility="Always"
    AutoFitMode="Height">
    <syncfusion:SfListView.ItemTemplate x:DataType="model:Contact">
        <DataTemplate x:Name="EndSwipeTemplate" >
            <VerticalStackLayout >
                <local:ContactCard BindingContext="{Binding Path=.}">
                    <local:ContactCard.GestureRecognizers>
                        <TapGestureRecognizer
                                Command="{Binding Path=BindingContext.CardSelectedCommand,
                                                  Source={Reference Name=_contactCardListPage}}" />
                    </local:ContactCard.GestureRecognizers>
                </local:ContactCard>
            </VerticalStackLayout>
        </DataTemplate>
    </syncfusion:SfListView.ItemTemplate>
    <syncfusion:SfListView.EndSwipeTemplate>
        <DataTemplate>
            <Grid BackgroundColor="#DD0000"
                    x:Name="listViewGrid">
                <Grid.GestureRecognizers>
                    <TapGestureRecognizer
                        Command="{Binding Path=BindingContext.DeleteCommand,
                                            Source={x:Reference listView}}"
                        CommandParameter="{Binding .}" />
                </Grid.GestureRecognizers>
                <Label Text="Delete"
                        TextColor="#FFFFFF"
                        HorizontalOptions="Center"
                        FontSize="Small"
                        VerticalOptions="Center">
                </Label>
            </Grid>
        </DataTemplate>
    </syncfusion:SfListView.EndSwipeTemplate>

</syncfusion:SfListView>

We have checked your requirement , we would like to let you know , we would like to inform you that within the Android platform, touch events are not relayed to the parent view when a child view contains gesture recognizers, as this is standard behavior within the framework. Hence we modified sample with customview, which have gesture and passes the touch to the parent item , Please have look at the sample , Added the customview inside the ItemTemplate , here you can use the GestureRegonizer instead of command in local:ContactCard , Please have a look at the sample and let us know if you have any concerns.

CustomClass.cs

#if ANDROID
    public class CustomContentView : ContentView, ITapGestureListener,IDoubleTapGestureListener,ILongPressGestureListener,ITouchListener
#else
    public class CustomContentView : ContentView
#endif
    {
        public CustomContentView()
        {
#if ANDROID
            this.AddGestureListener(this);
            this.AddTouchListener(this);
#endif
        }
 
        // Invoke SfListView's ItemTapped , ItemDoubleTapped and ItemLongPress events through ContentView gestures since,
        // touch won't passes to parent view in Android platform when child view has gesture recognizers.
        void ITapGestureListener.OnTap(TapEventArgs e)
        {
            var parent = this.GetParent(this);
            if (parent is ListViewItem)
            {
                (parent as ListViewItem).OnTap(e);
            }
        }
 
        void ITouchListener.OnTouch(Syncfusion.Maui.Core.Internals.PointerEventArgs e)
        {
           
            var parent = this.GetParent(this);
            if (parent is ListViewItem)
            {
                (parent as ListViewItem).OnTouch(e);
            }
        }
 
        void IDoubleTapGestureListener.OnDoubleTap(TapEventArgs e)
        {
            var parent = this.GetParent(this);
            if (parent is ListViewItem)
            {
                (parent as ListViewItem).OnDoubleTap(e);
            }
        }
 
        void ILongPressGestureListener.OnLongPress(LongPressEventArgs e)
        {
            var parent = this.GetParent(this);
            if (parent is ListViewItem)
            {
                (parent as ListViewItem).OnLongPress(e);
            }
       }
 
        internal object GetParent(object currentView)
        {
            while (currentView != null && currentView.GetType() != typeof(ListViewItem))
            {
                return this.GetParent((currentView as Element).Parent);
            }
 
            return currentView;
        }
    }

In XAML

<syncfusion:SfListView x:Name="listView" Grid.Row="1" ScrollBarVisibility="Never" 
ItemSize="60"
AllowSwiping="True"
BackgroundColor="#FFE8E8EC"
ItemsSource="{Binding ToDoList}"

This is a problem still as of 28.2.7. I would be nice if this issue could be fixed officially or at least mentioned in the guide: https://help.syncfusion.com/maui/listview/swiping

However, this workaround does work. You need to be careful to not allow any touch events on the controls that go inside the CustomContentView or else the CustomContentView won't get the touch events, either.
