Xamarin stacklayout Style.Triggers悬停

Question

我想向该堆栈布局添加一个触发器，以便当用户将鼠标悬停时，背景将改变颜色。我已经尝试过StackLayout.Style和StackLayout.Triggers都遇到运行时错误。

  

对于iSO和Android，有更好的方法吗？

<StackLayout VerticalOptions="Center"
                                x:Name="slCancerType"
                                Grid.Row="0"
                                BackgroundColor="#8cb8e1"
                                Orientation="Horizontal">
                        <StackLayout.Style>
                            <Style TargetType="StackLayout">
                                <Setter Property="BackgroundColor" Value="Blue"/>
                                <Style.Triggers>
                                    <Trigger TargetType="StackLayout" Property="StackLayout.IsMouseOver" Value="True">
                                        <Setter Property="Background" Value="Green" />
                                    </Trigger>
                                </Style.Triggers>
                            </Style>
                        </StackLayout.Style>
                        <StackLayout.GestureRecognizers>

                            </Grid.ColumnDefinitions>
                            <Image Source="icons8-search-filled-50_1.png"
                               Grid.Column="1"
                               VerticalOptions="Center" />
                            <Label Text="Enter Form"
                                   TextColor="White"
                                   LineBreakMode="WordWrap"
                                   Grid.Column="2"
                                   VerticalOptions="FillAndExpand"
                                   VerticalTextAlignment="Center"/>
                        </Grid>
                    </StackLayout>
