Question

使用ListView时，如何使每个DataTemplate项的内容扩展为100％？

我在HorizontalContentAlignment="Stretch"和ListView HorizontalAlignment="Stretch"中尝试了DataTemplate，但似乎没有任何效果，内容仍然与左边对齐。

我有这样的事情：

<ListView x:Name="questionsView" Background="{StaticResource ApplicationPageBackgroundThemeBrush}" HorizontalContentAlignment="Stretch">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Border Background="BlueViolet" HorizontalAlignment="Stretch">
                <Grid HorizontalAlignment="Stretch">
                    <TextBlock Text="{Binding}" />
                    <TextBlock HorizontalAlignment="Right">16 minutes ago</TextBlock>
                </Grid>
            </Border>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

我想在ListView和ItemTemplate之间还有一层。

我明白了。使用ListView.ItemContainerStyle setter设置HorizontalContentAlignment就可以了。即：

<ListView x:Name="questionsView" Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
    <ListView.ItemTemplate>
        <DataTemplate>
            <Border Background="BlueViolet">
                <Grid HorizontalAlignment="Stretch" Margin="0">
                    <TextBlock Text="{Binding}" />
                    <TextBlock HorizontalAlignment="Right">16 minutes ago</TextBlock>
                </Grid>
            </Border>
        </DataTemplate>
    </ListView.ItemTemplate>
    <ListView.ItemContainerStyle>
        <Style TargetType="ListViewItem">
            <Setter Property="HorizontalContentAlignment" Value="Stretch" />
        </Style>
    </ListView.ItemContainerStyle>
</ListView>

Answer 2

将 HorizontalContentAlignment 的项容器属性设置为Stretch，试试这个

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

这里重要的是ScrollViewer.HorizontalScrollBarVisibility，TextWrapping和ItemContainerStyle与HorizontalContentAlignment。其余的都是绒毛。

<ListView VerticalAlignment="Stretch"
          ScrollViewer.VerticalScrollBarVisibility="Auto"
          ScrollViewer.HorizontalScrollBarVisibility="Disabled">

    <ListView.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Prop1}" TextWrapping="Wrap"/>
        </DataTemplate>
    </ListView.ItemTemplate>

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

</ListView>

ListView ItemTemplate 100％宽度
