what I want to achieve is a bit complex but I always get the exception in the subject.
My goal is to create a page having a SfPopupLayout, a SfNavigationDrawer and a SfListView nested in another SfListView. If I create the page piece by piece, starting from the nested SfListView, I can compile and view the result until I put the last step, despite what this step is: SfListView + SfListView + SfNavigationDrawer works, SfListView + SfListView + SfPopupLayout works, SfListView + SfListView + SfNavigationDrawer + SfPopupLayout doesn't work, SfListView + SfListView + SfPopupLayout + SfNavigationDrawer doesn't work.

The listviews read data from a SQLite database and everything is binded in MVVM pattern.

Here's the relevant part of my code:

<sfPopup:SfPopupLayout x:Name="popUpLayout" HorizontalOptions="FillAndExpand" IsOpen="{Binding IsOpenAlert, Mode=TwoWay}" VerticalOptions="FillAndExpand">
<sfPopup:SfPopupLayout.Content HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">
<navigationdrawer:SfNavigationDrawer x:Name="navigationDrawer" BackgroundColor="{StaticResource AppBackgroundColor}" DrawerHeaderHeight="200" DrawerWidth="300" HorizontalOptions="FillAndExpand" IsOpen="{Binding IsOpen, Mode=TwoWay}" VerticalOptions="FillAndExpand">
<Grid BackgroundColor="{StaticResource AppBackgroundColor}">
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<ColumnDefinition Width="*" />
<ColumnDefinition Width="Auto" />
<StackLayout Margin="0" Padding="0" HorizontalOptions="FillAndExpand" Orientation="Horizontal" VerticalOptions="FillAndExpand">
<Button />
<Label />
<StackLayout Grid.Column="1" Margin="0" Padding="0" HorizontalOptions="FillAndExpand" Orientation="Horizontal" VerticalOptions="FillAndExpand">
<Button />
<Button />
<Button />
<listView:SfListView x:Name="listView" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="2" Margin="0,20,0,0" AutoFitMode="Height" ItemsSource="{Binding ListaStati}" Loaded="ListView_Loaded">
<Grid Margin="0,0,0,15">
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
<StackLayout Margin="0" Padding="20,0,0,0" HorizontalOptions="FillAndExpand" Orientation="Horizontal" VerticalOptions="FillAndExpand">
<Image Aspect="AspectFit" Source="{Binding Immagine}" VerticalOptions="CenterAndExpand" />
<Label Margin="10,0,0,0" FontAttributes="Bold" FontSize="Medium" Text="{Binding DescStato}" VerticalOptions="CenterAndExpand" VerticalTextAlignment="Center" />
<ctrl:ExtendedListView Grid.Row="1" AutoFitMode="Height" HeightRequest="{Binding InnerListHeight}" ItemSize="200" ItemsSource="{Binding Audits}" Orientation="Horizontal" SelectionMode="SingleDeselect">
<local:AuditViewTabletMode />
<local:PopUpLogout AcceptButtonText="{i18n:Translate Text=ConfirmButtonText}" AcceptCommand="{Binding AcceptButtonCustomCommand}" DeclineButtonText="{i18n:Translate Text=CancelButtonText}" DeclineCommand="{Binding DeclineButtonCustomCommand}" />

The ExtendedListView class is taken from one of your examples (here)

How can I achieve the result?

Thanks in advance,

Hi Matteo,  
Thanks for Contacting Syncfusion Support. 
We have checked the reported query “Java.Lang.StackOverflowError” from our side. We have prepared the sample based on the template given by you and checked the issue. Unfortunately, the reported crash does not replicate at our end. Listview is loaded in the view as expected.    
We have attached the tested sample for your reference and you can download the same from the below link.    
Can you please check the reported issue occurs in our sample also? If not, we would request you to modify our sample to replicate the issue which would highly help us to analyze the query better and provide an appropriate solution.

I think I solved it, thanks.
I'm waiting for a physical Android device to arrive and I will test it there.
