Parsing dynamic JSON in Android

Question

I have a json Object is like this:

{
    Yg7R_: {
    fld_invoice: \"Yg7R_\"
    fld_order_id: \"5\"
        fld_orders: {
            4: {
                f         


        

Answer 1

You can do this by one trick. You have to fetch all keys array and corresponding values array of JSONObject. Follow below code.

JSONObject jsonObj = new JSONObject(JsonResponseString);

    JSONArray data1 = jsonObj.getJSONArray("Result");
    JSONObject obj2 = (JSONObject) data1.get(0);

    JSONArray nameArray = obj2.names();
    JSONArray valArray = obj2.toJSONArray(nameArray);

    String status="";
    String gameId="";

    for(int i=0 ; i<valArray.length() ; i++){
        String name = nameArray.getString(i);
        String value = valArray.getString(i);

        if (value.equals("null")) {
            value = "";
        }

        if (name.equalsIgnoreCase(Constants.Key_1)) {
            Log.v(Constants.LOG, + value);

        } else if (name.equalsIgnoreCase(Constants.Key_2)) {
            Log.v(Constants.LOG, + value);

        } else if (name.equalsIgnoreCase(Constants.Key_3)) {
            Log.v(Constants.LOG, + value);

        } 
    }

Answer 2

You don't have any JSON arrays in there. YOu only have JSON objects. You need to use getJSONObject instead. Arrays are surrounded by [] and may have multiple unnamed objects separated by commas. Objects are surrounded by {} and have a single value with a single name.

Try this dynamic json parser

private void parseJson(JSONObject data) {

        if (data != null) {
            Iterator<String> it = data.keys();
            while (it.hasNext()) {
                String key = it.next();
                try {
                    if (data.get(key) instanceof JSONArray) {
                        JSONArray arry = data.getJSONArray(key);
                        int size = arry.length();
                        for (int i = 0; i < size; i++) {
                            parseJson(arry.getJSONObject(i));
                        }
                    } else if (data.get(key) instanceof JSONObject) {
                        parseJson(data.getJSONObject(key));
                    } else {
                        System.out.println(key + ":" + data.getString(key));
                    }
                } catch (Throwable e) {
                    try {
                        System.out.println(key + ":" + data.getString(key));
                    } catch (Exception ee) {
                    }
                    e.printStackTrace();

                }
            }
        }
    }
