JSON格式字符串解析方法(NEW)

注：菜鸟阶段时曾写过一个json解析方法，硬生生是用各种split方法解析出来的结果，其后不久学到了新知识org.json.JSONObject，方便实用，其实也就是封装好的一个解析方法。多的不说，老规矩，直接贴代码，本例子是含json数组，基础的josn格式数据只需JSONObject就可解出，可以自行敲敲摸索下。

result字符串data为：

{"btss":[["gsm","460-1-7122-42151","114.267075","30.468204","1400"],["gsm","460-0-28707-54076","114.265625","30.466845","1000"],["gsm","460-0-28707-54075","114.274910","30.465084","2000"],["gsm","460-0-28941-35565","114.264503","30.463678","900"],["gsm","460-0-28707-43525","114.277802","30.467346","2000"],["gsm","460-0-28707-43526","114.271317","30.468971","1000"],["gsm","460-0-28707-43524","114.276787","30.467686","1100"],["gsm","460-0-28941-5501","114.276138","30.453548","2200"],["gsm","460-0-28707-11905","114.265739","30.470036","1100"],["gsm","460-0-28973-17742","114.280411","30.466528","2000"]],"error":0,"message":""}

解析方法：

try {JSONObject json = new JSONObject(result);if (json.has("btss")) {JSONArray arr = JSONArray.fromObject(json.get("btss").toString());for (Object o : arr) {JSONArray a = (JSONArray) o;double[] latlng_ = {Double.parseDouble(a.get(2).toString().trim()),Double.parseDouble(a.get(3).toString().trim())};if (latlng_ != null) {addBts_NewMap(a.get(0).toString(), 0, a.get(1).toString(), latlng_[0] + "",latlng_[1] + "", a.get(4).toString());}}}} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}
