Question

我想让两个单选按钮显示为切换按钮（因此用户只能选择一个，但它们看起来像按钮）。我看到了关于WPF的答案如何根据切换按钮为单选按钮创建样式，但在UWP中，这不受支持：

<RadioButton Style="{StaticResource {x:Type ToggleButton}}" />

实现这一目标的最简洁方法是什么？

Answer 1

使用XAML，这很容易做到。

这是我做的：

创建一个按钮并右键单击它，选择编辑模板，然后选择编辑复制。
创建单选按钮，右键单击它，选择编辑模板，然后编辑副本。
现在用按钮样式中的XAML替换单选按钮样式的样式。
仅保留单选按钮特定的视觉状态：已选中，未选中等。
现在确保动画引用正确的UIElements。你可以根据需要修改单选按钮的样子。

这将为您提供一个看起来像切换按钮的单选按钮。

这是它的样子：

这是单选按钮样式：

<Style TargetType="RadioButton">
        <Setter Property="Background" Value="{ThemeResource ButtonBackground}" />
        <Setter Property="Foreground" Value="{ThemeResource ButtonForeground}" />
        <Setter Property="BorderBrush" Value="{ThemeResource ButtonBorderBrush}" />
        <Setter Property="BorderThickness" Value="{ThemeResource ButtonBorderThemeThickness}" />
