This library is created with the purpose to implement recyclerview with videos easily.
It is targeted at solving following problems:

- Lag or skipping frames when video starts.
- OutOfMemory errors.
And it has following features:
- Auto-play videos when in view.
- Auto-pause videos when not in view or partially in view.

Gradle
Step 1. Add the jCenter repository to your project-level build.gradle file
allprojects {
repositories {
jcenter()
}
}Step 2. Add the dependency to your app-level build.gradle file:
dependencies {
compile 'com.robert.autoplayvideo:0.1.2'
}Or Maven
<dependency>
<groupId>com.robert</groupId>
<artifactId>autoplayvideo</artifactId>
<version>0.1.2</version>
<type>pom</type>
</dependency>Usage
Add 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.robert.autoplayvideo.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 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.robert.autoplayvideo.CustomRecyclerView
android:id="@+id/rv_home"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
Set Adapter with following specifics:
- Adapter should extend
VideosAdapter. - ViewHolder should extend
CustomViewHolder. - Set thumbnail image url and video url in
onBindViewHoldermethod.
public class MyVideosAdapter extends VideosAdapter {
private List<MyModel> list;
Picasso picasso;
public class MyViewHolder extends 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 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(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.getImageView());
}
@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 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);
Note: Do not forget to add WRITE_EXTERNAL_STORAGE permission in the Manifest file and also ask for runtime permission in devices above Marshmallow.
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
Get callbacks when videos starts and pauses
You can override the below methods of 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
