uwp win10 Listview SelectedItem样式

Question

有没有办法在选择这个时更改ListviewItem的属性？

作为一个例子,我希望ListviewItem中的一个矩形在选中时为红色,默认为蓝色.

如何以优雅的方式实现这一目标？

您可以设置ListView.ItemContainerStyle自定义中ListViewItems使用的样式ListView.

此页面显示默认样式:https://msdn.microsoft.com/en-us/library/windows/apps/mt299136.aspx

如果是您的示例 - 您将Selected~Background在代码中更改类似于以下内容的属性:

<ListView ...>
    <ListView.ItemContainerStyle>
        <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="{ThemeResource SystemControlHighlightListAccentLowBrush}"
          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>
