}
});
// TextView extratxt = (TextView) rowView.findViewById(R.id.textView1);

imageView.setImageResource(imgid[position]);
txtprice.setText(itemprice[position]);
// extratxt.setText("Description "+itemname[position]);
return rowView;
}
}
}
}
这样做:-
public class All_Products extends ListFragment {
//Watever variables u are using
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
//vies defining here
return rootView;
}
//CHANGE HERE
class CustomListAdapter extends ArrayAdapter<String> {
}
}
