Is there a way to show a preview of a RecyclerView's contents as Grid in the Android Studio editor?

When I add the RecyclerView to the layout, it shows up as a list view in vertical order. I am using tools:listitem for this. Is there a way, such that it displays as grid but not as list in the Android Studio Editor?

If you want to see the effect only in the preview without change the app behavior you can use the "tools" namespace as you did with listitem:

<android.support.v7.widget.RecyclerView
        android:id="@+id/rcv_collection"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:layoutManager="android.support.v7.widget.GridLayoutManager"
        tools:spanCount="2"
        tools:listitem="@layout/item_collection"/>

This Worked for me (AndroidX): For 3 column grid

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/rvServiceList"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layoutManager="androidx.recyclerview.widget.GridLayoutManager"
    app:spanCount="3"
    tools:itemCount="20"
    tools:listitem="@layout/row_item_service" />

To show list horizontally in preview, just use these two attributes

tools:orientation="horizontal"
tools:layoutManager="android.support.v7.widget.LinearLayoutManager"

here's the final code

<android.support.v7.widget.RecyclerView
        ...
        tools:listitem="@layout/single_item_layout"
        tools:orientation="horizontal"
        tools:layoutManager="android.support.v7.widget.LinearLayoutManager"/>
