Custom adapter does not called getVIew - adapter

Question

Here is the code of my custom adapter... it doesn't call my get view... returns only white blank page without nothing. I don't know what is the problem. Does anybody can help. Thanks a lot previously!
public class ProductShopsAdapter extends ArrayAdapter<ProductShop> {
private Context cntx;
private ArrayList<ProductShop> shopValues;
ProductShopsHolder holder = null;
public ProductShopsAdapter(Context context, int textViewResourceId, ArrayList<ProductShop> stringValues) {
super(context,textViewResourceId);
shopValues = stringValues;
cntx = context;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
holder = new ProductShopsHolder();
LayoutInflater layoutInflater = (LayoutInflater)cntx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.shops_list, null);
//Holder Elements initialization
holder.setShopName((TextView)convertView.findViewById(R.id.shop_name));
holder.setPrice((TextView)convertView.findViewById(R.id.shop_part_price));
convertView.setTag(holder);
} else {
holder = (ProductShopsHolder) convertView.getTag();
}
holder.getShopName().setText(getItem(position).getShopName());
holder.getPrice().setText(getItem(position).getPrice());
return convertView;
}
}
and here is my XML
<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ProductShopsActivity" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/footer"
android:padding="0dp" >
</ListView>
<include

android:layout_alignLeft="#android:id/list"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
layout="#layout/footer_menu" />
</RelativeLayout>

You don't need ArrayList inside your ArrayAdapter - ArrayAdapter can store items itself. And that's why getView() doesn't get called - default implementation of getCount() returns the number of items in ArrayAdapter itself. If you keep your items in your own ArrayList, at least override getCount() to return shopValues.getCount(). Otherwise it is always 0 and the ListView to which your adapter is bound doesn't even know there are any items to dsplay at all.
