In the previous tutorial, we demonstrate video streaming over the Internet using ExoPlayer. Somehow you missed previous articles you must read this ExoPlayer in Android for better understanding. In a previous blog, you get an idea about ExoPlayer core functionality, DASH and UI library module.

I hope you read my previous tutorials(I can assume you have basic knowledge about ExoPlayer). In this tutorial, I will describe how to implement video playback in the RecyclerView Android. Just like some popular application eg. Magisto, Facebook, Twitter, Instagram.

This article based on ExoPlayer. In case some things miss in this article download full source and a working sample apk is there.

Before starting to think in 2 min what we needed to solve.

  • First problem is managing ExoPlayer playback
  • Second is we need to know which view on the scrolled list is currently active. So we can initialize and release ExoPlayer intense in RecylerView
  • Create Project

    Simply go to file menu and create a project and add the ExoPlayer dependency in build.gradle.

        implementation 'com.google.android.exoplayer:exoplayer:2.7.3'
        implementation 'org.jsoup:jsoup:1.10.3'
    

    The complete project hierarchy seems like image

    ExoPlayer in RecyclerView in android

    Create a custom RecyclerView with ExoPlayerRecyclerView name

    Now comes in first problem is

    how to manage ExoPlayer playback?

    Create a class ExoPlayerRecyclerView.java which extend RecyclerView
    Furthermore we fetch start position and end position of view from LayoutManager after that calculate target position.
    Here now on target position, we will add ExoPlayerView and set ExoPlayer.

      //play the video in the row
        public void playVideo() {
            int startPosition = ((LinearLayoutManager) getLayoutManager()).findFirstVisibleItemPosition();
            int endPosition = ((LinearLayoutManager) getLayoutManager()).findLastVisibleItemPosition();
    
            if (endPosition - startPosition > 1) {
                endPosition = startPosition + 1;
            }
    
            if (startPosition < 0 || endPosition < 0) {
                return;
            }
    
            int targetPosition;
            if (startPosition != endPosition) {
                int startPositionVideoHeight = getVisibleVideoSurfaceHeight(startPosition);
                int endPositionVideoHeight = getVisibleVideoSurfaceHeight(endPosition);
                targetPosition = startPositionVideoHeight > endPositionVideoHeight ? startPosition : endPosition;
            } else {
                targetPosition = startPosition;
            }
    
            if (targetPosition < 0 || targetPosition == playPosition) {
                return;
            }
            playPosition = targetPosition;
            if (videoSurfaceView == null) {
                return;
            }
            videoSurfaceView.setVisibility(INVISIBLE);
            removeVideoView(videoSurfaceView);
    
            // get target View targetPosition in RecyclerView
            int at = targetPosition - ((LinearLayoutManager) getLayoutManager()).findFirstVisibleItemPosition();
    
            View child = getChildAt(at);
            if (child == null) {
                return;
            }
    
            VideoRecyclerViewAdapter.ViewHolder holder
                    = (VideoRecyclerViewAdapter.ViewHolder) child.getTag();
            if (holder == null) {
                playPosition = -1;
                return;
            }
            mCoverImage = holder.mCover;
            FrameLayout frameLayout = holder.itemView.findViewById(R.id.video_layout);
            frameLayout.addView(videoSurfaceView);
            addedVideo = true;
            rowParent = holder.itemView;
            videoSurfaceView.requestFocus();
            // Bind the player to the view.
            videoSurfaceView.setPlayer(player);
    
            // Measures bandwidth during playback. Can be null if not required.
            DefaultBandwidthMeter defaultBandwidthMeter = new DefaultBandwidthMeter();
            // Produces DataSource instances through which media data is loaded.
    
            DataSource.Factory dataSourceFactory = new DefaultDataSourceFactory(appContext,
                    Util.getUserAgent(appContext, "android_wave_list"), defaultBandwidthMeter);
            // This is the MediaSource representing the media to be played.
            String uriString = videoInfoList.get(targetPosition).getUrl();
            if (uriString != null) {
                MediaSource videoSource = new ExtractorMediaSource.Factory(dataSourceFactory)
                        .createMediaSource(Uri.parse(uriString));
                // Prepare the player with the source.
                player.prepare(videoSource);
                player.setPlayWhenReady(true);
            }
    
    
        }
    

    Now comes in the second problem get visible Video Surface scrolled list.

      private int getVisibleVideoSurfaceHeight(int playPosition) {
            int at = playPosition - ((LinearLayoutManager) getLayoutManager()).findFirstVisibleItemPosition();
    
