Didn't find class "android.support.v7.widget.RecyclerView

If you are updated your android studio to v-3.4.2

then Change from

android.support.v7.widget.RecyclerView

to

androidx.recyclerview.widget.RecyclerView

it's work for me.

In eclipse in your workspace, create a new project using the existing code, then select path to Recycler in android SDK support and in properties select compiler google API 20 or 21 and check Is Library.

After that, in the workspace select your own project, right-click properties and go to android section and in library click add button and select your Recycler project from list.

Next you must do clean all project from project menu .

Sorry if my english is so bad but its ur solution and just adding suuport v7 as jar through errors its not like v4.

Simple Two Steps:

In stand off

<android.support.v7.widget.RecyclerView
            android:id="@+id/rv_News"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scrollbars="vertical" />  

Replace with androidx package in xml file as below

<androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical" />
