Error inflating class android.support.v7.widget.RecyclerView

Question

I'm trying to use RecyclerView in my existing project, builds without errors but getting no class found error for the RecyclerView while inflating. Cannot see what I'm doing wrong. Thanks for helping!

//activity_main.xml

        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>
</LinearLayout>

//MainActivity.onCreate
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        recyclerView = (RecyclerView) findViewById(R.id.recyclerView);
        ItemData itemsData[] = { new ItemData("Help",R.drawable.visa),

        // 2. set layoutManger
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        // 3. create an adapter
        MyAdapter mAdapter = new MyAdapter(itemsData);
        // 4. set adapter
        recyclerView.setAdapter(mAdapter);

Here is a RecylerView Demo [recyclerviewdemo GitHub](https://github.com/writtmeyer/recyclerviewdemo) can you run this properly? — PrivatMamtora, Aug 25 '14 at 01:34
I tried creating a new test project just for testing recyclerview and it works but unable to figure out why it does not work when including in an existing project. That's why I copied all the code from layout to the build.gradle — nomongo, Aug 25 '14 at 04:13
recyclerview is only available when targeting Android-L at the moment, unless you are using a workaround to make it work on older versions? — athor, Aug 25 '14 at 08:13

Or... in my case, I was including the androidx version of RecyclerView in my dependencies (build.gradle) but using the other in my XML... Doh.

Replaced

android.support.v7.widget.RecyclerView

with

androidx.recyclerview.widget.RecyclerView

and it worked! :)

In the xml declaration of the RecyclerView: Replace

<android.support.v7.widget.RecyclerView

with

<androidx.recyclerview.widget.RecyclerView

Hope this works ^_^

for the new API Version, on the build.gradle - project dependencies add :

implementation 'androidx.recyclerview:recyclerview:1.0.0'

and in the layout, you should replace :

android.support.v7.widget.RecyclerView

with

androidx.recyclerview.widget.RecyclerView

In your layout file:

Use:

androidx.recyclerview.widget.RecyclerView

Instead:

android.support.v7.widget.RecyclerView

It will work for you.

If you do not want to use Androidx then in your gradle.properties file and do this:

android.useAndroidX=false

android.enableJetifier=false

Make sure you have added proper dependencies for recyclerView. Then check whether you have dependecy for cardView.

If yes, then

remove card view dependency
sync project
then again add card view dependency
clean project
rebuild project

It worked for me

This helped me to locate the problem. When I removed card view dependency and went to add it back again, in card view xml there was some attribute with unsupported value, which was not reported in compilation time, so after changing its value, everything worked. – Markonioninioni Sep 14 '22 at 17:09

I figured it out. Removing the following configuration in build.gradle makes the recyclerview work. This leads me to another question: android studio: gradle dependency error

--

configurations {
    // to avoid double inclusion of support libraries
    all*.exclude group: 'com.android.support', module: 'support-v4'
}

After trying everything on internet i solved recyclerview inflating error by observing small mistake. First, Did you check your android-support-v7-recyclerview.jar library present in libs folder? if it is then check if your manifest file that has target sdk version to 21

<uses-sdk
        android:minSdkVersion="11" //or whatever you need
        android:targetSdkVersion="21" />

may be this can help for someone in future and not wasting days behind it as i did.

Check out my answer here Error inflating class RecyclerView. In short, you need to import recyclerview and appcompat dependencies and sync before you are trying to add RecyclerView to your XML.

--- Quoted from Android website.

Dependencies

To use these features in versions of Android earlier than 5.0 (API level 21), include the Android v7 Support Library in your project as a Gradle dependency:

dependencies {
    compile 'com.android.support:appcompat-v7:21.0.+'
    compile 'com.android.support:cardview-v7:21.0.+'
    compile 'com.android.support:recyclerview-v7:21.0.+'

I had a similar same error message, and tried many of the suggested steps from the answers on this site.

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.abc.def/com.abc.def.MainActivity}: android.view.InflateException: Binary XML file line #8:

Finally realized that for some reasons the tag in my layout was:

android.support.v7.internal.widget.RecyclerView

instead of

android.support.v7.widget.RecyclerView.

I am not sure how 'internal' crept in between v7 and widget, but once I removed that, the error went away. Not saying other people will make the same mistake, but just to let people know that a typo somewhere in your layout xml could be the cause of this error message.

Check your layout.xml file...Cant stop my laughing... I made a stupid mistake...

I put

<android.support.v7.wodget.RecyclerView

instead of

<android.support.v7.widget.RecyclerView

look at the small 'o', it wasted me 30 mins or more to check other files... [looking forward my answer can save your time]

Add below line in Gradle file:

dependencies {
    //recyclerview
    implementation 'androidx.recyclerview:recyclerview:1.0.0'
}

Add below code in your activity layout.xml:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">

<androidx.recyclerview.widget.RecyclerView
    android:id="@+id/recyclerview"
    android:layout_width="0dp"
    android:layout_height="0dp"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

Your Android studio auto imports the androidx recyclerview.

AndroidX is a major improvement to the original Android Support Library. Like the Support Library, AndroidX ships separately from the Android OS and provides backwards-compatibility across Android releases.

Here is the reference AndroidX: https://developer.android.com/jetpack/androidx

I too got same exception.

simple solution is add layout_behaviour to recycler view:
