refresh my adapter

Question

I have a list of students that I display in an adapter that I create in the class MyCustomAdapter.
Here is the class ManageSection where I call the adapter.

You need to delete record from your list which you pass to your custom dapter adapter(i think studentList is your list) and call notifyDataSetChanged() Method.

Edit :

if (stdel == false) 
{
Toast.makeText(getContext(), "Error deleting student, Please try again",
                    Toast.LENGTH_LONG).show();
}

if(stdel==true)
{
  notifyDataSetChanged();
}

so you mean that studentList(student id ) in class MyCustomAdapter and what about notifyDataSetChanged() where i call it – Maram Watban Dec 18 '12 at 11:16
@MaramWatban Call it after delete record from list. – Chirag Dec 18 '12 at 11:17
@MaramWatban Call notifyDataSetChanged(); after student.remove() in do background method. – Chirag Dec 18 '12 at 11:40
in your code if stdel == true then it not go to in that loop and not call notifydata set changed method. – Chirag Dec 18 '12 at 11:53
