Youtube player in RecyclerView in Android

In this post, I will learn about playing YoutubePlayerView in ReyclerView Android. We implement Youtube Player in RecyclerView using WebView with the help of an external library.

Introduction

As usually youtube player API works well in Android in full-screen view. If you want to play a youtube video inside subview, it’s thrown illegal overlay exception for the reason that youtube API is not allowed any kind of overlay, padding, and margin inside the View. Same if you want to play a video in RecylerView similarly Twitter Player Card. In Twitter, Player Card video is played as WebView with some metadata. You no need to learn deep. We have on prebuilt lib for this.

If you facing illegal overlay issue in youtube player, You are in right place. Basically,
YouTube Android Player API is strictly prohibited overlay, So while you play in RecyclerView in then the video will be stopped after few second. Now I explain hows play YoutubePlayer in RecyclerView like Twitter. I’m using a library Android YouTube Player.

This is the fully open source library. The player is run on Webview within IFrame API, is easy to maintain and scalable. This library uses YouTube’s own web player to play videos, to interact with YouTube the library uses the IFrame Player API, inside of a WebView, therefore the YouTube app is not required on the user’s device and there are no issues with YouTube Terms of Service. Let’s learn the implementation step by step

YoutubePlayerView in ReyclerView Sample App

Implementation Steps

1. First of all, create a new project with the name Youtube Player Example.

Go to file menu => Create a new project => Enter a project name and packages name => Select template => Finish

2. Add dependency inside app/build.gradle

Now we need to add below dependency in build.gradle

• AndroidX – Support lib
• Glide – For image loading lib
• ButterKnife – DI View Binding
• IFrame Player API – Youtube lib

2.1 Define youtube player and butterknife dependency

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    // replace support with androidx
    implementation 'androidx.appcompat:appcompat:1.0.2'
    implementation 'com.google.android.material:material:1.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'

    // Image loading lib
    implementation 'com.github.bumptech.glide:glide:4.9.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.9.0'
    // Youtube lib
    implementation 'com.github.PierfrancescoSoffritti:AndroidYouTubePlayer:7.0.1'
    // bind view
    implementation 'com.jakewharton:butterknife:10.1.0'
    annotationProcessor "com.jakewharton:butterknife-compiler:10.1.0"

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

2.2 set compile option java sdk target 1.8 for using lambda expression.

compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }

3. Add INTERNET uses permission in AndroidManifest.xml

  <uses-permission android:name="android.permission.INTERNET" />
  <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

Full project structure look as below figure

4. Let’s create a model class named YoutubeVideo.java

Define all model entities in POJO such as – id, title, videoId, and imageUrl etc.

package com.androidwave.youtuberecycler.model;

  public class YoutubeVideo {
    private String title;
    private Long id;
    private String videoId;
    private String imageUrl;

    public String getImageUrl() {
      return imageUrl;
    }

    public void setImageUrl(String imageUrl) {
      this.imageUrl = imageUrl;
    }

    public String getTitle() {
      return title;
    }

    public void setTitle(String title) {
      this.title = title;
    }

    public Long getId() {
      return id;
    }

    public void setId(Long id) {
      this.id = id;
    }

    public String getVideoId() {
      return videoId;
    }

    public void setVideoId(String videoId) {
      this.videoId = videoId;
    }
  }

5. BaseViewHolder is helper class for RecyclerView.

Now I’m creating a generics file for BaseViewHolder which extends RecyclerView.ViewHolder. Which help a lot fetching current position of items in RecyclerView Adapter.

package com.androidwave.youtuberecycler.base;

import android.view.View;
import androidx.recyclerview.widget.RecyclerView;

public abstract class BaseViewHolder extends RecyclerView.ViewHolder {

  private int mCurrentPosition;

  public BaseViewHolder(View itemView) {
    super(itemView);
  }

  protected abstract void clear();

  public void onBind(int position) {
    mCurrentPosition = position;
    clear();
  }

  public int getCurrentPosition() {
    return mCurrentPosition;
  }
}

6. Prepare XML layout for list item.

Go to res = > layout folder and creates a layout file named item_youtube_list.xml and paste below code. Finally, the RecyclerView items look like below image

