PanGestureRecognizer is not working in Android

[VishalOmprasad]

Description

We have added a simple Grid layout in the MainPage with PanGestureRecognizer. We have added Frame as the Grid's child element. Upon panning the PanUpdated event is not getting triggered.

• Windows (Working)

PanGesture-Windows.mp4

• Android (not working)

PanGesture-Android.mp4

Steps to Reproduce

1. Add a Grid layout to your MainPage’s content.
2. Add PanGestureRecognizer to the Grid layout.
3. Hook the PanGestureRecognizer.PanUpdated event.
4. Run the sample and do swipe/pan action.
5. Notice that the PanUpdated event will not be called.

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="GridTouchTest.MainPage">

    <Grid BackgroundColor="Red">
        <Grid.GestureRecognizers>
            <PanGestureRecognizer PanUpdated="PanGestureRecognizer_PanUpdated" />
        </Grid.GestureRecognizers>
        <Frame x:Name="getStartedFrame"
               Margin="0"
               Padding="0"
               Background="#10556C"
               BorderColor="Transparent"
               CornerRadius="10"
               HorizontalOptions="FillAndExpand"
               Opacity="0.7"
               VerticalOptions="FillAndExpand"
               HasShadow="False" />
    </Grid>
</ContentPage>

[C#]

public partial class MainPage : ContentPage
    {
        public MainPage()
        {
            InitializeComponent();
        }

        private void PanGestureRecognizer_PanUpdated(object sender, PanUpdatedEventArgs e)
        {

        }
    }
