如何在JAVA中对JSONArray进行排序

试试这个：

    //I assume that we need to create a JSonArray object from the following string    String jsonArrStr = "[ { "ID": "135", "Name": "Fargo Chan" },{ "ID": "432", "Name": "Aaron Luke" },{ "ID": "252", "Name": "Dilip Singh" }]";    JSonArray jsonArr = new JSonArray(jsonArrStr);    JSonArray sortedJsonArray = new JSonArray();    List<JSONObject> jsonValues = new ArrayList<JSONObject>();    for (int i = 0; i < jsonArr.length(); i++) {        jsonValues.add(jsonArr.getJSonObject(i));    }    Collections.sort( jsonValues, new Comparator<JSONObject>() {        //You can change "Name" with "ID" if you want to sort by ID        private static final String KEY_NAME = "Name";        @Override        public int compare(JSonObject a, JSonObject b) { String valA = new String(); String valB = new String(); try {     valA = (String) a.get(KEY_NAME);     valB = (String) b.get(KEY_NAME); }  catch (JSonException e) {     //do something } return valA.compareTo(valB); //if you want to change the sort order, simply use the following: //return -valA.compareTo(valB);        }    });    for (int i = 0; i < jsonArr.length(); i++) {        sortedJsonArray.put(jsonValues.get(i));    }

排序后的JSONArray现在存储在

sortedJsonArray
