如何更改ListView项中的背景颜色
本文关键字:背景 颜色 何更改 ListView | 更新日期: 2023-09-27 18:25:46
我是使用MVVM构建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,行应该是黄色的。
我有没有的代码:
<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>
这个代码帮助我在选择行时更改背景颜色。此外,我还有绑定到SelectedIndex的属性。
当我点击这一行的图像时,如何使这一行成为黄色背景?
感谢
测试此代码也许有效:
<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(应该有效)
<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 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>
