从Android Studio中的Refactor工具迁移到AndroidX后，出现此错误- android.view.InflateException：二进制XML文件第42行：错误膨胀类..

在我工作完美之前，但只有在迁移之后，它才会在某些活动中出现这些错误。

我面临着类似的事情，我的问题是，其中一个布局文件在迁移到AndroidX后仍在使用支持库。通过读取整个堆栈跟踪发现了这一点。

答案 1 :(得分：0)

问题看起来像这样。

a201,[XYZ1 - XYZXYZ, XYZXYZ]
f110,[XYZ1 - XYZXYZ, XYZXYZ]
a202,[XYZ2 - XYZXYZ, XYZXYZ]
f110,[XYZ2 - XYZXYZ, XYZXYZ]

顺便说一句，我假设您已经在build.gradle中定义了支持设计库

    app:errorTextAppearance="@style/error_appearance"
    app:hintTextAppearance="@style/TextAppearance.App.TextInputLayout

答案 2 :(得分：0)

我遇到了同样的问题，使我整整疯了一天。我发现res文件夹中的样式文档具有其他版本（v19和v23），尽管已在常规样式表中进行了修复，但它们的主题仍然具有appcompat。我刚刚删除了其他样式表，它就起作用了。
