英文:
OnBackButtonPressed-Event not reached
问题
在我的.NET MAUI应用程序中，我通过以下方式导航到我的ContentPages之一：
await Shell.Current.GoToAsync(nameof(ManagePeopleItem), true);
该页面在AppShell.xaml.cs中注册：
Routing.RegisterRoute(nameof(ManagePeopleItem), typeof(ManagePeopleItem));
所以，当我显示这个页面时，我可以看到导航栏中的返回按钮"<-"。但当我单击此按钮并重写"OnBackButtonPressed()"时，此代码从未被触发。我还尝试在AppShell.xaml.cs中重写它，但在那里也没有触发。
我做错了什么？
英文:
In my .NET MAUI App, I navigate to one of my ContentPages via:
await Shell.Current.GoToAsync(nameof(ManagePeopleItem), true);
The page is registered in AppShell.xaml.cs via:
Routing.RegisterRoute(nameof(ManagePeopleItem), typeof(ManagePeopleItem));
So, when I display this Page, I can see the Back Button "<-" in my Navigation Bar. But when I click this Button and override "OnBackButtonPressed()" this Code is never reached. I also tried to override it in AppShell.xaml.cs, but it is also not fired there.
What am I doing wrong?

我测试了你提供的代码。结果显示发生了与你相同的情况。
我搜索了相关的案例。最终我找到了这个：On Screen Back Button Does Not Fire OnBackButtonPressed in Android 在 GitHub 上。当你在 Windows 上运行而不是 Android 时，OnBackButtonPressed 事件可以被触发。但对于 Android，它无法。你可以关注这个问题。
英文:
I tested the code you provided. And it shows the same situation happened to you.
I searched relevant cases about it. Finally I found this: On Screen Back Button Does Not Fire OnBackButtonPressed in Android on GitHub. When you run it on Windows instead of Android, OnBackButtonPressed-Event can be reached. But for Android, it can't. You can follow up this issue.