<?xml version="1.0" encoding="utf-8"?>
<androidx.cardview.widget.CardView
    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:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="8dp"
    app:cardCornerRadius="6dp"
    app:cardElevation="6dp"
    >

  <androidx.constraintlayout.widget.ConstraintLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      >

    <TextView
        android:id="@+id/textViewTitle"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginEnd="8dp"
        android:layout_marginStart="16dp"
        android:layout_marginTop="16dp"
        android:letterSpacing="-0.02"
        android:lineSpacingExtra="5sp"
        android:text="TextView"
        android:textColor="@color/navy"
        android:textSize="18sp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:text="Was india better then south africa in current serise?"
        />

    <ImageView
        android:id="@+id/imageViewItem"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:scaleType="matrix"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/textViewTitle"
        />

    <com.pierfrancescosoffritti.youtubeplayer.player.YouTubePlayerView
        android:id="@+id/youtube_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:visibility="gone"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/textViewTitle"
        />

    <ImageView
        android:id="@+id/btnPlay"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginBottom="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        app:layout_constraintBottom_toBottomOf="@+id/imageViewItem"
        app:layout_constraintEnd_toEndOf="@+id/imageViewItem"
        app:layout_constraintStart_toStartOf="@+id/imageViewItem"
        app:layout_constraintTop_toTopOf="@+id/imageViewItem"
        app:srcCompat="@drawable/ic_play_button"
        />
  </androidx.constraintlayout.widget.ConstraintLayout>
</androidx.cardview.widget.CardView>

7. Now create a new class named YoutubeRecyclerAdapter.java.

package com.androidwave.youtuberecycler.adapter;

import android.app.Activity;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import androidx.annotation.NonNull;
import androidx.recyclerview.widget.RecyclerView;
import butterknife.BindView;
import butterknife.ButterKnife;
import com.androidwave.youtuberecycler.R;
import com.androidwave.youtuberecycler.base.BaseViewHolder;
import com.androidwave.youtuberecycler.model.YoutubeVideo;
import com.bumptech.glide.Glide;
import com.bumptech.glide.request.RequestOptions;
import com.pierfrancescosoffritti.youtubeplayer.player.AbstractYouTubePlayerListener;
import com.pierfrancescosoffritti.youtubeplayer.player.YouTubePlayerView;
import java.util.List;

public class YoutubeRecyclerAdapter extends RecyclerView.Adapter<BaseViewHolder> {

  public static final int VIEW_TYPE_NORMAL = 1;

  private List<YoutubeVideo> mYoutubeVideos;
  DisplayMetrics displayMetrics = new DisplayMetrics();

  public YoutubeRecyclerAdapter(List<YoutubeVideo> youtubeVideos) {
    mYoutubeVideos = youtubeVideos;
  }

  @NonNull
  @Override
  public BaseViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
    return new ViewHolder(LayoutInflater.from(parent.getContext())
        .inflate(R.layout.item_youtube_list, parent, false));
  }

  @Override
  public void onBindViewHolder(@NonNull BaseViewHolder holder, int position) {
    holder.onBind(position);
  }

  @Override
  public int getItemViewType(int position) {
    return VIEW_TYPE_NORMAL;
  }

  @Override
  public int getItemCount() {
    if (mYoutubeVideos != null && mYoutubeVideos.size() > 0) {
      return mYoutubeVideos.size();
    } else {
      return 1;
    }
  }

  public void setItems(List<YoutubeVideo> youtubeVideos) {
    mYoutubeVideos = youtubeVideos;
    notifyDataSetChanged();
  }

  public class ViewHolder extends BaseViewHolder {
    @BindView(R.id.textViewTitle)
    TextView textWaveTitle;
    @BindView(R.id.btnPlay)
    ImageView playButton;

