Xamarin.Forms: ListView inside StackLayout: How to set height?

With the new BindableLayout feature in Xamarin Forms 3.5 you can easily use the ItemsSource on StackPanel.

So, basically you can write something like this:

<StackLayout BindableLayout.ItemsSource="{Binding list}">
    <BindableLayout.ItemTemplate>
        <DataTemplate>
            ...
        </DataTemplate>
    </BindableLayout.ItemTemplate>
</StackLayout>

You can read more about it here: https://blog.xamarin.com/xamarin-forms-3-5-a-little-bindable-love/

The solution in my case was to put the ListView inside a StackLayout and then put that StackLayout inside the main StackLayout. Then I could set the VerticalOptions = LayoutOptions.FillAndExpand on the inner StackLayout (the one containing the ListView) with the result that the ListView got the space it needed (which of course varies depending on the data).

Here is the main code:

listView.ItemsSource = alternativeCells;
listView.ItemSelected += ListViewOnItemSelected;
var listStackLayout = new StackLayout
{
    VerticalOptions = LayoutOptions.FillAndExpand,
    Orientation = StackOrientation.Vertical
};
listStackLayout.Children.Add(listView);
_stackLayout.Children.Add(listStackLayout);

As you see, I added a new StackLayout with the only purpose of putting the ListView inside it. Then I put that listStackLayout inside the main _stackLayout.
