MAUI Error inflating category com.google.androidmaterial.appbar.App BarLayout
原标题：MAUI Error inflating class com.google.android.material.appbar.AppBarLayout

我已根据文件样本“Xaminals”撰写了一份MAUI数据。 它汇编了罚款,但在安乐器的初始化时,我有以下例外:

Android.Views.InflateException

Message.companyname.shvn_guide:layout/flyoutcontent: Binary XML file Line #1 in com.companyname.shvn_guide:layout/flyoutcontent: Error inflating category com.google.androidmaterial.appbar.AppBarLayout

Environment

Windows 10 Pro 19045.3324 16 GB RAM Visual Studio Community Ed. 17.7.3 .NET 7.0 Emulator Pixel 5 API - 33 (Android 13 - API 33)

The error message and stack trace above is all info I get from Visual Studio. I have found no relevant info on Internet. A similar app written for Xamarin did NOT cast this exception. I would appreciate any info on this problem.

我已根据文件样本“Xaminals”撰写了一份MAUI数据。 为Xamarin撰写的类似材料中,NOT表示这一例外。

You mean that you made a MAUI app with reference to this: Xaminals (xamarin-forms-samples)? If so, You need to notice that Xamarin s project is a bit different from MAUI s. For more info about it, you can refer to the official doc: Migrate from Xamarin.

You can directly use this code sample:Xaminals (maui-samples). I tested it, and it works well.