    @BindView(R.id.imageViewItem)
    ImageView imageViewItems;
    @BindView(R.id.youtube_view)
    YouTubePlayerView youTubePlayerView;

    public ViewHolder(View itemView) {
      super(itemView);
      ButterKnife.bind(this, itemView);
    }

    protected void clear() {

    }

    public void onBind(int position) {
      super.onBind(position);
      final YoutubeVideo mYoutubeVideo = mYoutubeVideos.get(position);
      ((Activity) itemView.getContext()).getWindowManager()
          .getDefaultDisplay()
          .getMetrics(displayMetrics);
      int width = displayMetrics.widthPixels;
      if (mYoutubeVideo.getTitle() != null) {
        textWaveTitle.setText(mYoutubeVideo.getTitle());
      }

      if (mYoutubeVideo.getImageUrl() != null) {
        Glide.with(itemView.getContext())
            .load(mYoutubeVideo.getImageUrl()).
            apply(new RequestOptions().override(width - 36, 200))
            .into(imageViewItems);
      }
      imageViewItems.setVisibility(View.VISIBLE);
      playButton.setVisibility(View.VISIBLE);
      youTubePlayerView.setVisibility(View.GONE);

      playButton.setOnClickListener(view -> {
        imageViewItems.setVisibility(View.GONE);
        youTubePlayerView.setVisibility(View.VISIBLE);
        playButton.setVisibility(View.GONE);
        youTubePlayerView.initialize(
            initializedYouTubePlayer -> initializedYouTubePlayer.addListener(
                new AbstractYouTubePlayerListener() {
                  @Override
                  public void onReady() {
                    initializedYouTubePlayer.loadVideo(mYoutubeVideo.getVideoId(), 0);
                  }
                }), true);
      });
    }
  }
}

8. Open the Activity (MainActivity) and bind the views using @inject annotation using butter knife library.

@BindView(R.id.recyclerViewFeed)
RecyclerView recyclerViewFeed;
  @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);
    }

9. Prepare demo content for list.

private List<YoutubeVideo> prepareList() {
    ArrayList<YoutubeVideo> videoArrayList=new ArrayList<>();

    // add first item
    YoutubeVideo video1 = new YoutubeVideo();
    video1.setId(1l);
    video1.setImageUrl("https://i.ytimg.com/vi/zI-Pux4uaqM/maxresdefault.jpg");
    video1.setTitle(
        "Thugs Of Hindostan - Official Trailer | Amitabh Bachchan | Aamir Khan");
    video1.setVideoId("zI-Pux4uaqM");
    videoArrayList.add(video1);

    // add second item
    YoutubeVideo video2 = new YoutubeVideo();
    video2.setId(2l);
    video2.setImageUrl("https://i.ytimg.com/vi/8ZK_S-46KwE/maxresdefault.jpg");
    video2.setTitle(
        "Colors for Children to Learning with Baby Fun Play with Color Balls Dolphin...");
    video2.setVideoId("8ZK_S-46KwE");

    // add third item
    YoutubeVideo video3 = new YoutubeVideo();
    video3.setId(3l);
    video3.setImageUrl("https://i.ytimg.com/vi/8czMWUH7vW4/hqdefault.jpg");
    video3.setTitle("Air Hostess Accepts Marriage Proposal Mid-Air, Airline Fires her.");
    video3.setVideoId("8czMWUH7vW4");

    // add four item
    YoutubeVideo video4 = new YoutubeVideo();
    video4.setId(4l);
    video4.setImageUrl("https://i.ytimg.com/vi/YrQVYEb6hcc/maxresdefault.jpg");
    video4.setTitle("EXPERIMENT Glowing 1000 degree METAL BALL vs Gunpowder (100 grams)");
    video4.setVideoId("YrQVYEb6hcc");

    // add four item
    YoutubeVideo video5 = new YoutubeVideo();
    video5.setId(5l);
    video5.setImageUrl("https://i.ytimg.com/vi/S84Fuo2rGoY/maxresdefault.jpg");
    video5.setTitle("What happened after Jauhar of Padmavati");
    video5.setVideoId("S84Fuo2rGoY");

    videoArrayList.add(video1);
    videoArrayList.add(video2);
    videoArrayList.add(video3);
    videoArrayList.add(video4);
    return videoArrayList;
  }

