Usage

Add AAH_VideoImage to your xml file for single list item single_card.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.v7.widget.CardView
        android:id="@+id/card_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
       
       <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical">

             <FrameLayout
                android:layout_width="300dp"
                android:layout_height="150dp">

                <com.allattentionhere.autoplayvideos.AAH_VideoImage
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />

                <ImageView
                    android:id="@+id/img_vol"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:layout_gravity="right|bottom"
                    android:layout_margin="8dp"
                    android:src="@drawable/ic_unmute"/>
            </FrameLayout>

            <TextView
                android:id="@+id/tv"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:gravity="center" />
		
        </LinearLayout>
    </android.support.v7.widget.CardView>
</LinearLayout>

Add AAH_CustomRecyclerView to your Activity layout xml MainActivity.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <com.allattentionhere.autoplayvideos.AAH_CustomRecyclerView
        android:id="@+id/rv_home"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
	
</LinearLayout>

Set Adapter with following specifics:

1. Adapter should extend AAH_VideosAdapter.
2. ViewHolder should extend AAH_CustomViewHolder.
3. Set thumbnail image url and video url in onBindViewHolder method.

public class MyVideosAdapter extends AAH_VideosAdapter {

    private List<MyModel> list;
    Picasso picasso;

    public class MyViewHolder extends AAH_CustomViewHolder {
        final TextView tv;
	final ImageView img_vol,img_playback;
        boolean isMuted; //to mute/un-mute video (optional)
	
        public MyViewHolder(View x) {
            super(x);
            tv = ButterKnife.findById(x, R.id.tv);
	    img_vol = ButterKnife.findById(x, R.id.img_vol);
	    img_playback = ButterKnife.findById(x, R.id.img_playback);
        }
    }

    public MyVideosAdapter(List<MyModel> list_urls, Picasso p) {
        this.list = list_urls;
        this.picasso = p;
    }

    @Override
    public AAH_CustomViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.single_card, parent, false);
        return new MyViewHolder(itemView);
    }

    @Override
    public void onBindViewHolder(AAH_CustomViewHolder holder, int position) {
        ((MyViewHolder) holder).tv.setText(list.get(position).getName());

        //todo
        holder.setImageUrl(list.get(position).getImage_url());
        holder.setVideoUrl(list.get(position).getVideo_url());
        //load image/thumbnail into imageview
        if (list.get(position).getImage_url() != null && !list.get(position).getImage_url().isEmpty())
            picasso.load(holder.getImageUrl()).config(Bitmap.Config.RGB_565).into(holder.getAAH_ImageView());
    }
    
    @Override
    public int getItemCount() {
        return list.size();
    }

    @Override
    public int getItemViewType(int position) {
        return 0;
    }
}

Finally setActivity in your Activity before setting the adapter and (Optional) scroll programmatically to initiate videos on initial screen:

    recyclerView.setActivity(this); //todo before setAdapter
    recyclerView.setAdapter(mAdapter);

Play videos initially (Optional)

Call these two functions to start video playback when the screen launches and user hasn't scrolled.

recyclerView.smoothScrollBy(0,1);
recyclerView.smoothScrollBy(0,-1);

Play only 1st video (Optional)

Setting this parameter will play video only in 1st completely visible RecyclerView ViewHolder.

recyclerView.setPlayOnlyFirstVideo(true); // false by default

Download videos to local storage (Optional)

You can start downloading video in background on viewholder loaded. You can change download path.

recyclerView.setDownloadPath(Environment.getExternalStorageDirectory() + "/MyVideo"); //optional
recyclerView.setDownloadVideos(true); // false by default

Optionally you can start pre-downloading all the videos by passing list of URLs to function as below:

List<String> urls = new ArrayList<>();
 for (MyModel object : modelList) {
     if (object.getVideo_url() != null && object.getVideo_url().endsWith(".mp4"))
         urls.add(object.getVideo_url());
 }
recyclerView.preDownload(urls);

Add below permission to AndroidManifest.xml. Ask for runtime permission in devices on Marshmallow and above.

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

Remove check for .mp4 (Optional)

By default it checks for url to end with .mp4 else it is not considered as video URL. You can override this by setting parameter as below. Please use this with caution and make sure you provide video URL only.

recyclerView.setCheckForMp4(false); // true by default

Pause videos manually (Optional)

Call the following method to stop the videos when Activity/Fragment stops (User receives call, minimizes app etc)

    @Override
    protected void onStop() {
        super.onStop();
        recyclerView.stopVideos();
    }

Resume videos when app resumes (Optional)

Call the following method to resume videos when App resumes (opening app after minimizing it, etc)

    @Override
    protected void onResume() {
        super.onResume();
        recyclerView.playAvailableVideos(0);
    }

Play partially visible video (Optional)

Call the following method to set the percentage of view that needs to be visible for video to start playing.

    recyclerView.setVisiblePercent(50);

Get callbacks when videos starts and pauses

You can override the below methods of AAH_CustomViewHolder to get callback when video starts to play or pauses.

	@Override
        public void videoStarted() {
            super.videoStarted();
            img_playback.setImageResource(R.drawable.ic_pause);
            if (isMuted) {
                muteVideo();
                img_vol.setImageResource(R.drawable.ic_mute);
            } else {
                unmuteVideo();
                img_vol.setImageResource(R.drawable.ic_unmute);
            }
        }
        @Override
        public void pauseVideo() {
            super.pauseVideo();
            img_pla
