ExoPlayer in RecyclerView in android

Google+ Pinterest LinkedIn Tumblr

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 another article we saw how to play audio, video from SD card (local) as well, So 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 app is there.

Before starting code, Think about the problem statement. Basically, The following major challenges for us to implementing ExoPlayer in RecyclerView.

  • The 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 a new 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

how to play youtube player in recylerview

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 
  • Get 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];
        }
    }

        rowParent = null;

}

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

Create a class name is VideoInfo.java

Go to the src folder and create the model folder for separating all model class. Inside create a new class with name VideoInfo.java. this is a POJO class that hold getter and setter of title and cover image URL . and media URL

package com.androidwave.exoplayer.model;

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

Create adapter class names with VideoRecyclerViewAdapter.java.

    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));

Lets add RecyclerView inside XML file

If you selected some default template while creating a project, MainActivity.java and activity_main.xml class will automatically be created.

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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="match_parent"
    tools:context=".MainActivity">

    <com.androidwave.exoplayer.ui.ExoPlayerRecyclerView
        android:id="@+id/recyclerViewFeed"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#dedede"
        android:dividerHeight="8dp" />

</android.support.constraint.ConstraintLayout>

Now prepare video array list

For displaying data on RecyclerView We have to prepare a demo content.

    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);

    }
