Hi Divyesh Bhatt,

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.

Code snippet:

#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}"

DragStartMode="OnDragIndicator,OnHold"

ItemTapped="listView_ItemTapped"

SelectionMode="None">

 

<syncfusion:SfListView.ItemTemplate>

<DataTemplate>

<local:CustomContentView>

<local:CustomContentView.GestureRecognizers>

<TapGestureRecognizer Tapped="TapGestureRecognizer_Tapped"/>

</local:CustomContentView.GestureRecognizers>

<Grid x:Name="rootGrid" Padding="10" BackgroundColor="Beige">

<Label  Text="{Binding Name}"/>

</Grid>

</local:CustomContentView>

</DataTemplate>

</syncfusion:SfListView.ItemTemplate>

Please let us know if you have any queries.
