如何在頁面頂部顯示滾動按鈕Xamarin.Forms

Question

我是Xamarin.Forms的新手。我需要在頁面頂部顯示滾動按鈕。我在Xamarin.Ios https://developer.xamarin.com/recipes/ios/content_controls/scroll_view/create_a_horizontal_scrolling_button_list/中見過一個例子。 我嘗試這樣做：

<StackLayout Orientation="Horizontal" HeightRequest="90"> 

    <Button Text="Button1" /> 

    <Button Text="Button2" /> 

    <Button Text="Button4" /> 

    <Button Text="Button5" /> 

    <Button Text="Button6" /> 

</StackLayout> 

但與此代碼按鈕佔據整個screen.Should我使用電網的，而不是StackLayout？

Answer 1

設置VerticalOptions="Start"的StackLayout。

<StackLayout Orientation="Horizontal" HeightRequest="90" VerticalOptions="Start"> 
    <Button Text="Button1" /> 
    <Button Text="Button2" /> 
    <Button Text="Button4" /> 
    <Button Text="Button5" /> 
    <Button Text="Button6" /> 
</StackLayout>
