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_playback.setImageResource(R.drawable.ic_play);
        }

Play or pause videos manually

You can allow the user to play or pause any video by adding below code in onBindViewHolder:

    ((MyViewHolder) holder).img_playback.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (holder.isPlaying()) {
                    holder.pauseVideo();
                    holder.setPaused(true);
                } else {
                    holder.playVideo();
                    holder.setPaused(false);
                }
            }
        });

Mute or Unmute the videos

Video can be muted/unmuted by adding below code in onBindViewHolder:

    holder.getAah_vi().setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (((MyViewHolder) holder).isMuted) {
                    holder.unmuteVideo();
                    ((MyViewHolder) holder).img_vol.setImageResource(R.drawable.ic_unmute);
                } else {
                    holder.muteVideo();
                    ((MyViewHolder) holder).img_vol.setImageResource(R.drawable.ic_mute);
                }
                ((MyViewHolder) holder).isMuted = !((MyViewHolder) holder).isMuted;
            }
        });

Set looping on videos

Set looping on videos by adding below code in onBindViewHolder:

holder.setLooping(true); //optional - true by default

Cache Videos (Optional)

It is recommended to setDownloadVideos(value) to true. However if you do not want to use this option, we recommend you to use AndroidVideoCache library. Here is how you can use it along with our library:

Initilize HttpProxyCacheServer

Initilize HttpProxyCacheServer in your Application class and register Application class in your Manifest file.

public class MyApplication extends Application {
    private static HttpProxyCacheServer proxy;

    public static HttpProxyCacheServer getProxy() {
        return proxy;
    }

    @Override
    public void onCreate() {
        super.onCreate();
        proxy = new HttpProxyCacheServer(this);
    }
}   

Set proxy video URL

In your VideosAdapter, set the Video URL as follows:

holder.setVideoUrl(MyApplication.getProxy().getProxyUrl(list.get(position).getVideo_url()+"")); // url should not be null

You can also use advanced options for caching that the library supports. Refer to their documentation for the same.

Use Cloudinary (Optional)

It is recommended to use Cloudinary.com to host your videos as it provides easy thumbnail-generation and resizing/cropping videos on-the-fly.
