How to use androidx.recyclerview.widget.RecyclerView with tools:listitem?

How to use androidx.recyclerview.widget.RecyclerView with tools:listitem?
I have this layout:

<?xml version="1.0" encoding="utf-8"?>

<androidx.recyclerview.widget.RecyclerView

    xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools"

    android:id="@+id/recyclerViewActors"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"

    tools:layoutManager="androidx.recyclerview.widget.GridLayoutManager"

    tools:listitem="@layout/list_item_actor"

    tools:itemCount="5"

    tools:orientation="horizontal"

    tools:scrollbars="horizontal"

    tools:spanCount="2"/>

but Design tab doesn't show preview:

And if I change androidx.recyclerview.widget.RecyclerView in this layout to ListView, the preview works:

I see in the display of android studio this java.lang.ClassNotFoundException: androidx.recyclerview.widget.GridLayoutManager can explain why you can't have the display. So he can't display because he not find this

Do you use implementation 'androidx.recyclerview:recyclerview:1.0.0-beta01' or implementation 'androidx.recyclerview:recyclerview:1.0.0-alpha1' because when I use alpha I can see but when I change I don't see preview

From your code it seems that your recyclerview is the root element of the XML, and is missing the reference from xmlns:tools

Try to use another root element, as a constraint layout or even just layout as per example of google sunflowerapp:

<layout xmlns:android="http://schemas.android.com/apk/res/android"

    xmlns:app="http://schemas.android.com/apk/res-auto"

    xmlns:tools="http://schemas.android.com/tools">



    <androidx.recyclerview.widget.RecyclerView

            android:id="@+id/plant_list"

            android:layout_width="match_parent"

            android:layout_height="match_parent"

            android:clipToPadding="false"

            android:paddingLeft="@dimen/margin_normal"

            android:paddingRight="@dimen/margin_normal"

            app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"

            tools:context="com.google.samples.apps.sunflower.GardenActivity"

            tools:listitem="@layout/list_item_plant" />



</layout>
