我发现了这个问题，这是一个错误，我向 Google ( b.android.com ) &他们回答了

是的，我们知道这个问题，它将在下一个 alpha 版本中修复.这是:问题链接

Yep, we are aware of this issue, it will be fixed in the next alpha release. this is the : issue link

.

那么如何解决:我在 build.gradle (Module) 中更新到 alpha3 版本的库时遇到了这个问题:

So how to solve it: I faced the problem when updated to alpha3 version of library in build.gradle (Module) :

  implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha3' 

只需将其降级到较低版本即可:

Just downgrade it to lower version:

  implementation 'androidx.constraintlayout:constraintlayout:2.0.0-alpha2' 

现在好了.

问题是constraintlayout:2.0.0-alpha3库和attrs.xml在编译时合并的冲突！

The problem was the conflict between constraintlayout:2.0.0-alpha3 library and attrs.xml merging on compile time!

而对您而言，这可能只是其他一些库之间的冲突(只需检查上次更新的库)

and for you it might be just conflicts between some other libraries ( just check last updated libraries )
