Build android app with youtube playlist
Below code snippets will explain how to integrate Youtube Playlist in our Android Application to make a Youtube Player. This app will retrieve playlist from youtube API and show it in list. Onclick of the videos will play the videos.
Get youtube playlist from youtube API by passing playlist string in a thread.
private void searchOnYoutube(final String playList){ new Thread(){ public void run(){ YoutubeConnector yc = new YoutubeConnector(SearchActivity.this); //searchResults = yc.search(keywords); searchResults = yc.playList(playList); handler.post(new Runnable(){ public void run(){ updateVideosFound(); } }); } }.start(); }
Get list of thumbnail image, title and description of the playlist
private void updateVideosFound(){ ArrayAdapter<VideoItem> adapter = new ArrayAdapter<VideoItem>(getApplicationContext(), R.layout.video_item, searchResults){ @Override public View getView(int position, View convertView, ViewGroup parent) { if(convertView == null){ convertView = getLayoutInflater().inflate(R.layout.video_item, parent, false); } ImageView thumbnail = (ImageView)convertView.findViewById(R.id.video_thumbnail); TextView title = (TextView)convertView.findViewById(R.id.video_title); TextView description = (TextView)convertView.findViewById(R.id.video_description); VideoItem searchResult = searchResults.get(position); Picasso.with(getApplicationContext()).load(searchResult.getThumbnailURL()).into(thumbnail); title.setText(searchResult.getTitle()); description.setText(searchResult.getDescription()); return convertView; } }; videosFound.setAdapter(adapter); }
Connect to youtube API and get details
public YoutubeConnector(Context context) { youtube = new YouTube.Builder(new NetHttpTransport(), new JacksonFactory(), new HttpRequestInitializer() { @Override public void initialize(HttpRequest hr) throws IOException {} }).setApplicationName(context.getString(R.string.app_name)).build(); try{ query = youtube.search().list("id,snippet"); query.setKey(KEY); query.setType("playlist"); query.setFields("items(id/playlistId,snippet/title,snippet/description,snippet/thumbnails/default/url)"); playListItemList = youtube.playlistItems().list("id,contentDetails,snippet,status"); playListItemList.setKey(KEY); playListItemList.setFields("items(id,status/privacyStatus,snippet/description,snippet(title,thumbnails/default/url),contentDetails)"); playListItemList.setMaxResults((long) 50); }catch(IOException e){ Log.d("YC", "Could not initialize: "+e); } }
Store playlist items in list
public List<VideoItem> search(String keywords){ query.setQ(keywords); try{ SearchListResponse response = query.execute(); List<SearchResult> results = response.getItems(); List<VideoItem> items = new ArrayList<VideoItem>(); for(SearchResult result:results){ VideoItem item = new VideoItem(); item.setTitle(result.getSnippet().getTitle()); item.setDescription(result.getSnippet().getDescription()); item.setThumbnailURL(result.getSnippet().getThumbnails().getDefault().getUrl()); item.setId(result.getId().getVideoId()); items.add(item); } return items; }catch(IOException e){ Log.d("YC", "Could not search: "+e); return null; } } public List<VideoItem> playList(String playList) { //final String[] playlistIds = params[0]; try { playListItemList.setPlaylistId(playList); PlaylistItemListResponse playlistItemListResponse = null; playlistItemListResponse = playListItemList.execute(); List<VideoItem> items = new ArrayList<VideoItem>(); for (int i=0;i<playlistItemListResponse.getItems().size();i++){ VideoItem item = new VideoItem(); item.setTitle(playlistItemListResponse.getItems().get(i).getSnippet().getTitle()); item.setDescription(playlistItemListResponse.getItems().get(i).getSnippet().getDescription()); item.setThumbnailURL(playlistItemListResponse.getItems().get(i).getSnippet().getThumbnails().getDefault().getUrl().replace("default","hqdefault")); //item.setThumbnailURL(playlistItemListResponse.getItems().get(i).getSnippet().getThumbnails().getDefault().getUrl()); item.setId(playlistItemListResponse.getItems().get(i).getContentDetails().getVideoId()); items.add(item); } return items; } catch (IOException e) { e.printStackTrace(); return null; } }
Add onclicklistner and onclick of video from playlist play the video
private void addClickListener(){ videosFound.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> av, View v, int pos, long id) { Intent intent = new Intent(getApplicationContext(), PlayerActivity.class); intent.putExtra("VIDEO_ID", searchResults.get(pos).getId()); startActivity(intent); } }); }
public class PlayerActivity extends YouTubeBaseActivity implements OnInitializedListener { private YouTubePlayerView playerView; @Override protected void onCreate(Bundle bundle) { super.onCreate(bundle); setContentView(R.layout.activity_player); playerView = (YouTubePlayerView)findViewById(R.id.player_view); playerView.initialize(YoutubeConnector.KEY, this); } @Override public void onInitializationFailure(Provider provider, YouTubeInitializationResult result) { Toast.makeText(this, getString(R.string.failed), Toast.LENGTH_LONG).show(); } @Override public void onInitializationSuccess(Provider provider, YouTubePlayer player, boolean restored) { if(!restored){ player.cueVideo(getIntent().getStringExtra("VIDEO_ID")); } } }
