Question

I’m overriding CursorAdapter and I need to get the last item, problem is that CursorAdapter has actually a get() method…but source is a db and it returns a plain object!! (I don’t even know what is it, I’d expect it returning a Cursor object instead…)

Neverthless, how can I make it return an instance of my Wrapper db row class?

Example:
say my db has rows like these:

id|first name| surname

I’d make a class Person from that.

Now I’d like to have a Person get(int i) method from cursor adapter…

This seems like a strange request. I would pass the Cursor itself (or the Cursor returned from CursorAdapter’s getItem()) to a regular method in my Activity instead. But here are the basic steps to create a Person get() method.

Create your Person class:

public class Person {
    long id;
    String firstName;
    String surname;
}

And in your custom CursorAdapter simply use a method like this:

public Person get(int position) {
    Cursor cursor = getCursor();
    Person person;
    if(cursor.moveToPosition(position)) {
        person = new Person();
        person.id = cursor.getLong(cursor.getColumnIndex("_id"));
        person.firstName = cursor.getString(cursor.getColumnIndex("firstName"));
        person.surname = cursor.getString(cursor.getColumnIndex("surname"));
        results.add(person);
    }

    return person;
}
