使单选按钮显示为UWP中的切换按钮

Question

我想使两个单选按钮显示为切换按钮（因此用户只能选择一个，但看起来像按钮）。 只见回答关于WPF你如何才能创建一个单选按钮风格的基础上，切换按钮，但在UWP，这是不支持：

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

什么是实现这一目标的最彻底的方法？

Answer 1

使用XAML这很容易做到。

这里是我做过什么：

• 创建一个按钮，右键单击它，选择编辑模板，然后编辑复制。
• 创建一个单选按钮，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。
• 只保留单选按钮特定的视觉状态：选中，取消选中等。
• 现在确保动画引用正确的UIElements。您可以修改单选按钮的外观，但是您可以选择。

这会给你一个单选按钮，看起来像一个切换按钮。

这里是它的样子：

，这里是单选按钮样式：

     <Setter Property="Background" Value="{ThemeResource ButtonBackground}" /> 
     <Setter Property="Foreground" Value="{ThemeResource ButtonForeground}" />

希望这回答了你的问题。
