无法在ViewHolder内设置自定义字体

我已经尝试了在stackoverflow上可以找到的一切,但似乎没有任何效果。

问题是我无法更改CardViewLayout中任何TextView的字体。

我尝试了xml中的字体系列和文本外观 我通过这样做改变了它,但我得到了错误 无法解析符号“itemView”

代码:

public class cardAdapter extends ArrayAdapter<cardModel> {

public cardAdapter(Context context) {
    super(context, 0);
}

@Override
public View getView(int position, View contentView, ViewGroup parent) {
    ViewHolder holder;

    if (contentView == null) {
        LayoutInflater inflater = LayoutInflater.from(getContext());
        contentView = inflater.inflate(R.layout.card_layout, parent, false);
        holder = new ViewHolder(contentView);
        contentView.setTag(holder);
    } else {
        holder = (ViewHolder) contentView.getTag();
    }

    cardModel spot = getItem(position);

    holder.title.setText(spot.title);
    holder.description.setText(spot.description);
    Glide.with(getContext()).load(spot.url).into(holder.image);

    return contentView;
}

private static class ViewHolder {

    public TextView title;
    public TextView description;
    public ImageView image;

    Typeface customTypeOne = Typeface.createFromAsset(itemView.getContext().getAssets(), "fonts/typefaceone.ttf");

    public ViewHolder(View view) {
        this.title = (TextView) view.findViewById(R.id.title);
        title.setTypeface(customTypeOne);
        this.description = (TextView) view.findViewById(R.id.description);
        this.image = (ImageView) view.findViewById(R.id.image);
        }
    }
}
