Question

首先，我是WPF的初学者，所以请用简单的词语解释。

我想制作包含很多元素的自定义列表视图项。我决定使用网格来很好地对齐它。不幸的是，当我试图查看是否所有内容都正在调整时，背景（listview项目）调整大小而网格不是。我认为这是因为网格没有正确附加到listview项目。所以问题是我如何将网格附加到listview项目，以便我可以正确地缩放内容？

这是代码（由于我试图解决问题，它有点乱）：

Answer 1

这就是你需要的东西

在列表视图中添加此样式资源，并从网格中删除宽度。

    <ListView BorderThickness="0"
                Height="440">
        <ListView.Resources>
            <Style TargetType="ListViewItem">
                <Setter Property="Template">
                    <Setter.Value>
                        <ControlTemplate TargetType="ListViewItem">
                            <Border Background="{TemplateBinding Background}">
                                <ContentPresenter />
                            </Border>
                        </ControlTemplate>
                    </Setter.Value>
                </Setter>
            </Style>
        </ListView.Resources>

通过从列表视图项修改默认teplate将使内容重新调整大小

也删除以下内容

<ListView.View>
    <GridView>
        <GridViewColumn/>
    </GridView>
</ListView.View>

Answer 2

ListView通常使用如下：

使用绑定：

<ListView BorderThickness="0" >
      <ListView.View>
              <GridView>
                 <GridViewColumn Header="Name" Width="200" DisplayMemberBinding="{Binding Name}"/>
                 <GridViewColumn Header="Address" Width="200" DisplayMemberBinding="{Binding Address}"/>
               </GridView>
</ListView.View>

或者像这样：

 <ListView BorderThickness="0" >
     <ListViewItem>
          <Grid >
             ....
          </Grid>
      </ListViewItem>
  </ListView>

您确定需要同时设置ListView.View和ListViewItem吗？它看起来像： enter image description here

顺便说一句，你不应该设置网格的宽度和高度，最重要的是你的网格内容看起来很混乱。你必须在正确的Grid.Col或Grid.Row中设置这些标签，为什么你设置ColumnSpan / RowSpan？如果你确定它是正确的？
