How to set ArrayAdapter to Listview - Android

How to set ArrayAdapter to Listview - Android

I have a class that extends ArrayAdapter . I can not set the ListAdapter
to my ListView because I don't know what the code should be when I try to
create the ListAdapter. Here is my current code.
class Item {
String username;
String number;
String content;
}
class ListAdapter extends ArrayAdapter<Item> {
public ListAdapter(Context context, int textViewResourceId) {
super(context, textViewResourceId);
// TODO Auto-generated constructor stub
}
private List<Item> items;
public ListAdapter(Context context, int resource,
List<Item> items) {
super(context, resource, items);
this.items = items;
}
@Override
public View getView(int position, View convertView,
ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi;
vi = LayoutInflater.from(getContext());
v = vi.inflate(R.layout.list_item, null);
}
Item p = items.get(position);
if (p != null) {
TextView tt = (TextView) v.findViewById(R.id.id);
TextView tt1 = (TextView)
v.findViewById(R.id.categoryId);
TextView tt3 = (TextView)
v.findViewById(R.id.description);
if (tt != null) {
tt.setText(p.getId());
}
if (tt1 != null) {
tt1.setText(p.getCategory().getId());
}
if (tt3 != null) {
tt3.setText(p.getDescription());
}
}
return v;
}
}
Here is where I get the problem, trying to declare the ListAdapter
ListView yourListView = (ListView)
findViewById(android.R.id.list);
// Here is the problem
ListAdapter customAdapter = new ListAdapter(this,
R.layout.list_item, List<Item> //I get an error right
here);
yourListView .setAdapter(customAdapter);