10. Set the adapter over RecyclerView.

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);
    // prepare data for list
    List<YoutubeVideo> youtubeVideos = prepareList();
    mRecyclerAdapter = new YoutubeRecyclerAdapter(youtubeVideos);
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
    recyclerViewFeed.setLayoutManager(mLayoutManager);
    recyclerViewFeed.setItemAnimator(new DefaultItemAnimator());
    recyclerViewFeed.setAdapter(mRecyclerAdapter);
  }

11. Finally, MainActivity.java source look like this

package com.androidwave.youtuberecycler;

import android.os.Bundle;
import androidx.appcompat.app.AppCompatActivity;
import androidx.recyclerview.widget.DefaultItemAnimator;
import androidx.recyclerview.widget.LinearLayoutManager;
import androidx.recyclerview.widget.RecyclerView;
import butterknife.BindView;
import butterknife.ButterKnife;
import com.androidwave.youtuberecycler.adapter.YoutubeRecyclerAdapter;
import com.androidwave.youtuberecycler.model.YoutubeVideo;
import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity {

  @BindView(R.id.recyclerViewFeed)
  RecyclerView recyclerViewFeed;

  YoutubeRecyclerAdapter mRecyclerAdapter;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(this);
    // prepare data for list
    List<YoutubeVideo> youtubeVideos = prepareList();
    mRecyclerAdapter = new YoutubeRecyclerAdapter(youtubeVideos);
    RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
    recyclerViewFeed.setLayoutManager(mLayoutManager);
    recyclerViewFeed.setItemAnimator(new DefaultItemAnimator());
    recyclerViewFeed.setAdapter(mRecyclerAdapter);
  }

  private List<YoutubeVideo> prepareList() {
    ArrayList<YoutubeVideo> videoArrayList=new ArrayList<>();

    // add first item
    YoutubeVideo video1 = new YoutubeVideo();
    video1.setId(1l);
    video1.setImageUrl("https://i.ytimg.com/vi/zI-Pux4uaqM/maxresdefault.jpg");
    video1.setTitle(
        "Thugs Of Hindostan - Official Trailer | Amitabh Bachchan | Aamir Khan");
    video1.setVideoId("zI-Pux4uaqM");
    videoArrayList.add(video1);

    // add second item
    YoutubeVideo video2 = new YoutubeVideo();
    video2.setId(2l);
    video2.setImageUrl("https://i.ytimg.com/vi/8ZK_S-46KwE/maxresdefault.jpg");
    video2.setTitle(
        "Colors for Children to Learning with Baby Fun Play with Color Balls Dolphin...");
    video2.setVideoId("8ZK_S-46KwE");

    // add third item
    YoutubeVideo video3 = new YoutubeVideo();
    video3.setId(3l);
    video3.setImageUrl("https://i.ytimg.com/vi/8czMWUH7vW4/hqdefault.jpg");
    video3.setTitle("Air Hostess Accepts Marriage Proposal Mid-Air, Airline Fires her.");
    video3.setVideoId("8czMWUH7vW4");

    // add four item
    YoutubeVideo video4 = new YoutubeVideo();
    video4.setId(4l);
    video4.setImageUrl("https://i.ytimg.com/vi/YrQVYEb6hcc/maxresdefault.jpg");
    video4.setTitle("EXPERIMENT Glowing 1000 degree METAL BALL vs Gunpowder (100 grams)");
    video4.setVideoId("YrQVYEb6hcc");

    // add four item
    YoutubeVideo video5 = new YoutubeVideo();
    video5.setId(5l);
    video5.setImageUrl("https://i.ytimg.com/vi/S84Fuo2rGoY/maxresdefault.jpg");
    video5.setTitle("What happened after Jauhar of Padmavati");
    video5.setVideoId("S84Fuo2rGoY");

    videoArrayList.add(video1);
    videoArrayList.add(video2);
    videoArrayList.add(video3);
    videoArrayList.add(video4);
    return videoArrayList;
  }
}

Finally, we have learned youtube player in RecyclerView with the help of this example. Thanks a lot
