BaseAdapter notifyDatasetChanged() called but getView() is never called

Question

I have a custom adapter that visualize each row in the list of Orders.

public class OrderRowAdapter extends BaseAdapter implements OnClickListener {
    Ord         


        

Answer 1

To change the content of your ListView, you must keep using the same reference to the List. Here you're creating another list and assigning it to the items_ variable (which does not contain the list itself, it's just a place to store a reference to a List), but your View still has a reference to the old list.

Instead of items_ = new_order_list this should work :

items_.clear();
items_.addAll(new_order_list);

EDIT :

To explain it better, try to create a new variable named old_items :

public void setNewOrderList(List new_order_list)
{
    Log.d(TAG, "New Order List available. Num items = " + new_order_list.size());

    List old_items = items_; // store the reference to the old list
    items_ = new_order_list;

    Log.d(TAG, "items_.size() = " + items_.size());
    Log.d(TAG, "old_items.size() = " + old_items.size()); // The old list still exists, and it's the one used by your ListView

    notifyDataSetChanged();
}