            View child = getChildAt(at);
            if (child == null) {
                return 0;
            }
    
            int[] location01 = new int[2];
            child.getLocationInWindow(location01);
    
            if (location01[1] < 0) {
                return location01[1] + videoSurfaceDefaultHeight;
            } else {
                return screenDefaultHeight - location01[1];
            }
        }

                }
    
                @Override
                public void onRepeatModeChanged(int repeatMode) {
    
                }
    
                @Override
                public void onShuffleModeEnabledChanged(boolean shuffleModeEnabled) {
    
                }
    
                @Override
                public void onPlayerError(ExoPlaybackException error) {
    
                }
    
                @Override
                public void onPositionDiscontinuity(int reason) {
    
                }
    
                @Override
                public void onPlaybackParametersChanged(PlaybackParameters playbackParameters) {
    
                }
    
                @Override
                public void onSeekProcessed() {
    
                }
            });
        }
    
        public void onPausePlayer() {
            if (videoSurfaceView != null) {
                removeVideoView(videoSurfaceView);
                player.release();
                videoSurfaceView = null;
            }
        }
    
        public void onRestartPlayer() {
            if (videoSurfaceView == null) {
                playPosition = -1;
                playVideo();
            }
        }
    
        /**
         * release memory
         */
        public void onRelease() {
    
            if (player != null) {
                player.release();
                player = null;
            }
    
            rowParent = null;
        }
    
    
    }
    
    

    Now ExoPlayerRecyclerView.java component is ready to use. Now I will explain how to use this component.

    Create a VideoInfo.java model class

    public class VideoInfo {
        private int mId;
        private String mTitle;
        private String mUrl;
        private String mCoverUrl;
        private String mUserHandle;
    
        public String getUserHandle() {
            return mUserHandle;
        }
    
        public void setUserHandle(String mUserHandle) {
            this.mUserHandle = mUserHandle;
        }
    
        public int getId() {
            return mId;
        }
    
        public void setId(int mId) {
            this.mId = mId;
        }
    
        public String getTitle() {
            return mTitle;
        }
    
        public void setTitle(String mTitle) {
            this.mTitle = mTitle;
        }
    
        public String getUrl() {
            return mUrl;
        }
    
        public void setUrl(String mUrl) {
            this.mUrl = mUrl;
        }
    
        public String getCoverUrl() {
            return mCoverUrl;
        }
    
        public void setCoverUrl(String mCoverUrl) {
            this.mCoverUrl = mCoverUrl;
        }
    } 
    

    Create a RecyclerView adapter and bind views with holder

    package com.androidwave.exoplayer.adapter;
    
    import android.support.annotation.NonNull;
    import android.support.v7.widget.RecyclerView;
    import android.view.LayoutInflater;

    import java.util.List;
    
    import butterknife.BindView;
    import butterknife.ButterKnife;
    import butterknife.OnClick;
    
    public class VideoRecyclerViewAdapter extends RecyclerView.Adapter<BaseViewHolder> {
    
        public static final int VIEW_TYPE_EMPTY = 0;
        public static final int VIEW_TYPE_NORMAL = 1;
    
        private List<VideoInfo> mInfoList;
    
        public VideoRecyclerViewAdapter(List<VideoInfo> infoList) {
            mInfoList = infoList;
        }
    
        @NonNull
        @Override
        public BaseViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
            switch (viewType) {
                case VIEW_TYPE_NORMAL:
                    return new ViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item_layout, parent, false));
                case VIEW_TYPE_EMPTY:
                    return new EmptyViewHolder(LayoutInflater.from(parent.getContext()).inflate(R.layout.item_empty_view, parent, false));
                default:
                    return null;
            }
        }
    
        @Override
        public void onBindViewHolder(@NonNull BaseViewHolder holder, int position) {
            holder.onBind(position);
        }
    
    
        @Override
        public int getItemViewType(int position) {
            if (mInfoList != null && mInfoList.size() > 0) {
                return VIEW_TYPE_NORMAL;
            } else {
                return VIEW_TYPE_EMPTY;
            }
        }
    
        @Override
        public int getItemCount() {
            if (mInfoList != null && mInfoList.size() > 0) {
                return mInfoList.size();
            } else {
                return 1;
            }
        }
    
