c# - C# UWP ListView 移除所有视觉效果

问题描述

在 UWP 中，我有一个列表视图。

XAML： 

 <Grid Background="Gray">
    <ListView Name="lvMain" VerticalAlignment="Top" HorizontalAlignment="Stretch" Height="120" ItemsSource="{x:Bind ItemsList, Mode=OneWay}">
        <ListView.ItemsPanel>
            <ItemsPanelTemplate>
                <ItemsStackPanel Orientation="Horizontal"/>
            </ItemsPanelTemplate>
        </ListView.ItemsPanel>
        <ListView.ItemTemplate>
            <DataTemplate x:DataType="x:Int32">
                <Grid Width="100" Height="100" Padding="10">
                    <Grid Background="Green"/>
                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</Grid>

在后面的代码中：

using System.Collections.ObjectModel;
using Windows.UI.Xaml.Controls;

public sealed partial class MainPage : Page
{
    public ObservableCollection<int> ItemsList { get; set; } = new ObservableCollection<int>();

    public MainPage()
    {
        InitializeComponent();

        for (int i = 0; i < 10; i++)
        {
            ItemsList.Add(i);
        }
    }
}

结果如下：

那么项目之间的那些线呢？

添加到@kennyzx 的回复。您所说的线条实际上是Reveal Highlight。您可以在\(Program Files)\Windows Kits\10\DesignTime\CommonConfiguration\Neutral\UAP\your sdk version\Generic\generic.xaml.

                            </VisualState>
                        </VisualStateGroup>

                    </VisualStateManager.VisualStateGroups>
                </ListViewItemPresenter>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

您可以看到它使用了许多“显示”主题资源。所有这些资源名称都包含“显示”一词。例如，RevealBackground="{ThemeResource ListViewItemRevealBackground}"。

如果你不想要它，你可以把它们都换掉。
