Question

在迁移到AndroidX后，我遇到很多数据绑定错误（重构>迁移到AndroidX）。

error: cannot find symbol
      @Nullable ViewGroup root, boolean attachToRoot, @Nullable DataBindingComponent component) {
                                                                ^
  symbol:   class DataBindingComponent
  location: class ActivityInfoBinding

我正在使用Android Studio 3.2 Beta 2

我的依赖项：

Answer 1

更新到最新的Android Studio并重新导入该项目解决了我的问题。

Answer 2

要解决此问题，我必须更新布局文件上的所有类名。

发件人：

<android.support.design.widget.CoordinatorLayout
<android.support.v7.widget.RecyclerView
...

收件人：

<androidx.core.widget.NestedScrollView
<androidx.coordinatorlayout.widget.CoordinatorLayout
...

之后，数据绑定错误消失了。

我运行了迁移工具，但不幸的是，它没有在布局xml上固定类名！