    
    
        public void onRelease() {
            if (mInfoList != null) {
                mInfoList.clear();
                mInfoList = null;
            }
        }
    
        public class ViewHolder extends BaseViewHolder {
            @BindView(R.id.textViewTitle)
            TextView textViewTitle;
            @BindView(R.id.userHandle)
            TextView userHandle;
            @BindView(R.id.video_layout)
            public FrameLayout videoLayout;
            @BindView(R.id.cover)
            public ImageView mCover;
            public final View parent;
    
    
            public ViewHolder(View itemView) {
                super(itemView);
                ButterKnife.bind(this, itemView);
                parent = itemView;
            }
    
            protected void clear() {
    
            }
    
            public void onBind(int position) {
                super.onBind(position);
                parent.setTag(this);
                VideoInfo videoInfo = mInfoList.get(position);
                textViewTitle.setText(videoInfo.getTitle());
                userHandle.setText(videoInfo.getUserHandle());
                Glide.with(itemView.getContext())
                        .load(videoInfo.getCoverUrl()).apply(new RequestOptions().optionalCenterCrop())
                        .into(mCover);
            }
        }
    
        public class EmptyViewHolder extends BaseViewHolder {
    
            @BindView(R.id.btn_retry)
            Button retryButton;
    
            @BindView(R.id.tv_message)
            TextView messageTextView;
    
            public EmptyViewHolder(View itemView) {
                super(itemView);
                ButterKnife.bind(this, itemView);
                itemView.setVisibility(View.GONE);
            }
    
            @Override
            protected void clear() {
    
            }
    
            @OnClick(R.id.btn_retry)
            void onRetryClick() {
    
            }
        }
    }
    
    

    Now prepare video array list

       
      private void prepareVideoList() {
            VideoInfo videoInfo = new VideoInfo();
            videoInfo.setId(1);
            videoInfo.setUserHandle("@h.pandya");
            videoInfo.setTitle("Do you think the concept of marriage will no longer exist in the future?");
            videoInfo.setCoverUrl("https://androidwave.com/media/images/exo-player-in-recyclerview-in-android-1.png");
            videoInfo.setUrl("https://androidwave.com/media/androidwave-video-1.mp4");
    
            VideoInfo videoInfo2 = new VideoInfo();
            videoInfo2.setId(2);
            videoInfo2.setUserHandle("@hardik.patel");
            videoInfo2.setTitle("If my future husband doesn't cook food as good as my mother should I scold him?");
            videoInfo2.setCoverUrl("https://androidwave.com/media/images/exo-player-in-recyclerview-in-android-2.png");
            videoInfo2.setUrl("https://androidwave.com/media/androidwave-video-2.mp4");
    
            VideoInfo videoInfo3 = new VideoInfo();
            videoInfo3.setId(3);
            videoInfo3.setUserHandle("@arun.gandhi");
            videoInfo3.setTitle("Give your opinion about the Ayodhya temple controversy.");
            videoInfo3.setCoverUrl("https://androidwave.com/media/images/exo-player-in-recyclerview-in-android-3.png");
            videoInfo3.setUrl("https://androidwave.com/media/androidwave-video-3.mp4");
    
            VideoInfo videoInfo4 = new VideoInfo();
            videoInfo4.setId(4);
            videoInfo4.setUserHandle("@sachin.patel");
            videoInfo4.setTitle("When did kama founders find sex offensive to Indian traditions");
            videoInfo4.setCoverUrl("https://androidwave.com/media/images/exo-player-in-recyclerview-in-android-4.png");
            videoInfo4.setUrl("https://androidwave.com/media/androidwave-video-6.mp4");
    
            VideoInfo videoInfo5 = new VideoInfo();
            videoInfo5.setId(5);
            videoInfo5.setUserHandle("@monika.sharma");
            videoInfo5.setTitle("When did you last cry in front of someone?");
            videoInfo5.setCoverUrl("https://androidwave.com/media/images/exo-player-in-recyclerview-in-android-5.png");
            videoInfo5.setUrl("https://androidwave.com/media/androidwave-video-5.mp4");
    
            videoInfoList.add(videoInfo);
            videoInfoList.add(videoInfo2);
            videoInfoList.add(videoInfo3);
            videoInfoList.add(videoInfo4);
            videoInfoList.add(videoInfo5);
            videoInfoList.add(videoInfo);
            videoInfoList.add(videoInfo2);
            videoInfoList.add(videoInfo3);
            videoInfoList.add(videoInfo4);
            videoInfoList.add(videoInfo5);
    
        }
    

    Finally main actvity looks like

    1. Hello Sir,
      I want to full source code exoplayer in Recylerview and Autoplayback.

      Thanks!!
      Hitesh

    2. What if all the items in my RecyclerView are not videos? How can I modify the ExoPlayerRecyclerView to identify the rows which have videos and play them accordingly? Any help would be great 🙂

      • admin Reply

        Hi Darshan, Do not set video player view in non video item then ExoPlayer RecyclerView works as normal recyclerview video item

    3. Darshan Pania Reply

      How can I use this when I am using multiple viewholders in my recycle view? Any suggestion would help

      • admin Reply

        Sure, as my previous answer you can set only player in Video View holder only
