Npe While Using Hashmap To Populate Listview
I am creating an android app for a restaurant that lets the waiters take the customers orders. I am using a extended list view to show the menu and have used a hashmap to populate
Solution 1:
One problem could be that you're initializing the adapter after you set it and all items in it are null
Exp_list.setAdapter(adapter);
adapter = newFoodMenuAdapter(this, Food_menu, Food_list);
This might solve the problem:
adapter = newFoodMenuAdapter(this, Food_menu, Food_list);
Exp_list.setAdapter(adapter);
