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;
}
