有没有办法对齐152and bar？同样与.. 15 MinutesRemaining和x？

这是我当前的代码：

 <Grid>
      <Frame Style="{StaticResource FrameStyle}">
            <Grid Style="{StaticResource TellyGridStyle}">
                <Frame Grid.Column="0" BackgroundColor="Green" Margin="0,10,10,10" Padding="20">
                    <Label Text="1" Style="{StaticResource TeamLabelStyle}" />
                </Frame>
                <Grid Grid.Column="1" Style="{StaticResource AutoGridStyle}">
                    <Grid Grid.Column="0" Grid.Row="0" Style="{StaticResource EvacuationGridStyle}">
                        <Label TextColor="Green" Text="152" FontSize="72" VerticalTextAlignment="End"  />
                        <Label Grid.Column="1" VerticalTextAlignment="End" Text="bar" TextColor="Blue" FontSize="54" />
                    </Grid>

为了避免由于使用不同大小的字体而导致每个标签垂直（Y/高度）大小不同的问题，并避免对这些标签的高度进行硬编码，您可以使用FormattedString.

这样，您就有一个标签，其高度是由最高元素（即字体）计算的，因此在使用YAlign="End" VerticalTextAlignment="End"您的文本时是底部对齐的。

<Grid Grid.Column="0" Grid.Row="0" Style="{StaticResource EvacuationGridStyle}">
    <Label YAlign="End" VerticalTextAlignment="End">
         <Label.FormattedText>
            <FormattedString>
              <Span Text="152" TextColor="Green" FontSize="72" />
              <Span Text="bar" TextColor="Blue"  FontSize="54" />
            </FormattedString>
          </Label.FormattedText>
   </Label>                            
</Grid>

注意：如果您需要更改 的离散元素，FormattedString就好像它们是单独的标签一样，您可以分配x:Name, BindingContext，Binding因为 aSpan是可绑定对象。

<Span x:Name="barValue" BindingContext="aContext" Text="{Binding BarValue}" TextColor="Green" FontSize="72" />
