How to update sqlite db from multiple selected items in listview

i want to update my selected item from listview, i can update with a single row, how can i update them if more than one item is selected?

here's my code:

myList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    myList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View view,
                                int position, long id) {
            //TextView textView = (TextView) view.findViewById(R.id.item_version);

            poss = position;
            Cursor cursor = (Cursor) myList.getItemAtPosition
                    (position);
            String id = cursor.getString(cursor.getColumnIndex(DBAdapter.KEY_ROWID));
            String hl = cursor.getString(cursor.getColumnIndex(DBAdapter.KEY_HIGHLIGHT));
            String[] from = new String[]{DBAdapter.KEY_NAME};
            uid = id;




        }
    });

Here's my dbadapter code

 public boolean updateRow(long rowId, String highlight) {
    String where = KEY_ROWID + "=" + rowId;

    ContentValues newValues = new ContentValues();

    newValues.put(KEY_HIGHLIGHT, highlight);

    return db.update(DATABASE_TABLE, newValues, where, null) != 0;
}

Here's my update code:

 int myNum = 1;
            myNum = Integer.parseInt(uid);

               myDB.updateRow(myNum, "Sample updated item to be inserted");
