Xaml 在UWP应用程序中设置所有ListViewItem的样式

我想更改

ListViewItem

的选定背景色。现在我注意到，默认值不会被覆盖

<Style TargetType="ListViewItem">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="ListViewItem">
                <ListViewItemPresenter
                  ContentTransitions="{TemplateBinding ContentTransitions}"
                  SelectionCheckMarkVisualEnabled="True"
                  CheckBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}"
                  CheckBoxBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}"
                  DragBackground="{ThemeResource ListViewItemDragBackgroundThemeBrush}"
                  DragForeground="{ThemeResource ListViewItemDragForegroundThemeBrush}"
                  FocusBorderBrush="{ThemeResource SystemControlForegroundAltHighBrush}"
                  FocusSecondaryBorderBrush="{ThemeResource SystemControlForegroundBaseHighBrush}"
                  PlaceholderBackground="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}"
                  PointerOverBackground="{ThemeResource SystemControlHighlightListLowBrush}"
                  PointerOverForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}"
                  SelectedBackground="{StaticResource YellowBrush}"
                  SelectedForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}"
                  SelectedPointerOverBackground="{ThemeResource SystemControlHighlightListAccentMediumBrush}"
                  PressedBackground="{ThemeResource SystemControlHighlightListMediumBrush}"
                  SelectedPressedBackground="{ThemeResource SystemControlHighlightListAccentHighBrush}"
                  DisabledOpacity="{ThemeResource ListViewItemDisabledThemeOpacity}"
                  DragOpacity="{ThemeResource ListViewItemDragThemeOpacity}"
                  ReorderHintOffset="{ThemeResource ListViewItemReorderHintThemeOffset}"
                  HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"
                  VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
                  ContentMargin="{TemplateBinding Padding}"
                  CheckMode="Inline"/>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

但是我只想设置

ListViewItem

的样式，而不影响其他样式

编辑：

因为我有

Visual Studio需要更新版本的WIndows来显示此内容。请更新到Windows 10周年纪念版（10.0.14393.0）或更高版本

我将目标版本设置为10240。这是我在创建Thomas Schneiter所述副本后在App.xaml中发现的：

<Application.Resources>

        <Setter Property="Template">
            <Setter.Value>

                        CheckBrush="{ThemeResource SystemControlForegroundBaseMediumHighBrush}"

                        DragForeground="{ThemeResource ListViewItemDragForegroundThemeBrush}"

                        DragBackground="{ThemeResource ListViewItemDragBackgroundThemeBrush}" 
                        DisabledOpacity="{ThemeResource ListViewItemDisabledThemeOpacity}"
                        FocusBorderBrush="{ThemeResource SystemControlForegroundAltHighBrush}" 
                        FocusSecondaryBorderBrush="{ThemeResource SystemControlForegroundBaseHighBrush}"
                        HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}" 
                        PointerOverForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}" 
                        PressedBackground="{ThemeResource SystemControlHighlightListMediumBrush}" 
                        PlaceholderBackground="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}" 
                        PointerOverBackground="{ThemeResource SystemControlHighlightListLowBrush}" 
                        ReorderHintOffset="{ThemeResource ListViewItemReorderHintThemeOffset}" 
                        SelectedPressedBackground="{ThemeResource SystemControlHighlightListAccentHighBrush}" 
                        SelectionCheckMarkVisualEnabled="True" 
                        SelectedForeground="{ThemeResource SystemControlHighlightAltBaseHighBrush}" 
                        SelectedPointerOverBackground="{ThemeResource SystemControlHighlightListAccentMediumBrush}" 
                        SelectedBackground="{ThemeResource SystemControlHighlightListAccentLowBrush}" 
                        VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"/>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</Application.Resources>

现在我尝试覆盖

SelectedBackground

，但更改没有得到应用。

您可以右键单击Designer视图中的任何列表视图，然后选择

编辑其他模板

->

编辑生成的项目容器（项目容器样式）

->

编辑副本

---

然后选择

Apply to all

和

Application

自动将全局副本插入app.xaml。

将

ItemContainerStyle

的副本添加到你的app.xaml资源中，无需密钥即可使其成为你的应用程序的默认副本。你能发布链接到

ItemContainerStyle

的副本吗？我找不到，除了。似乎您正在使用xamarin.form，并使用xamarin的

ListView

控件？你解决这个问题了吗？@GraceFeng-MSFT：是的，没错。不，我还没解决。我想到了以下几种选择：1。创建一个自定义主题（看起来很粗糙）。2.创建自定义渲染器（但仅针对一个平台？）3。尝试覆盖事件，如

ItemSelected

，并从那里更改背景颜色。但我必须为每个

列表视图
执行此操作。理想情况下，我可以使用问题中所述的样式，但该样式不适用……现在我创建了您所述的副本（请参见我编辑的问题），但该样式不适用。我相信这是因为没有创建
ItemContainerStyle
元素？如果我将
SelectedBackground
更改为另一种颜色，它将应用于应用程序中的所有列表视图。
ItemContainerStyle
属性应该从
ListView
中删除，以使用全局定义的样式。现在，我从中尝试了该示例，背景确实得到了应用，但在我的实际应用程序中没有。我也尝试运用我最初的风格，在这里它也起作用。也许是一个框架问题（Xamarin.Forms）。了解更多信息后，我将提供一些信息。使用
ItemContainerStyle
可以定义Listview项的周围容器。
DataTemplate
用于在此容器中排列数据。可能您的
DataTemplate
中的控件有背景色，因此您看不到ItemContainer的背景？如何查找“DataTemplate”中的内容？树可视化工具？
