xaml - ListView ItemTemplate 100% 宽度

Question

如何制作每个ListView的内容使用 DataTemplate 时，项目扩展到 100% 宽度?

我试过 HorizontalContentAlignment="Stretch"在 ListView和 HorizontalAlignment="Stretch"在 DataTemplate ，但似乎没有任何效果，内容仍然向左对齐。

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 之间还有一层和 ItemTemplate .

我知道了。设置 ListView.ItemContainerStyle与 HorizontalContentAlignment二传手使伎俩。 IE。:

<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>
