使用sax在android中解析xml数据

Question

I have to develop one android xml parsing using sax app.

Here i displayed the category-name and article title for belonging category on single listview...its done well..

But my requirement is category name is display on gridview and article title is display on horizontal listview for below the corresponding category.

Here i have to use below code means am getting following error:

The method setAdapter(ListAdapter) in the type HorizontalListView is not applicable for the arguments (String)

Laptop.java:

public class Laptop {
   private String model;
private String brand;
public String getModel() {
    return model;
}
public void setModel(String model) {
    this.model = model;
}

public String getBrand() {
    return brand;
}
public void setBrand(String brand) {
    this.brand = brand;
}}

In SaxXMLHandler.java

 public void startElement(String uri, String localName, String qName,
        Attributes attributes) throws SAXException {
    // reset
    tempVal = "";
    if (qName.equalsIgnoreCase("Category")) {
        // create a new instance of Laptop
        laptop = new Laptop();
        laptop.setBrand(attributes.getValue("name"));
    }
    else  if (qName.equalsIgnoreCase("article")) {
        // create a new instance of Laptop
        article = new Laptop();
        article.setModel(attributes.getValue("title"));
    } 

In CustomListViewAdapter.java

    public class CustomListViewAdapter extends ArrayAdapter<Laptop> {
     Activity context;
     List<Laptop> laptops;

     public CustomListViewAdapter(Context context2, List<Laptop> laptops) {
     super(context2, R.layout.list_item, laptops);
    this.context = (Activity) context2;
    this.laptops = laptops;
}

/*private view holder class*/
private class ViewHolder {
    ImageView imageView;
    HorizontalListView txtModel;

    TextView txtBrand;
    TextView txtPrice;
}

public Laptop getItem(int position) {
    return laptops.get(position);
}

public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
    LayoutInflater inflater = context.getLayoutInflater();

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.list_item, null);
        holder = new ViewHolder();
        holder.txtModel = (HorizontalListView) convertView.findViewById(R.id.model);

        holder.txtBrand = (TextView) convertView.findViewById(R.id.brand);
      //  holder.txtPrice = (TextView) convertView.findViewById(R.id.price);
       // holder.imageView = (ImageView) convertView.findViewById(R.id.thumbnail);
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    Laptop laptop = (Laptop) getItem(position);
    // holder.txtModel.setText(laptop.getModel());
    holder.txtBrand.setText(laptop.getBrand());
   // holder.imageView.setImageBitmap(laptop.getImageBitmap());
   // holder.txtPrice.setText(laptop.getPrice() + "");

  holder.txtModel.setAdapter(laptop.getModel());
    return convertView;
}}

In HorizontalListView.java

public void setAdapter(ListAdapter adapter) {
    if(mAdapter != null) {
        mAdapter.unregisterDataSetObserver(mDataObserver);
   }
    mAdapter = adapter;
     mAdapter.registerDataSetObserver(mDataObserver);
    reset();
   }

am getting the above error in the below line:

holder.txtModel.setAdapter(laptop.getModel());

How can i resolve these ??? How can i get the article title on horizontal listview for below the corresponding category...
