错误膨胀 class androidx.core.widget.NestedScrollView
Error inflating class androidx.core.widget.NestedScrollView
我正在使用 NestedScrollView，但出现错误 Error inflating class androidx.core.widget.NestedScrollView.I also tried android.support.v4.widget.NestedScrollView。但是两者都不起作用并且出现错误。在嵌套滚动视图中有线性布局，在线性布局中，有一个图像视图、一个文本视图和回收视图。我必须添加任何依赖项才能用于 NestedScrollView 吗？请帮助解决这个问题。提前谢谢你。

从 NestedScrollView 中删除 android:nestedScrollingEnabled="false" 并将其添加到 RecyclerView，它应该可以正常工作。
