问Xamarin中的ListView inside StackLayout不会基于列表视图项目高度进行扩展

EN

<ContentPage.Content>
        <StackLayout>    
            <StackLayout Orientation="Vertical" VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand" >
                <ListView
                  HasUnevenRows="True"  
                  ItemsSource="{Binding sampleList}"
                  CachingStrategy="RecycleElement">
                    <ListView.ItemTemplate>
                        <DataTemplate>
                            <ViewCell>
                              <views:sampleView/>
                            </ViewCell>
                        </DataTemplate>
                    </ListView.ItemTemplate>
                </ListView>
            </StackLayout>         
        </StackLayout>        
</ContentPage.Content>   

 1) Setting the Height Request to parent Stack Layout. 

         It worked for some devices and not worked for some devices. 

 2) Use Grid instead of StackLayout by setting the Grid row definitions like given below.                         `<Grid.RowDefinitions>                 <RowDefinition Height="*"></RowDefinition>             </Grid.RowDefinitions>`              But this change also didn't fix the issue.

 3) Use Scroll View instead of StackLayout 

         This will work. But Xamarin suggests we should not nest ScrollView with other controls that provide scrolling, like ListView and WebView.
