Using Intent to parse Values from Adapter to Activity

Question

After following some tutorials I made an app that shows Youtube Videos of a specific Youtube playlist in listview.

How can I parse the corresponding video Id to play the video in my app itself using a VideoView

My PlaylistCardAdapter

    //  click listener to play the video
    holder.mThumbnailImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(view.getContext(), Activity2.class);
            intent.putExtra("VidId", video.getId());
            view.getContext().startActivity(intent);

        }
    });

My second Activity in which I want to parse the VideoId

 public class Activity2 extends YouTubeBaseActivity implements View.OnClickListener {
Button mbutton;
private YouTubePlayerView myouTubePlayerView;
private YouTubePlayer.OnInitializedListener monInitializedListener;

  String VidKey = getIntent().getExtras().getString("VidId");//error here as per logcat

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.player);myouTubePlayerView = (YouTubePlayerView) findViewById(R.id.youtube_player_view);
    monInitializedListener = new YouTubePlayer.OnInitializedListener() {

  @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
            youTubePlayer.loadVideo(VidKey);
        }

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

        }
    };

    mbutton = (Button) findViewById(R.id.button_play_youtube_video);
    mbutton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            myouTubePlayerView.initialize(YOUTUBE_API_KEY, monInitializedListener);
        }
    });
}

Error I'm getting

To play YouTube videos within your app you have integrate

YouTube Android Player API

in your project.

It will provide a custom view that you will add in your xml like this.

<com.google.android.youtube.player.YouTubePlayerView
            android:id="@+id/youtube_view"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="30dp" />

And for further implementation help you can follow this tutorial.

I didn't understand what parsing you are saying about . What is there to parse ? – Vivek Mishra Dec 15 '16 at 16:00
In my Second activity... how to get video id for youtubeplayer.loadVideo() using Intent – Gbenga A Dec 15 '16 at 16:16
While starting your second activity use putExtra method and for value use video.getId. To get value in next activity use getIntent.getExtra. – Vivek Mishra Dec 15 '16 at 16:18
Thanks and sorry for trouble .. I'll try and get back soon!! – Gbenga A Dec 15 '16 at 16:21
GetIntent will be null if you call it outside onCreate method . So put your getIntent code inside onCreate method – Vivek Mishra Dec 16 '16 at 05:56
Accept the answer if it helped – Vivek Mishra Dec 16 '16 at 06:02
