如何停用 GridViewItem点击动画（如下所示），右击一个GridViewItem？

GridViewItem-click animation

修改
Nate建议后的代码（不起作用）。我添加了VisualStates，但我仍然看到动画。但是，所选项目不再具有蓝色边框，因为我添加了VisualStateGroup元素（我不关心，但代码有一些效果）。

为了仅对右键单击进行操作，您可能必须制作一个自定义控件，该控件在右键单击时不会触发指针按下状态更改，但在左键单击时会执行。 < / p>

下一部分是针对left- 和的右键点击：

根据您当前的Xaml，有两件事要尝试。

在GridViewItem default styles and templates中有两个内容模板，一个使用GridViewItemPresenter，另一个不使用。{/ p>

首先，尝试使用GridViewItemPresenter样式，但使用新的ContentTransitions覆盖TransitionCollection属性。

<!-- Default style for Windows.UI.Xaml.Controls.GridViewItem -->
<Style TargetType="GridViewItem">
    <Setter Property="FontFamily" Value="{ThemeResource ContentControlThemeFontFamily}" />
    <Setter Property="FontSize" Value="{ThemeResource ControlContentThemeFontSize}" />
    <Setter Property="Background" Value="Transparent"/>
    <Setter Property="TabNavigation" Value="Local"/>
    <Setter Property="IsHoldingEnabled" Value="True"/>
    <Setter Property="Margin" Value="0,0,2,2"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="GridViewItem">
                <GridViewItemPresenter
                    Padding="{TemplateBinding Padding}"
                    SelectionCheckMarkVisualEnabled="True"
                    CheckHintBrush="{ThemeResource ListViewItemCheckHintThemeBrush}"
                    CheckSelectingBrush="{ThemeResource ListViewItemCheckSelectingThemeBrush}"
                    CheckBrush="{ThemeResource ListViewItemCheckThemeBrush}"
                    DragBackground="{ThemeResource ListViewItemDragBackgroundThemeBrush}"
                    DragForeground="{ThemeResource ListViewItemDragForegroundThemeBrush}"
                    FocusBorderBrush="{ThemeResource ListViewItemFocusBorderThemeBrush}"
                    PlaceholderBackground="{ThemeResource ListViewItemPlaceholderBackgroundThemeBrush}"
                    PointerOverBackground="{ThemeResource ListViewItemPointerOverBackgroundThemeBrush}"
                    SelectedBorderThickness="{ThemeResource GridViewItemCompactSelectedBorderThemeThickness}"
                    SelectedBackground="{ThemeResource ListViewItemSelectedBackgroundThemeBrush}"
                    SelectedForeground="{ThemeResource ListViewItemSelectedForegroundThemeBrush}"
                    SelectedPointerOverBackground="{ThemeResource ListViewItemSelectedPointerOverBackgroundThemeBrush}"
                    SelectedPointerOverBorderBrush="{ThemeResource ListViewItemSelectedPointerOverBorderThemeBrush}"
                    DisabledOpacity="{ThemeResource ListViewItemDisabledThemeOpacity}"
                    DragOpacity="{ThemeResource ListViewItemDragThemeOpacity}"
                    ReorderHintOffset="{ThemeResource ListViewItemReorderHintThemeOffset}"
                    HorizontalContentAlignment="{TemplateBinding HorizontalContentAlignment}"
                    VerticalContentAlignment="{TemplateBinding VerticalContentAlignment}"
                    PointerOverBackgroundMargin="1"
                    ContentMargin="4" >
                    <GridViewItemPresenter.ContentTransitions>
                        <TransitionCollection/>
                    </GridViewItemPresenter.ContentTransitions>
                </GridViewItemPresenter>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

如果仍然无效，请在同一页面上使用下面的样式。完全放在这里太长了，所以我刚为VisualStateGroup添加了固定的CommonStates。如果你去了我上面链接的地方，滚动到底部的部分，然后将其全部复制，然后折叠并覆盖CommonStates VisualStateGroup块，它应该有效。

<VisualStateGroup x:Name="CommonStates">
    <VisualState x:Name="Normal"/>
    <VisualState x:Name="PointerOver">
        <Storyboard>
            <DoubleAnimation Storyboard.TargetName="PointerOverBorder"
                             Storyboard.TargetProperty="Opacity"
                             Duration="0"
                             To="1" />
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SelectionBackground"
                                            Storyboard.TargetProperty="Fill">
                <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ListViewItemSelectedPointerOverBackgroundThemeBrush}" />
            </ObjectAnimationUsingKeyFrames>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SelectedBorder"
                                            Storyboard.TargetProperty="Stroke">
                <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ListViewItemSelectedPointerOverBorderThemeBrush}" />
            </ObjectAnimationUsingKeyFrames>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SelectedEarmark"
                                           Storyboard.TargetProperty="Fill">
                <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ListViewItemSelectedPointerOverBackgroundThemeBrush}" />
            </ObjectAnimationUsingKeyFrames>
        </Storyboard>
    </VisualState>
    <VisualState x:Name="Pressed">
        <Storyboard/>
    </VisualState>
    <VisualState x:Name="PointerOverPressed">
        <Storyboard>
            <DoubleAnimation Storyboard.TargetName="PointerOverBorder"
                             Storyboard.TargetProperty="Opacity"
                             Duration="0"
                             To="1" />
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SelectionBackground"
                                            Storyboard.TargetProperty="Fill">
                <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ListViewItemSelectedPointerOverBackgroundThemeBrush}" />
            </ObjectAnimationUsingKeyFrames>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SelectedBorder"
                                            Storyboard.TargetProperty="Stroke">
                <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ListViewItemSelectedPointerOverBorderThemeBrush}" />
            </ObjectAnimationUsingKeyFrames>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetName="SelectedEarmark"
                                           Storyboard.TargetProperty="Fill">
                <DiscreteObjectKeyFrame KeyTime="0" Value="{ThemeResource ListViewItemSelectedPointerOverBackgroundThemeBrush}" />
            </ObjectAnimationUsingKeyFrames>
        </Storyboard>
    </VisualState>
    <VisualState x:Name="Disabled">
        <Storyboard>
            <DoubleAnimation Storyboard.TargetName="contentPresenter"
                             Storyboard.TargetProperty="Opacity"
                             Duration="0"
                             To="{ThemeResource ListViewItemDisabledThemeOpacity}" />
        </Storyboard>
    </VisualState>
</VisualStateGroup>

希望这有助于编码！
