试试这个
通过将 ListView 高度设置为 Itemtemplate(网格)。
<ListView x:Name="MyImageList">
<ListView.ItemContainerStyle>
<Style TargetType="ListViewItem">
<Setter Property="HorizontalContentAlignment" Value="Stretch" />
<Setter Property="VerticalContentAlignment" Value="Stretch" />
</Style>
</ListView.ItemContainerStyle>
<ListView.ItemsPanel>
<ItemsPanelTemplate>
<StackPanel Orientation="Horizontal" />
</ItemsPanelTemplate>
</ListView.ItemsPanel>
<ListView.ItemTemplate>
<DataTemplate>
<Grid Height="{Binding ElementName=MyImageList,Path=ActualHeight}">
<Grid.RowDefinitions>
<RowDefinition Height="4*" />
<RowDefinition Height="*" />
</Grid.RowDefinitions>
<Image Grid.Row="0" Source="Screenshot_3.png" Stretch="UniformToFill" />
<Label Grid.Row="1" Content="fghfgh" />
</Grid>
</DataTemplate>
</ListView.ItemTemplate>
</ListView>
更新
通过设置 VerticalScrollBarVisibility="Hidden" 或禁用并添加边距可以解决此问题,但正确的解决方案如下
这个垂直滚动条的出现是由于 Listview 和 ListviewItem 默认样式中的默认边距和填充..您可以通过编辑 listview 和 listviewItem 的样式来获得所需的结果
工作示例(没有垂直滚动条)
