I want to show multiple YouTube videos in a Horizontal ScrollView. For that, I'm adding YouTubePlayerFragments dynamically. Here's the piece of my code:
//set videos
int count = 0;
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
for (final Video video : mVideos) {
//create an instance of a video fragment
final VideoFragment fragment = new VideoFragment();// VideoFragment extends YouTubePlayerFragment
Bundle bundle = new Bundle();
if (null != mVideos && 0 < mVideos.size()) {
bundle.putString(VideoFragment.KEY_VIDEO_KEY, video.getKey());
}
fragment.setArguments(bundle);
FrameLayout frameLayout = new FrameLayout(getActivity());
frameLayout.setLayoutParams(new FrameLayout.LayoutParams(900, 500));
frameLayout.setPadding(10, 0, 10, 0);
frameLayout.setId(12345 + ++count);
mLayoutTrailers.addView(frameLayout);//mLayoutTrailers is a LinearLayout inside my Horizontal ScrollView
transaction.add(frameLayout.getId(), fragment, VideoFragment.TAG + count);
}
transaction.commit();
I'm initializing the youtube player inside OnResume of my VideoFragment. And below is how the videos gets loaded.
It shows the lastly loaded video for all the players. I debugged - It initializes all the players with the first video, then all the players with the second video & so on until the last one.
The issue is already discussed here. There seems to be a work around with initializing the player inside "setUserVisibleHint(boolean isVisibleToUser)" in my VideoFragment in stead of OnResume(), but I don't know how to use that with my HorizontalScrollView
Is there a way I can load multiple YouTube videos in a Horizontal ScrollView?
Any sort of help will be appreciated!
I dont think it is possible to create multiple instance of YouTube Player Fragment as it is Singleton.
No matter how many instances you make they all gone be same and your horizontal scrollview will show thumbnail of last VideoFragment you added .
Alternatively you can give an illusion of multiple YouTube Fragment by showing video thumb and on click of thumb play the video with the help of youtube player
// get thumbnail image of that video by videoID
String videoThumbUrl="http://img.youtube.com/vi/"+videoId+"/0.jpg";
//Load thumb in viewpager/Hrizontal scrollview/Recycle View with the
//help of Picasso/Glide/UIL etc
Picasso.with(getActivity())
.load(videoThumbUrl)
.into(videoThumbImageView);
And then on click of thumb you can add youtube fragment in View container holding imageview and start playing video with the video id
videoThumbImageView.setOnClickListenr(..)
{...
//Add Youtube fragment in container and start playing video
}
This is just a pseudo code but you get and idea.
Edit
Added code for how to play and stop videos on tap of thumbnails.
I was offline so was unable to use YouTube fragment so I used Videoview to play random videos you can replace videoview with YouTube fragment and. Guranteed it still gone work great
Array list to hold list of videos
public static ArrayList<VideoModel> listOfVideos = new ArrayList<>();
Variable to keep track of current playing video
// Allows to remember the last item shown on screen
private int lastPosition = 0;
Recycler view item click listener
videoGridAdapter.setOnCardClickListner(new VideoGridAdapter.OnCardClickListner() {
@Override
public void OnCardClicked(View view, int position) {
//Make Lats Tapped item playing false
listOfVideos.get(lastPosition).setPlaying(false);
//Make current Tapped item playing true
listOfVideos.get(position).setPlaying(true);
// update pointer of last tapped video to current tapped video
lastPosition = position;
//LET RCYCLERVIEW ADAPTER DO THE MAGIC
videoGridAdapter.notifyDataSetChanged();
}
});
