This library is created with the purpose to implement recyclerview with videos easily.
It is targeted at solving following problems:
- Flicker when scrolling.
- 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.
- Mute/Un-mute videos.
- Option to play only first visible video.
- Download videos to local storage in background for faster loading.
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.allattentionhere:autoplayvideos:0.2.0'
}Or Maven
<dependency>
<groupId>com.allattentionhere</groupId>
<artifactId>autoplayvideos</artifactId>
<version>0.2.0</version>
<type>pom</type>
</dependency>Add below permissions to AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
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:
- Adapter should extend
AAH_VideosAdapter. - ViewHolder should extend
AAH_CustomViewHolder. - Set thumbnail image url and video url in
onBindViewHoldermethod.
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);
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);
Setting this parameter will play video only in 1st completely visible RecyclerView ViewHolder.
recyclerView.setPlayOnlyFirstVideo(true); // false by default
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" />
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
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();
}
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);
}
Call the following method to set the percentage of view that needs to be visible for video to start playing.
recyclerView.setVisiblePercent(50);
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);
}
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);
}
}
});
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 by adding below code in onBindViewHolder:
holder.setLooping(true); //optional - true by default
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 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);
}
}
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.
It is recommended to use Cloudinary.com to host your videos as it provides easy thumbnail-generation and resizing/cropping videos on-the-fly.
