Android ViewHolder pattern for smooth scrolling of ListView

private class MyAdapter extends ArrayAdapter<Object> {

    private final Context mContext;

    public MyAdapter(Context context) {
        super(context, 0);
        mContext = context;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = convertView;
        ViewHolder holder; // to reference the child views for later actions

        // Always check first if convertView already exists or not,
        // so that we can reuse it instead of inflating a new layout every time.
        if (view == null) {
            view = LayoutInflater.from(mContext).inflate(R.layout.my_layout, parent, false);
            
            holder = new ViewHolder();
            holder.view01 = (View) view.findViewById(R.id.view01);
            holder.view02 = (View) view.findViewById(R.id.view02);
            view.setTag(holder);
        } else {
            holder = (ViewHolder) view.getTag();

            // Set new view properties if necessary, or simply return convertView.
            Object obj = getItem(position);

            ...
        }

    return view;
}

private static class ViewHolder {
    public View view01;
    public View view02;
}
