我正在构建一个显示天气数据的UWP应用程序。目前我正在处理一个在枢轴
中使用的dataTemplate
我无法获得相对于屏幕尺寸(或其父容器)的Stackpanels宽度,并且无法将它们居中,我还希望相对于屏幕尺寸设置每边的边距(因为我,我用html之前放心。)
也可以将图像作为每个堆栈面板的背景,或者在我获取Error: "The property 'VisualTree' is set more than once"
时将数据显示在数据旁边?
我已检查过此处可用的所有其他帖子但尚无法找到解决方案

你只需要使用StackPanel
进行布局就太过分了。如果你想做一些相对大小调整,你需要使用转换器和一些使用帮助器的绑定,比如UWP社区工具包中的FrameworkExtensions。
或者你可以使用网格来利用它们的列大小:
<Pivot>
<PivotItem Header="Thursday">
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="8*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid BorderBrush="Black" BorderThickness="2" Margin="2" HorizontalAlignment="Stretch" Background="DeepSkyBlue" Grid.Column="1">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="Auto"/>
</Grid.ColumnDefinitions>
<Image Source="http://unsplash.it/g/100/150" Stretch="Fill" Height="100" Width="150" Margin="20" Grid.Column="1"/>
<StackPanel VerticalAlignment="Center">
<StackPanel Orientation="Horizontal" >
<TextBlock HorizontalAlignment="Stretch" FontWeight="Bold" Text="Temperature: " ></TextBlock>
<TextBlock HorizontalAlignment="Stretch" Text="{Binding temp}"></TextBlock>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Time : " FontWeight="Bold"></TextBlock>
<TextBlock Text="{Binding dtime}"></TextBlock>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Description : " FontWeight="Bold"></TextBlock>
<TextBlock Text="{Binding desc}"></TextBlock>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Humidity : " FontWeight="Bold"></TextBlock>
<TextBlock Text="{Binding humidity}"></TextBlock>
</StackPanel>
<StackPanel Orientation="Horizontal">
<TextBlock Text="Windspeed : " FontWeight="Bold"></TextBlock>
<TextBlock Text="{Binding windSpeed}"></TextBlock>
</StackPanel>
</StackPanel>
</Grid>
</Grid>
</PivotItem>
</Pivot>
上面的例子也将图像放在一边,中间区域占据了枢轴宽度的80%。
如果没有关于您已设置的列表/数据透视组合的更多信息,有助于提供更多帮助。
