How to add RecyclerView in xml in android Lollipop

I have updated my android SDK with Android 5.0 (API 21); I have also updated Platform tools and Build tools.

I am getting The following classes could not be found: - android.support.v7.widget.RecyclerView (Fix Build Path, Edit XML, Create Class) error after adding RecycleView in layout xml file.

My layout xml file looks like follows:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.example.androidlintro.MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

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

</RelativeLayout>

can anyone tell me what's going wrong. Why I am getting this error, even after downloading complete set of software (new SDK, build tools, platform tools etc)

Note: I am using eclipse IDE

For Android Studio:

  1. Select: File -> Project Structure... -> Dependencies

  2. Click the "+" in the upper right corner and choose "1 Library dependency"

  3. Search for "com.android.support:recyclerview"

  4. You will see the current version of the library. Slect it and click "OK"

  5. Gradle will sync and you are ready.

ECLIPSE

If your problem is not solved or for future readers , here is the answer: From android sdk manager download Android Support Library first.

Go to this location and copy .aar file from here

X:\android-sdk\extras\android\m2repository\com\android\support\recyclerview-v7\21.0.0

Then rename it as .zip file then unZIP it then find classes.jar file , rename it with some proper name like 'RecyclerView_v7.jar' Then copy the that .jar file in you project library. Add it to build path then restart eclipse so that it can be instantiated (not necessary but i had to do this).

Make sure the Android Support Library is included in your project.

In Eclipse: Right click on Project -> Properties -> Android

Then add the Android Support Library to the build path.

Then clean the project and build.
