如何在listview中拉伸listviewitem

Question

开发人员.

我尝试在水平方向上拉伸listview项目.我重置了ItemContainerStyle,而horizentalalignment是strech.这是MainPage.xaml中的所有代码.

<Grid x:Name="rootGrid"
      HorizontalAlignment="Stretch"
      MinWidth="320"
      MaxWidth="480"
      Width="Auto">
    <ListView x:Name="infoFlowListView" 
              MinWidth="320"
              MaxWidth="480"
              Width="Auto"
              HorizontalAlignment="Stretch">
        <ListView.ItemTemplate>
            <DataTemplate>
                <local:MyUserControl1 MinWidth="300" HorizontalAlignment="Stretch"></local:MyUserControl1>
            </DataTemplate>
        </ListView.ItemTemplate>
        <ListView.ItemContainerStyle>
            <Style TargetType="ListViewItem">
                <Setter Property="HorizontalAlignment" Value="Stretch"></Setter>
            </Style>
        </ListView.ItemContainerStyle>
    </ListView>
</Grid>

这是MainPage.xaml.cs中的所有代码

public MainPage()
    {
        var items = new List<MyUserControl1>();
        for (int i = 0; i < 50; i++)
        {
            items.Add(new MyUserControl1());
        }
        this.InitializeComponent();
        infoFlowListView.ItemsSource = items;
    }

这是MyUserControl.xaml中的所有代码

<Grid>    
<Grid.ColumnDefinitions>
    <ColumnDefinition Width="*"></ColumnDefinition>
    <ColumnDefinition Width="4*"></ColumnDefinition>
</Grid.ColumnDefinitions>

         VerticalAlignment="Center" 
         HorizontalAlignment="Center" 
         Stretch="Uniform">
    <Ellipse.Fill>
        <ImageBrush ImageSource="Assets/1.png"></ImageBrush>
    </Ellipse.Fill>
</Ellipse>

<RelativePanel x:Name="topRelativePanel"
               Grid.Column="1" Grid.Row="0"
               HorizontalAlignment="Stretch">
    <TextBlock Text="TestName"
               VerticalAlignment="Bottom"
               RelativePanel.AlignLeftWithPanel="True"
               FontSize="12"
               HorizontalAlignment="Stretch"></TextBlock>
    <TextBlock Text="Author"
               VerticalAlignment="Bottom"
               RelativePanel.AlignRightWithPanel="True"
               FontSize="12"
               HorizontalAlignment="Stretch"
               Margin="0,0,8,0"></TextBlock>
</RelativePanel>

<TextBlock x:Name="nameTextBlock"
           Grid.Column="1" Grid.Row="1"
           Text="Name" 
           TextTrimming="WordEllipsis"
           VerticalAlignment="Stretch"
           HorizontalAlignment="Stretch"
           FontSize="18" >
</TextBlock>

<Grid x:Name="bottomGrid"
      Grid.Column="1" Grid.Row="2"
      VerticalAlignment="Top"
      HorizontalAlignment="Stretch">
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"></ColumnDefinition>
        <ColumnDefinition Width="*"></ColumnDefinition>
        <ColumnDefinition Width="3*"></ColumnDefinition>
    </Grid.ColumnDefinitions>
    <TextBlock Grid.Column="0"
               HorizontalAlignment="Stretch"
               Text="90"></TextBlock>
    <TextBlock Grid.Column="1"
               HorizontalAlignment="Stretch"
               Text="48"></TextBlock>
    <TextBlock Grid.Column="2"
               HorizontalAlignment="Stretch"
               Text="20170330 08:33"
               Margin="0,0,0,0"></TextBlock>
</Grid>

<Border Background="LightGray"
        VerticalAlignment="Stretch"
        HorizontalAlignment="Stretch"
        Grid.Row="3" Grid.Column="0" Grid.ColumnSpan="2"></Border>

我在6inch模拟器上测试这些代码,并添加了此示例的屏幕截图.

移动仿真器的结果并不相同.这是不同的模拟器截图. 4英寸 屏幕截图示例 这些屏幕截图的右侧是不同的.

我尝试在水平方向上拉伸listview项目.

你需要设置HorizontalContentAlignment属性,而ListViewItem不是HorizontalAlignment.使用以下代码,内容ListViewItem将延伸.

<ListView.ItemContainerStyle>
    <Style TargetType="ListViewItem">
        <Setter Property="HorizontalContentAlignment"  Value="Stretch"></Setter>
    </Style>
</ListView.ItemContainerStyle>

默认ListViewItem 样式和模板不会打开HorizontalAlignmentsetter HorizontalContentAlignment.
