ListView填充父窗口，屏幕等的宽度

Question

我试图显示一些数据从一个可观察集合到ListView。绑定工作正常。我唯一不能解决的问题是ListView的布局。我使用一个2行的网格来分割我的视图。ListView在第二行。我只尝试使用*来设置大多数来源中建议的列和行。ListView的代码如下:

<Grid Grid.Row="1" Margin="10,0,10,0" HorizontalAlignment="Stretch">
    <ListView ItemsSource="{Binding Collection}" HorizontalAlignment="Stretch">
        <ListView.ItemTemplate>
            <DataTemplate>
                <Grid HorizontalAlignment="Stretch">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    <TextBlock Grid.Column="0" HorizontalAlignment="Center" Text="{Binding Period}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="1" HorizontalAlignment="Center" Text="{Binding Currency}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="2" HorizontalAlignment="Center" Text="{Binding Date}" Foreground="{StaticResource ColorBrush}" FontSize="20" FontFamily="{StaticResource Family}"/>
                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</Grid>

当我对包含ListView和ListView本身的网格使用HorizontalAlignment="Stretch"时，数据显示在左侧，而没有获得父视图的整个宽度。当我显式地将Width设置为某个值(例如380)时，它显示OK。

<Grid Grid.Row="1" Margin="10,0,10,0">
    <ListView ItemsSource="{Binding Collection}" Width="380">
        <ListView.ItemTemplate>
            <DataTemplate>
                <Grid Width="380">
                    <Grid.ColumnDefinitions>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                        <ColumnDefinition Width="*"/>
                    </Grid.ColumnDefinitions>
                    <TextBlock Grid.Column="0" HorizontalAlignment="Center" Text="{Binding Period}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="1" HorizontalAlignment="Center" Text="{Binding ValueInCurrency}" Foreground="{StaticResource ColorBrush}" FontFamily="{StaticResource Family}" FontSize="20"/>
                    <TextBlock Grid.Column="2" HorizontalAlignment="Center" Text="{Binding Date}" Foreground="{StaticResource ColorBrush}" FontSize="20" FontFamily="{StaticResource Family}"/>
                </Grid>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>
</Grid>

但是我想知道一个更好的方法不使用隐式值，而是使用*.

试试这个。在</ListView.ItemTemplate>

之后添加以下内容

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