Question

我是使用MVVM建立Windows Phone应用程序的新手。

我的任务是：

当我选择行时，它应该是蓝色背景。在每一行我都有图像，当我点击图像时，行应该是黄色。

我的代码为no：

    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="Template">
                <Setter.Value>
                    <ControlTemplate TargetType="ListViewItem">
                        <Grid>
                            <VisualStateManager.VisualStateGroups>
                                <VisualStateGroup x:Name="CommonStates">
                                    <VisualState x:Name="Normal"/>
                                </VisualStateGroup>
                                <VisualStateGroup x:Name="SelectionStates">
                                    <VisualState x:Name="Unselected">
                                        <Storyboard>
                                            <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="White"/>
                                        </Storyboard>
                                    </VisualState>
                                    <VisualState x:Name="SelectedUnfocused">
                                        <Storyboard>
                                            <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="LightBlue"/>
                                        </Storyboard>
                                    </VisualState>
                                </VisualStateGroup>
                            </VisualStateManager.VisualStateGroups>
                            <Border x:Name="myback" Background="Transparent">
                                <ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
                            </Border>
                        </Grid>
                    </ControlTemplate>
                </Setter.Value>
            </Setter>
        </Style>
    </ListView.ItemContainerStyle>

此代码可帮助我在选择行时更改背景颜色。我也有绑定到SelectedIndex的属性。

当我点击此行的图像时如何为行创建黄色背景？

谢谢

测试此代码也许可以工作：

 <ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListViewItem">
                    <Grid Background="Yellow">
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal"/>
                            </VisualStateGroup>
                            <VisualStateGroup x:Name="SelectionStates">
                                <VisualState x:Name="Unselected">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="White"/>
                                    </Storyboard>
                                </VisualState>
                                <VisualState x:Name="SelectedUnfocused">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="LightBlue"/>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <Border x:Name="myback" Background="Transparent">
                            <ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ListView.ItemContainerStyle>

尝试此代码（应该可以使用）

        <ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <Setter Property="Template">
            <Setter.Value>
                <ControlTemplate TargetType="ListViewItem">
                    <Grid>
                        <VisualStateManager.VisualStateGroups>
                            <VisualStateGroup x:Name="CommonStates">
                                <VisualState x:Name="Normal"/>
                            </VisualStateGroup>
                            <VisualStateGroup x:Name="SelectionStates">
                                <VisualState x:Name="Unselected">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="Blue"/>
                                    </Storyboard>
                                </VisualState>
                                <VisualState x:Name="SelectedUnfocused">
                                    <Storyboard>
                                        <ColorAnimation Duration="0" Storyboard.TargetName="myback" Storyboard.TargetProperty="(Border.Background).(SolidColorBrush.Color)" To="Yellow"/>
                                    </Storyboard>
                                </VisualState>
                            </VisualStateGroup>
                        </VisualStateManager.VisualStateGroups>
                        <Border x:Name="myback" Background="Transparent">
                            <ContentPresenter Content="{TemplateBinding Content}" ContentTemplate="{TemplateBinding ContentTemplate}"/>
                        </Border>
                    </Grid>
                </ControlTemplate>
            </Setter.Value>
        </Setter>
    </Style>
</ListView.ItemContainerStyle>
