Question

如何在Windows UWP中为分段控制制作自定义渲染器。我按照这个link来自定义渲染IOS和android中的分段控件。但我找不到任何关于Windows UWP的东西。任何人都可以在此提供任何资源，或者是否有任何替代方法来执行此操作类似于Windows UWP中的分段控制。

Answer 1

我自己找到了解决方案。

我最近发现了一个nuget包FreshEssentials。它具有分段按钮组的实现。按照此github link查找实施。它易于使用。

Answer 2

现在有一个Xamarin Forms跨平台库可以做到这一点。

Plugin Segmented Control for .NET Standard

Answer 3

我用自定义样式的RadioButton做了一次。编辑按钮的RadioButton样式 - 创建按需查看的已选中和未选中样式，并为它们指定相同的组，以便您当时只能选择一个按钮。不知道是否有更简单的方法。
