android:layout_width="fill_parent"
android:layout_height="fill_parent"

/>
</RelativeLayout>
[/HIGH]

</LinearLayout>

[/HIGH]

This is my adpater java file:

[HIGH] 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;
Gallery 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 = (Gallery) convertView.findViewById(R.id.model);
holder.txtBrand = (TextView) convertView.findViewById(R.id.brand);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
listViewAdapter = new ListAdapter(context, laptops);

Laptop laptop = (Laptop) getItem(position);
holder.txtModel.setAdapter(listViewAdapter);
holder.txtBrand.setText(laptop.getBrand());

return convertView;
}
}
[/HIGH]

This is my ListAdapter.java class:
[HIGH]public class ListAdapter extends ArrayAdapter<Laptop> {
Activity context;
List<Laptop> laptops;

public ListAdapter(Activity context, List<Laptop> laptops) {
super(context, R.layout.listrow, laptops);
this.context = context;
this.laptops = laptops;
}

/*private view holder class*/
private class ViewHolder {
ImageView imageView;
TextView 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.listrow, null);
holder = new ViewHolder();
holder.txtModel = (TextView) convertView.findViewById(R.id.articletitle);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}

Laptop laptop = (Laptop) getItem(position);
holder.txtModel.setText(laptop.getModel());
return convertView;
}
[/HIGH]

SAXHandler.java:
[HIGH]
public class SAXXMLHandler extends DefaultHandler {
private List<Laptop> laptops;

// private List<Laptop> articles;
public boolean current = false;
public String currentValue = null;
boolean isArticle,isThumbURL;
// to maintain context
private Laptop laptop;
private Laptop article;
private Laptop image;
public SAXXMLHandler() {
laptops = new ArrayList<Laptop>();
}

public List<Laptop> getLaptops() {
return laptops;
}


// Event Handlers
public void startElement(String uri, String localName, String qName,
Attributes attributes) throws SAXException {
// reset
current = true;
if (localName.equals("Categories")) {
// create a new instance of Laptop
laptop = new Laptop();
laptops = new ArrayList<Laptop>();
}

else if (localName.equals("Category")) {
// create a new instance of Laptop
laptop = new Laptop();
laptop.setBrand(attributes.getValue("name"));

}
else if (localName.equals("Articles")) {
// create a new instance of Laptop
article = new Laptop();
isArticle = true;

}

else if (localName.equals("article")) {

// create a new instance of Laptop
article = new Laptop();
article.setModel(attributes.getValue("title"));

}

}

public void characters(char[] ch, int start, int length)
throws SAXException {
if(current)
{
currentValue = new String(ch, start, length);
current=false;
}
}

public void endElement(String uri, String localName, String qName)
throws SAXException {
current = false;
if (localName.equals("Categories")) {
// add it to the list
// laptops.add(laptop);

}

else if (localName.equals("Category")) {
// add it to the list
laptops.add(laptop);


}
else if (localName.equals("Articles")) {
// add it to the list
isArticle = false;


}
else if (localName.equals("article")) {
laptops.add(article);


}

}
}
[/HIGH]
