Android Android Lists and Adapters (2015) Lists with RecyclerViews Creating a RecyclerView ViewHolder

Having trouble with third challenge

I can't seem to pass the third challenge in this exercise. I keep running into the error: "In the view holder, you must call 'findViewById()' on the view passed in." I'm not sure which ID to put into the findViewById?

GameAdapter.java
public class GameAdapter extends RecyclerView.Adapter<GameAdapter.GameViewHolder> {

    private Game[] mGames;

    public GameAdapter(Game[] games) {
        mGames = games;
    }

    @Override
    public GameViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return null;
    }

    @Override
    public void onBindViewHolder(GameViewHolder holder, int position) {
        // code omitted for brevity
    }

    @Override
    public int getItemCount() {
        return 0;
    }

    /* Add your code here */
  public class GameViewHolder extends RecyclerView.ViewHolder{
    public TextView mTitleLabel;
    public GameViewHolder(View v){
      mTitleLabel = findViewById(R.id.titleLabel);      

    }
  }

}

Hi Zach you were almost close but you forgot to add to cast your view to a TextView and also adding the itemView on this line "mTitleLabel = findViewById(R.id.titleLabel);" so it should look like:

public class GameViewHolder extends RecyclerView.ViewHolder{

     public TextView mTitleLabel;

     public GameViewHolder(View itemView) {
     mTitleLabel = (TextView) itemView.findViewById(R.id.titleLabel);  
}

}

Happy Coding!
