Android Studio 3.5+ 使用androidx的recyclerView

File->project structure->Dependencies:

点击All Dependencies处的加号,选择Library Dependency:

在step1处输入recyclerView,点击search,搜索到以后,选中,点击ok即可

二 在layout中加入

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/RecyclerViewId"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
</LinearLayout>
