Xamarin.forms listview中的ScrollView工作不正常

我把一个滚动视图放在一个列表视图中，它不能正常工作；它有时会卡住。我更改了VerticalOptions属性，但它会滚动移动，然后卡住

这是我的标记：

<ListView RowHeight="70" ItemTapped="ListView_ItemTapped" Margin="15,10" HasUnevenRows="True"  SeparatorVisibility="None" ItemsSource="{Binding InteractionsHistory}">
<ListView.ItemTemplate>
    <DataTemplate>
        <ViewCell >
            <StackLayout BackgroundColor="White"  
                                     Orientation="Horizontal" 
                                     HorizontalOptions="FillAndExpand" 
                                     VerticalOptions="FillAndExpand"
                                     Margin="0,0,0,10">
                <Grid  HorizontalOptions="FillAndExpand" RowSpacing="1" Margin="0,5,0,0">
                    <Grid.RowDefinitions>
                        <RowDefinition Height="25" />
                        <RowDefinition Height="1" />
                        <RowDefinition Height="100"/>
                        <RowDefinition Height="1" />
                        <RowDefinition Height="30" />
                    </Grid.RowDefinitions>
                    <StackLayout  Grid.Row="0" Orientation="Horizontal" Margin="5,0,5,0" >
                        <local:ImageCircle Aspect="AspectFill" VerticalOptions="Center" Source="{Binding ChannelImg}"  WidthRequest="25" HeightRequest="25"/>
                        <Label Text="{Binding InteractionAddedBy}" Style="{StaticResource lblCommonVewCase}" HorizontalOptions="FillAndExpand"/>
                        <Label Text="{Binding CreatedDate}" HorizontalOptions="EndAndExpand" Style="{StaticResource lblCommonVewCase}"/>
                    </StackLayout>
                    <StackLayout Margin="5,0,5,0" Style="{StaticResource CommonStackLayout}" Grid.Row="1"></StackLayout>
                    <ScrollView  Margin="10,10,10,0" Grid.Row="2"  VerticalOptions="Fill" Orientation="Vertical" HorizontalOptions="Fill" BackgroundColor="AliceBlue" >
                        <Label  Text="{Binding InteractionDesc}" VerticalOptions="FillAndExpand" Style="{StaticResource lblCommonVewCase}"/>
                    </ScrollView>
                    <StackLayout Margin="5,0,5,0" IsVisible="{Binding IsAttachmentVisible}"  Style="{StaticResource CommonStackLayout}" Grid.Row="3"></StackLayout>
                    <StackLayout Grid.Row="4" VerticalOptions="Center" Orientation="Horizontal" Margin="15,0" Padding="0,5" 
                                                 IsVisible="{Binding IsAttachmentVisible}" BackgroundColor="White">
                        <Image Source="attach.png" HeightRequest="15" WidthRequest="15" VerticalOptions="Center"/>
                        <Label Text="Attachments" Style="{StaticResource lblCommonVewCase}" VerticalOptions="Center"/>
                        <StackLayout.GestureRecognizers>
                            <TapGestureRecognizer Tapped="ViewAttach_Tapped" CommandParameter="{Binding .}"></TapGestureRecognizer>
                        </StackLayout.GestureRecognizers>
                    </StackLayout>
                </Grid>
            </StackLayout>
        </ViewCell>
    </DataTemplate>
</ListView.ItemTemplate>
</ListView>

您不应该将ListView放在ScrollView中，因为ListView类实现了自己的滚动，并且不接收手势，因为它们都由父ScrollView处理

即使在本机平台开发中，也不鼓励这样做。

在ListView中使用ScrollView或其他方式是非常不鼓励的，因为这样会导致奇怪的行为，如下面所示。我建议你另找一种方法来解决你的问题。好的，谢谢你宝贵的时间，先生
