    this.list = list;

  }

  static class ViewHolder {
    protected TextView text;
    protected Button button;
  }

  @Override
  public View getView(int position, View convertView, ViewGroup parent) {
    View view = null;

    if (convertView == null) {
      LayoutInflater inflator = context.getLayoutInflater();
      view = inflator.inflate(R.layout.rowbuttonlayout, null);
      final ViewHolder viewHolder = new ViewHolder();
      viewHolder.text …
