尝试在 .net MAUI 中迁移 SearchBar 自定义渲染器时出现 Android.Views.InflateException

Question

有人在下面的 git 链接中报告了我的确切问题和相同的代码。代码示例也存在于 GIT 报告的问题中。 将我的 Xamarin 应用程序迁移到 MAUI 以及使用自定义 SeachBar/SearchBarRenderer 时，应用程序崩溃并出现以下错误。

GIT 链接：https://github.com/dotnet/maui/issues/22522

有人有相同的解决方案或面临类似的问题并找到替代方案吗？

从.NET MAUI Shell搜索文档中我们可以发现SearchHandler被设计为添加在页面顶部。

SearchHandler 添加在 ContentPage 内部，如果将其放在其他位置，则不会显示。

我想要在多个页面中搜索处理程序，但搜索处理程序无法实现多个位置，并且无法实现除页面顶部之外的内部布局。
