public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    final HashMap<Integer, Personeel> personeelmap = new HashMap<Integer, Personeel>();
    ArrayList<String> list = new ArrayList<String>();
    // Get the data (see above)

    try {
        JSONArray contactinfo = json.getJSONArray("contactlijst");
        // Loop the Array
        for (int i = 0; i < …
