Well, the question is very clear, I need to know which method of the adapter is what determines how many elements a listview will have.

When I speak of adapter, I mean baseadapter, to this:

@Override
public int getCount() {
    return null ;
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {


    return convertView;
}

In the case of BaseAdapter the method is getCount ()

   class myAdapter extends BaseAdapter {

        public int getCount() {
            //Define el numero de elementos
            return listaElement.size();
        }

    }

getCount () determines how many elements are in the set of data represented by this adapter.

You can see it in the class SimpleAdapter which is a subclass.
