android froyo: how do I add a database driven list to the ListActivity view

Question

I need to be able to use an external XML file in place of the string below. How do I go about adding that in?

package com.HelloListView;

import android.app.Activity; import android.os.Bundle; import android.app.ListActivity; import android.view.View; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.Toast;

public class HelloListView extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final String[] COUNTRIES = new String[] { "Afghanistan", "Albania", "Algeria", "American Samoa", "Andorra", "Angola", "Anguilla", "Antarctica", "Antigua and Barbuda", "Argentina", "Armenia", "Aruba", "Australia" }; setListAdapter(new ArrayAdapter(this, R.layout.list_item, COUNTRIES));

}

}
