        //contentResolver = getContentResolver(); 



        //Cursor cursor = getContentResolver().query(People.CONTENT_URI, null, null, null, null);     
        Cursor cursor = getContentResolver().query(Data.CONTENT_URI, null, null, null, null);         
        startManagingCursor(cursor);          
        // String[] column = new String[] {Phone.LABEL}; 
        String[] column = new String[] {Phone.LABEL};
        int[] names = new int[] {R.id.contact_name};         
        myAdapter = new SimpleCursorAdapter(this, R.layout.main, cursor, column, names);         
        setListAdapter(myAdapter);     
    } 
}
