    String[] result = new String[cursor.getCount()];
    if (cursor.moveToFirst())
      do { 
        // Extract the name.
        String name = cursor.getString(nameIdx);
        // Extract the phone number.
        String phone = cursor.getString(phoneIdx);
        result[cursor.getPosition()] = name + "-" +" "+  phone; …
