Answer 1

首先你的XAML格式不正确，你已经开始两次Grid标签，但最后没有关闭它。

其次，您的视觉状态是在不同的组中定义的，而它们应该在一个组中，因为我们只有两种不同的状态。

请在下面找到更新后的XAML

<Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">


        <VisualStateManager.VisualStateGroups>

                        <AdaptiveTrigger MinWindowWidth="1" />

                    </VisualState.StateTriggers>

                    <VisualState.Setters>

                        <Setter Target="CityName.FontSize" Value="14 " />

                        <Setter Target="TitleItem.FontSize" Value="14" />

                        <Setter Target="CalButton.Width" Value="100" />

                    </VisualState.Setters>
