GridView ItemTemplate 全宽

Question

我的问题是：如何将 DataTemplate 拉伸到屏幕的整个宽度。我尝试了很多解决方案，但它们不起作用。我尝试了 HorizontalContentAlignment、设置 GridView.ItemContainerStyle 等。但没有任何效果。谁能解释我该怎么做？

这是我的部分代码：

<Grid Style="{StaticResource GeneralAppBackground}">
    <Grid.RowDefinitions>
        <RowDefinition Height="Auto" />
        <RowDefinition Height="*" />
    </Grid.RowDefinitions>
    <Pivot x:Name="AccountInfoOptions" Grid.Row="1">
        <PivotItem Header="История">
            <GridView ItemsSource="{x:Bind CheckoutList}" Margin="5,0,5,0">
                <GridView.ItemTemplate>
                    <DataTemplate x:DataType="data:UserCheckout">
                        <StackPanel Orientation="Horizontal" BorderBrush="Transparent" Background="White" Padding="5" Margin="0,5,0,0">
                            <StackPanel Grid.Column="0" Orientation="Vertical" VerticalAlignment="Center" Margin="0,0,10,0">
                                <TextBlock FontSize="14" Text="{x:Bind CheckoutDate}" Foreground="#979797" />
                                <TextBlock FontSize="14" Text="{x:Bind CheckoutTime}" Foreground="#979797" />
                            </StackPanel>
                            <StackPanel Grid.Column="1" VerticalAlignment="Center">
                                <StackPanel Orientation="Horizontal">
                                    <TextBlock Text="{x:Bind CheckoutSum}" FontSize="22" FontWeight="Bold" />
                                    <Image Source="/Assets/TengeIcon.png" Width="20" Margin="5,0,0,0"/>
                                </StackPanel>
                                <TextBlock Text="{x:Bind CheckoutTitle}" TextAlignment="Center" />
                            </StackPanel>
                        </StackPanel>
                    </DataTemplate>
                </GridView.ItemTemplate>

                <GridView.ItemContainerStyle>
                    <Style TargetType="GridViewItem">
                        <Setter Property="HorizontalContentAlignment" Value="Stretch" />
                    </Style>
                </GridView.ItemContainerStyle>
            </GridView>
        </PivotItem>
   </Pivot>

让它发挥作用的关键是改变 ItemsPanelTemplate。定义为页面资源：

<Page.Resources>
    <ItemsPanelTemplate x:Key="ItemsPanelTemplate">
        <ItemsStackPanel />
    </ItemsPanelTemplate>
</Page.Resources>

现在将其设置为 ItemsPanel 用于您的 GridView:

<GridView ItemsSource="{x:Bind CheckoutList}" 
          Margin="5,0,5,0" 
          ItemsPanel="{StaticResource ResourceKey=ItemsPanelTemplate}">

这将允许单个项目伸展到整个宽度。您仍然需要将 DataTemplate 中的根 StackPanel 替换为 Nikita 建议的 Grid：

<DataTemplate x:DataType="local:UserCheckout">
    <Grid BorderBrush="Transparent" Background="White" Padding="5" Margin="0,5,0,0">
        <Grid.ColumnDefinitions>
            <ColumnDefinition />
            <ColumnDefinition/>
        </Grid.ColumnDefinitions>
        <StackPanel Grid.Column="0" Orientation="Vertical" VerticalAlignment="Center" Margin="0,0,10,0">
            <TextBlock FontSize="14" Text="{x:Bind CheckoutDate}" Foreground="#979797" />
            <TextBlock FontSize="14" Text="{x:Bind CheckoutTime}" Foreground="#979797" />
        </StackPanel>
        <StackPanel Grid.Column="1" VerticalAlignment="Center">
            <StackPanel Orientation="Horizontal">
                <TextBlock Text="{x:Bind CheckoutSum}" FontSize="22" FontWeight="Bold" />
                <Image Source="/Assets/TengeIcon.png" Width="20" Margin="5,0,0,0"/>
            </StackPanel>
            <TextBlock Text="{x:Bind CheckoutTitle}" TextAlignment="Center" />
        </StackPanel>
    </Grid>
</DataTemplate>

您已经为内部 StackPanel 正确设置了 Grid.Column 属性。看来您之前曾尝试在那里使用 Grid。
