Answer 1

In your Public UserAdapter function, your super is not passing in the Objects.

It should be:

public UserAdapter(Context context, int resource,List<UserData> objects)
{
    super(context, resource, objects);
    this.context= context;
    this.users_list= objects;
}

and not:

public UserAdapter(Context context, int resource,List<UserData> objects)
{
    super(context, resource);
    this.context= context;
    this.users_list= objects;
}
