张高兴的 UWP 开发笔记：横向 ListView
ListView 默认的排列方向是纵向 ( Orientation="Vertical" ) ，但如果我们需要横向显示的 ListView 怎么办？
Blend for Visual Studio 现在就派上用场了。不只是 ListView ，其他的控件也可以用 Blend 定制你自己的 UI 样式。
下面新建一个项目 "HorizontalListViewDemo" ，用于演示横向 ListView ，解决方案结构如下：( GitHub: https://github.com/ZhangGaoxing/uwp-demo/tree/master/HorizontalListViewDemo )
由于只是一个演示项目，ListView 的绑定数据素材引自 Bob Tabor 的 UWP 入门开发视频 https://mva.microsoft.com/zh-cn/training-courses/-windows-10--14541 。
项目分析
1. MainPage 的结构
MainPage 由两部分组成，一个标题，一个 ListView 。
<Grid Background="Black">
<Grid.RowDefinitions>
<RowDefinition Height="Auto" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<!--标题-->
<StackPanel Margin="15,15,15,0">
<TextBlock Text="Horizontal ListView Demo"
FontSize="30" FontWeight="Bold"
Foreground="White" />
<TextBlock Text="横向 ListView" Foreground="White" />
</StackPanel>
<ListView Name="MyListView" Grid.Row="1" />
</Grid>2. 用 Blend 定制样式
首先右击项目，点击“在 Blend 中设计”。
在“对象和时间线”中找到 "MyListView" ，右击。
在“编辑其他模板”中有 ItemTemplate，ItemContainerStyle，ItemsPanel 三个选项。ItemTemplate 用于数据绑定，数据绑定的模板一般是手写完成，用 Blend 也是可以创建数据绑定模板的。ItemContainerStyle 是容器的样式，说白了就是 ListView 中的 Item 的显示样式，像 Width，Background 等都可以在其中定制。ItemsPanel 是横向 ListView 的关键，ListView 的显示方向就在其中。下面是横向 ListView 的 ItemsPanel xaml代码。
<!--横向布局-->
<ItemsPanelTemplate x:Key="HorizontalItemsPanelTemplate">
<VirtualizingStackPanel Orientation="Horizontal"
VerticalAlignment="Top"
ScrollViewer.HorizontalScrollMode="Enabled"
ScrollViewer.VerticalScrollMode="Disabled"/>
</ItemsPanelTemplate>3. 所有代码
