静态创建按钮时，清除和添加stacklayout没有问题，但是动态创建按钮时，清除和添加stacklayout就有问题了。
在动态创建的时候有什么需要我单独做的吗？我也必须在代码中创建布局本身吗？
我不明白。这就像一只虫子。

<ContentView x:Name="xMainContentsView" Grid.Row="1" Grid.Column="0" HorizontalOptions="FillAndExpand" VerticalOptions="FillAndExpand">

            <ScrollView Orientation="Horizontal" HorizontalOptions="FillAndExpand">
                <StackLayout x:Name="xView" Margin="35,80,35,80" Spacing="25" Orientation="Horizontal" HorizontalOptions="FillAndExpand">
                    <Button Text="g02" Clicked="Button_Clicked"></Button>                   
                </StackLayout>
            </ScrollView>
            
            <!--<StackLayout x:Name="xPageView"  Orientation="Horizontal" HorizontalOptions="FillAndExpand">
            </StackLayout>-->
</ContentView>

private void Button_Clicked(object sender, EventArgs e)
        {
            xView.Children.Clear();
            xView.Children.Add(new Spectrum(this));
        }



private void InitializeCompView()
        {
              
            foreach (MainViewMeasureType contents in Enum.GetValues(typeof(MainViewMeasureType)))
            {
                CtrlButton button = new CtrlButton
                {
                    WidthRequest = 180,
                    HeightRequest = 180,
                    Text = contents.ToString(),
                    ClassId = contents.ToString(),
                };
                button.Pressed += BtnMainContentClick;

                xView.Children.Add(button);
            } 
        }
        


private void BtnMainContentClick(object sender, EventArgs e)
        {
            xView.Children.Clear();
            xView.Children.Add(new Spectrum(this));
        }
