Question

在我的应用资料页面中，我水平显示了一些按钮，它在iPhone 7中看起来不错，但是当涉及到iPhone 5时，由于屏幕尺寸较小，按钮看起来不太好。我想让按钮的布局在小屏幕上垂直对齐。请参阅以下示例代码。

`

constructor(router:Router) {
  router.events.forEach((event) => {
    if(event instanceof NavigationStart) {
    }
    // NavigationEnd
    // NavigationCancel
    // NavigationError
    // RoutesRecognized
  });
}

`

这两个文本在所有屏幕中水平对齐。如何让它在小屏幕上自动垂直对齐？

正如我们发现的那样，您的问题实际上是关于更改StackPanel 的堆叠方向，而不是关于对齐。

要实现这一目标，您需要使用WhileWindowSize和WhileWindowPortrait / WhileWindowLandscape等触发器。在Responsive layout docs中已经很好地解释了这一点。

这是一个示例应用程序，可以满足您的需求：

<App>
    <Text ux:Class="TitleText" Color="#000" TextAlignment="Center" Padding="2"/>
    <!-- create a new trigger shorthand for when we are running on a "big screen" -->
    <WhileWindowSize ux:Class="WhileBigScreen" GreaterThan="599,1" />

    <!-- by default (on small screens in portrait), stack things vertically -->
    <StackPanel ux:Name="textPanel" Alignment="Center">
        <TitleText ux:Name="topText">This is a long text aligned horizontally</TitleText>
        <TitleText ux:Name="bottomText">This is a another long text</TitleText>
    </StackPanel>

    <!-- when running on a big screen, stack things horizontally disregarding what the device orientation is -->
    <WhileBigScreen>
        <Change textPanel.Orientation="Horizontal" />
    </WhileBigScreen>
    <!-- when running on a small screen, only stack things horizontally when in landscape -->
    <WhileBigScreen Invert="true">
        <WhileWindowLandscape>
            <Change textPanel.Orientation="Horizontal" />
        </WhileWindowLandscape>
    </WhileBigScreen>
</App>

如何在小屏幕上使水平对齐元素垂直？
