5,872 PointsCode challenge Null Pointer Exception
The code challenge task 3 for Recyclerview Android gave me this error "java.lang.NullPointerException (Look around JavaTester.java line 129)". There aren't even 129 lines of code in the program.
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 static class GameViewHolder extends RecyclerView.ViewHolder{
public TextView mTitleLabel;
public GameViewHolder(View view){
super(view);
mTitleLabel= (TextView) view.findViewById(R.id.titleLabel);
}
}
}
