Native crash when using SfListView with ffimageloading:CachedImage in Android

[Khanh]

Hi,

I added images into SfListView and when scrolling many times -> crash with different application output.

This 's my code:

<sync:SfListView x:Name="ListViewItem"

                                         BackgroundColor="#eaeaea"

                                         ItemsSource="{Binding ListItem}"

                                         SelectedItem="{Binding ItemSelectedItem}"

                                         AutoFitMode="None"

                                         ItemSize="200"

                                         LoadMoreOption="Manual"

                                         LoadMoreCommand="{Binding LoadMoreItemFromCategoryCommand}"

                                         SelectionBackgroundColor="Transparent"

                                         ScrollStateChanged="ListViewItem_ScrollStateChanged"

                                         FooterSize="{Binding HeightFooterListItems}">

<sync:SfListView.LayoutManager>

</sync:SfListView.LayoutManager>

<sync:SfListView.LoadMoreTemplate>

</sync:SfListView.LoadMoreTemplate>

<sync:SfListView.ItemTemplate>

          <DataTemplate>

         <ffimageloading:CachedImage 

                                                     Grid.Column="0"

                                                     VerticalOptions="Fill"

                                                     HorizontalOptions="Fill"

                                                     Source="{Binding UrlItemImage}"

                                                     Aspect="Fill"

                                                     BackgroundColor="Transparent"

                                                     ErrorPlaceholder="ic_no_image.png"

                                                     IsVisible="{Binding VisibleItemImage}">

                                                <!--BackgroundColor="{Binding BackgroundColor}"-->

                                                <ffimageloading:CachedImage.GestureRecognizers>

                                                    <!--<TapGestureRecognizer Command="{Binding Source={x:Reference SalePage}, Path=BindingContext.OnClickImageItemCommand}"

                                                                      CommandParameter="{Binding }" />-->

                                                    <TapGestureRecognizer Command="{Binding Source={x:Reference SalePage}, Path=BindingContext.PlusQuantityCommand}"

                                                                      CommandParameter="{Binding }" />

                                                </ffimageloading:CachedImage.GestureRecognizers>

              </ffimageloading:CachedImage>

</DataTemplate>

<sync:SfListView.FooterTemplate>

</sync:SfListView.FooterTemplate>

</sync:SfListView>
