C# ListView项控件模板触发器未触发

我有一个包含GridView的ListView。我正在尝试更改选定项目的背景和悬停项目的背景。经过一些搜索，我发现了控制模板和触发器，但它们没有触发

这是我的意思的截图

非常感谢您的帮助。谢谢

您设置了

ControlTemplate

，但没有任何子控件来显示数据。您需要修改的样式是

ListViewItem

，而不是

ListBoxItem

您可以这样做：

<ListView x:Name="TestListView" Margin="0,0.333,0.333,0" Grid.Row="1" Grid.Column="1" SelectedIndex="0" SelectionMode="Single" Background="#FF181818" Foreground="White" BorderBrush="#FF181818">
    <ListView.Resources>
        <Style TargetType="{x:Type ListViewItem}">
            <Style.Triggers>
                <Trigger Property="IsMouseOver" Value="True">
                    <Setter Property="Background" Value="Red"/>
                </Trigger>
                <Trigger Property="IsSelected" Value="True">
                    <Setter Property="Background" Value="Blue" />
                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.Resources>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="A" Width="120" DisplayMemberBinding="{Binding A}" />
            <GridViewColumn Header="B" Width="50" DisplayMemberBinding="{Binding B}" />
            <GridViewColumn Header="C" Width="150" DisplayMemberBinding="{Binding C}" />
            <GridViewColumn Header="D" Width="150" DisplayMemberBinding="{Binding D}" />
        </GridView>
    </ListView.View>
</ListView>

<ListView x:Name="TestListView" Margin="0,0.333,0.333,0" Grid.Row="1" Grid.Column="1" SelectedIndex="0" SelectionMode="Single" Background="#FF181818" Foreground="White" BorderBrush="#FF181818">
    <ListView.Resources>
        <Style TargetType="{x:Type ListViewItem}">

                <Trigger Property="IsMouseOver" Value="True">

                </Trigger>
                <Trigger Property="IsSelected" Value="True">

                </Trigger>
            </Style.Triggers>
        </Style>
    </ListView.Resources>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="A" Width="120" DisplayMemberBinding="{Binding A}" />
            <GridViewColumn Header="B" Width="50" DisplayMemberBinding="{Binding B}" />
            <GridViewColumn Header="C" Width="150" DisplayMemberBinding="{Binding C}" />
            <GridViewColumn Header="D" Width="150" DisplayMemberBinding="{Binding D}" />
        </GridView>
    </ListView.View>
</ListView>
