标签： xml android-studio android-layout android-recyclerview androidx

我刚刚通过Android Studio菜单选项Refactor-> Refactor to AndroidX迁移到androidx

我遇到以下错误：

android.view.InflateException：二进制XML文件第2行：膨胀类androidx.recyclerview.widget.RecyclerView时出错

有什么主意吗？

我已经尝试过此问题的答案，但他们没有帮助我

Error inflating class androidx.constraintlayout.ConstraintLayout after migration to androidx

2 个答案:

答案 0 :(得分：0)

我将XML中的签名更改为androidx.recyclerview.widget.RecyclerView并有效。

答案 1 :(得分：0)

首先在 XML 文件中确保你有这个签名

androidx.recyclerview.widget.RecyclerView

如果你有的话

打开logcat 并阅读整个错误。您可能会看到由 .. 引起的，这是您的实际错误 对我来说是@dimen/somedimen。我写的值是 10，所以当我修复它时是 10dp。我的问题解决了。
