我正在开发窗口商店应用程序。我有一个按钮，它使用如下定义的样式：

<Style x:Key="MyButtonStyle" TargetType="ButtonBase">
    <Setter Property="Content" Value="ms-appx:///image1.png"/>
</Style>

如果我的按钮对焦，我可以显示image2.png而不是image1.png吗？我正在使用Windows应用商店应用程序，因此此处不支持触发器。我应该在这里使用视觉状态管理器吗？

您想要设置焦点视觉样式，请参考此答案以获取示例：

根据您的描述，我发现您有两个要求，一个要求是将图像设置为按钮的内容，另一个要求是在按钮聚焦时将按钮的内容更改为另一个图像

要求1：将图像设置为按钮的内容

我看到您使用了以下样式将图像设置为按钮的内容：

直接使用代码不能将图像设置为按钮的内容，为了实现它，我们需要将图像控件放在按钮的模板中

PS：由于您使用的是Windows应用商店应用程序，我将以Windows 8.1应用商店应用程序为例，以供以后参考，UWP应用程序的情况几乎相同。

我们可以通过在XAML中创建按钮并右键单击按钮控件-->“编辑模板”->“编辑副本…”来获取按钮的模板，如下所示：

  <ContentPresenter x:Name="ContentPresenter" AutomationProperties.AccessibilityView="Raw" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
       <Image Name="MyImage" Source="{TemplateBinding Content}"></Image>
  </ContentPresenter>

       <Style x:Key="OriginalButtonStyle" TargetType="Button">

  <Style x:Key="MyButtonStyle" TargetType="Button" BasedOn="{StaticResource OriginalButtonStyle}">

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Button x:Name="button" Style="{StaticResource MyButtonStyle}"  HorizontalAlignment="Left" Margin="100,100,100,100" />
</Grid>

然后，它将向我们显示按钮控件的默认样式，名称为：OriginalButtonStyle，之后请查找ContentPresenter，并在其中添加图像控件，如下所示：

        <Setter Property="BorderBrush" Value="{ThemeResource ButtonBorderThemeBrush}"/>

        <Setter Property="Padding" Value="12,4,12,4"/>
        <Setter Property="HorizontalAlignment" Value="Left"/>
        <Setter Property="VerticalAlignment" Value="Center"/>

                                    <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Source" Storyboard.TargetName="MyImage">
                                            <DiscreteObjectKeyFrame KeyTime="0" Value="ms-appx:///image1.png"/>
                                    </ObjectAnimationUsingKeyFrames>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <Border x:Name="Border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Margin="3">
                            <ContentPresenter x:Name="ContentPresenter" AutomationProperties.AccessibilityView="Raw" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}">
                                <Image Name="MyImage" Source="{TemplateBinding Content}"></Image>
                            </ContentPresenter>
                        </Border>
                        <Rectangle x:Name="FocusVisualWhite" IsHitTestVisible="False" Opacity="0" StrokeDashOffset="1.5" StrokeEndLineCap="Square" Stroke="{ThemeResource FocusVisualWhiteStrokeThemeBrush}" StrokeDashArray="1,1"/>
                        <Rectangle x:Name="FocusVisualBlack" IsHitTestVisible="False" Opacity="0" StrokeDashOffset="0.5" StrokeEndLineCap="Square" Stroke="{ThemeResource FocusVisualBlackStrokeThemeBrush}" StrokeDashArray="1,1"/>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>

  <Style x:Key="MyButtonStyle" TargetType="Button" BasedOn="{StaticResource OriginalButtonStyle}">
        <Setter Property="Content" Value="ms-appx:///image1.png"/>
    </Style>


<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Button x:Name="button" Style="{StaticResource MyButtonStyle}"  HorizontalAlignment="Left" Margin="100,100,100,100" />
</Grid>

之后，如果我们将按钮的内容设置为ImageURL/Soruce的值，例如：ms-appx:///image1.png，它将图像显示为按钮的内容

要求2：当按钮聚焦时，将按钮内容更改为另一个图像。

请在按下的焦点上找到这些指针聚焦的VisualState，并逐个添加以下XAML，因为当按钮进入聚焦状态时，将触发这些VisualState：

<ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Source" Storyboard.TargetName="MyImage"> <DiscreteObjectKeyFrame KeyTime="0" Value="ms-appx:///image2.png "/> </ObjectAnimationUsingKeyFrames>

因此，按钮的整个样式：原始按钮样式将如下所示：

<ContentPresenter x:Name="ContentPresenter" AutomationProperties.AccessibilityView="Raw" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <Image Name="MyImage" Source="{TemplateBinding Content}"></Image> </ContentPresenter>

注意： 所有上述更改均在原始按钮样式中进行，为了使用您的MyButtonStyle，我们可以从原始按钮样式继承MyButtonStyle，如下所示：

<ContentPresenter x:Name="ContentPresenter" AutomationProperties.AccessibilityView="Raw" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"> <Image Name="MyImage" Source="{TemplateBinding Content}"></Image> </ContentPresenter>

在那之后，它工作得很好
