解析android中的复杂Json对象

Question

我想从json对象中检索以下字段

  

来自OriginLocation =＆gt;＆gt; CityCode，DepartureDate，DepartureTime

     

来自DestinationLocation =＆gt;＆gt; CityCode，ArrivalTime，ArrivalDate

     

来自票价=＆gt;＆gt; OrigTotalFareAmt

     

来自FlightDetails ==＆gt;＆gt; CabinClassCode，JourneyDuration

使用一个for循环

试试这个。

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 :" + key);
                        System.out.println("Value :" + data.getString(key));
                    }
                } catch (Throwable e) {
                    try {
                        System.out.println("Key :" + key);
                        System.out.println("Value :" + data.getString(key));
                    } catch (Exception ee) {
                    }
                    e.printStackTrace();

                }
            }
        }
    }
