我有2个recycleView，但是用的同一个线性布局导致错误如下

LayoutManager androidx.recyclerview.widget.LinearLayoutManager@51ddcd is already attached to a RecyclerView: androidx.recyclerview.widget.RecyclerView{dfe1682 VFED..... ......I. 0,0-0,0 #7f0901dd app:id/notInstallRv}, adapter:com.appsinnova.android.keepshare.clean.cleantrash.adapter.UnInstalledAdapter@a976193, layout:androidx.recyclerview.widget.LinearLayoutManager@51ddcd, context:com.appsinnova.android.keepshare.clean.InstallPackageCleanActivity@62aecf7

2 解决办法

用两个不同的线性布局分别给2个不同的RecycleView就可以了
