Notepad example, how does hooking up the notes_row to the notepad_list work

Question

I'm working through the Notepad example, and I'm right at the end of v1. Everything works, I've even added a few small things by playing around with the layout and such. But I just don't understand how R.layout.notepad_list knows to populate itself with the R.layout.notes_row rows. I see how the database cursor is hooked up to populate the rows in this line:

    private void fillData() {
        ....
        SimpleCursorAdapter notesAdapter =
            new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to);
        ....
    }

And I see how the notepad_list is set as the content view in this line:

    public void onCreate(Bundle savedInstanceState) {
        ....
        setContentView(R.layout.notepad_list);
        ....
    }

But how does ListView know to use the rows created by the SimpleCursorAdapter? Is it this line:

    private void fillData() {
        ....
        setListAdapter(notes);
        ....
    }

The help text for setListAdapter is:

void android.app.ListActivity.setListAdapter(ListAdapter adapter)

public void setListAdapter(ListAdapter adapter) Since: API Level 1

Provide the cursor for the list view.

But couldn't I have two ListViews inside notepad_list.xml? How would the code know which one to populate with the data from the cursor?
