Question

嗨我有疑问，如果内容大小小于ListView区域，是否有可能使listview更小，但如果内容更大，请将ListView保留为原样？

目前我有：

<Grid Margin="0,5,0,0">

    <Grid.RowDefinitions>
        <RowDefinition Height="Auto"></RowDefinition>
    </Grid.RowDefinitions>

    <ListView Grid.Row="0" x:Name="Zones" Width="400" Margin="0,0,0,57" MaxHeight="240" Height="Auto" VerticalAlignment="Top">            
        <ListView.ItemContainerStyle>
            <Style TargetType="ListViewItem">
                <Setter Property="HorizontalContentAlignment" Value="Stretch"/>
                <Setter Property="VerticalContentAlignment" Value="Top"/>
                <Setter Property="HorizontalAlignment" Value="Stretch"/>
                <Setter Property="VerticalAlignment" Value="Top"/>
            </Style>
        </ListView.ItemContainerStyle>

        <ListView.ItemTemplate>
            <DataTemplate>
                <StackPanel Tag="{Binding number}" Background="#FF0E1D23" Margin="0,5,0,0" VerticalAlignment="Top" Height="114" Tapped="Zone_Tapped">
                    <Grid>
                        <Grid Visibility="{Binding IsVisible}" Height="115" HorizontalAlignment="Left" Width="13" Background="#FFA4EB1B" VerticalAlignment="Top"/>
                        <TextBlock TextWrapping="Wrap" Text="{Binding name}" Margin="48,10,10,63" FontSize="24"/>
                        <Image Margin="48,64,310,18" Source="{Binding modeImg}"/>
                        <Image Margin="117,64,241,18" Source="{Binding fireImg}"/>
                        <Image Margin="194,64,164,18" Source="{Binding breakinImg}"/>
                        <Image Margin="271,64,87,18" Source="{Binding awareImg}"/>
                        <Image Margin="348,64,10,18" Source="{Binding sabotageImg}"/>
                    </Grid>
                </StackPanel>
            </DataTemplate>
        </ListView.ItemTemplate>
    </ListView>

    <StackPanel Grid.Row="1" x:Name="ZoneMenu1" Background="#FF0E1D23" Margin="0,5,0,0"  Height="85" Visibility="Collapsed" VerticalAlignment="Top">
        <Grid Height="87">
            <Image x:Name="Action1" Margin="10,10,320,0" RenderTransformOrigin="0.5,0.5" HorizontalAlignment="Center" VerticalAlignment="Top" Source="ms-appx:///Assets/Images/TopNav/_troubles_48.png" Height="67" Width="70"></Image>
            <Image x:Name="Action2" Margin="106,10,225,0" RenderTransformOrigin="0.5,0.5" HorizontalAlignment="Center" VerticalAlignment="Top" Source="ms-appx:///Assets/Images/TopNav/_troubles_48.png" Height="67" Width="69"></Image>
            <Image x:Name="Action3" Margin="210,10,123,0" RenderTransformOrigin="0.5,0.5" HorizontalAlignment="Center" VerticalAlignment="Top" Source="ms-appx:///Assets/Images/TopNav/_troubles_48.png" Height="67" Width="67"></Image>
        </Grid>
    </StackPanel>
</Grid>

删除ListView的底部边距57 - 将其设为0。

你的代码中发生的是底部的57个边距强制ListView的底部总是距离屏幕底部57个像素，即使没有足够的内容可以拉伸那么远。

现在因为高度设置为拉伸且对齐为“顶部”，如果在没有设置边距时内容不需要屏幕的整个高度，则ListView将缩小（边距为0,0,0,0意味着没有使用保证金，而不是0像素的边际......这很奇怪，但就是这样。）
