xaml - Windows 8 Metro::什么是 AutomationProperties.AutomationId 和 AutomationProperties.Name

正如你在下面的代码中看到的，我从微软示例中得到

<SemanticZoom.ZoomedOutView>
    <tiles:VariableTileControl  x:Name="SemanticItemGridView"
                                AutomationProperties.AutomationId="itemGridView"
                                AutomationProperties.Name="Grouped Items"
                                Padding="80,87,10,0"
                                ItemsSource="{Binding Source={StaticResource SemanticgroupedItemsViewSource}}"

                                Margin="0,0,0,-13"

            </GroupStyle>
        </GridView.GroupStyle>
    </GridView>
</SemanticZoom.ZoomedInView>

在上面的代码中，我只对如下所示的一行感兴趣
AutomationProperties.AutomationId="itemGridView"

AutomationProperties.Name="分组项目"

我想知道上面提到的行在 xaml 中的作用是什么。

最佳答案

编辑:

例如，在 Visual Studio 中，如果您创建新的 Windows 应用商店网格应用，请查看 GroupedItemsPage.xaml。您会看到一些设置了 AutomationProperties.Name 的地方。

现在打开 Windows 8 Charms Bar 并搜索“Narrator”，然后运行结果中出现的 Narrator 应用程序。你会听到一个男人开始在屏幕上读东西。

如果您返回到 Visual Studio 并运行您创建的新网格应用程序，讲述人将读取网格应用程序中的各种内容，其中一些将是在 xaml 中定义的 AutomationProperties.Names。

尝试更改 AutomationProperties.Name 以了解其工作原理。
