Error with mediaPlayer.create(this, R.raw.sound) when not in onCreate

Question

I am working on an app that is basically a music library and for each song, when you press button play, the song starts playing. For the moment, my library has 3 items and I am trying to play "sound.mp3", which is in res/raw, for the 3 of them (for the moment).

My problem is when I try to reference the clip, I have a red underline under "this, R.raw.sound". I saw that in most cases "create" is called in onCreate, but in my case, this class in not an activity so I cannot do that ...

Can you guys help me with that? :)

    public class ClipsAdapter extends RecyclerView.Adapter<ClipsAdapter.MyViewHolder> {

private final List<Clips> clip2 = Arrays.asList(
        new Clips("Clip 1", "Artist 1"),
        new Clips("Clip 2", "Artist 2"),
        new Clips("Clip 3", "Artist 3")
);

public class MyViewHolder extends RecyclerView.ViewHolder {

    private final TextView title;
    private final TextView author;
    private final ImageView play;

    private Clips currentClip;
    MediaPlayer mediaPlayer = new MediaPlayer();

    public MyViewHolder(final View itemView) {
        super(itemView);

        title = ((TextView) itemView.findViewById(R.id.title));
        author = ((TextView) itemView.findViewById(R.id.author));
        play = ((ImageView) itemView.findViewById(R.id.play));
    }

    public void display(RandomClips RandomClip) {
        currentRandomClip = RandomClip;
        title.setText(RandomClip.title);
        author.setText(RandomClip.author);
        play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d(TAG, "Play clip: " + currentClip.title);
                mediaPlayer.create(this, R.raw.sound);

                if (mediaPlayer.isPlaying())
                {
                    mediaPlayer.stop();
                    mediaPlayer.reset();
                    Log.d(TAG, currentRandomClip.title + " has stopped");
                }
                else
                {
                    mediaPlayer.start();
                    Log.d(TAG, currentRandomClip.title + " is playing");
                }
            }
        });
    }
}

}

Answer 1

mediaPlayer.create() requests for a context and the file to play. The 'this' you are passing as an argument is not a Context (you are in an anonymous class) and therefore you get an error.
You should pass a context. Simply pass your activity's context when instantiating your ClipsAdapter.

So in your activity instantiate your adapter :

clipsAdapter = new ClipsAdapter(this); 

In your ClipsAdapter class, create a constructor with one parameter :

public ClipsAdapter(YourActivity activity) {
    this.activity = activity;
}

Finally :

mediaPlayer.create(activity, R.raw.sound);
