Json解析实例

?

?1. 第一种是对象里面含有数组的json格式如下：

{"audio":{"info":[{"id":1,"icon":"http:\/\/localhost\/test\/mm.jpg","name":"fm930","time":"8:00-12:00","ip":"http:\/\/192.168.3.99\/mp3\/m.mp3"},{"id":1,"icon":"http:\/\/localhost\/test\/mm.png","name":"fm950","time":"8:00-12:00","ip":"http:\/\/192.168.3.99\/mp3\/m.mp3"},{"id":1,"icon":"http:\/\/localhost\/test\/mm.png","name":"fm960","time":"8:00-12:00","ip":"http:\/\/192.168.3.99\/mp3\/m.mp3"}]}}

?

解析如下：

// 获取初始化mms列表public ArrayList<MmsModel> getModelList(String data) {ArrayList<MmsModel> al = new ArrayList<MmsModel>();try {JSONObject jm = new JSONObject(data).getJSONObject("audio");JSONArray jsonArray = jm.getJSONArray("info");for (int i = 0; i < jsonArray.length(); i++) {MmsModel am = new MmsModel();JSONObject jb = (JSONObject) jsonArray.opt(i);am.setId(jb.getString(MmsModel.ID));am.setName(jb.getString(MmsModel.NAME));am.setUrl(jb.getString(MmsModel.URL));al.add(am);}return al;} catch (Exception e) {e.printStackTrace();Log.e("format json:", "false");}return null;}

2. 第二种格式是对象数组的json格式：

[{"id":"1","name":"liu"},{"id":"2","name":"kai"},{"id":"3","name":"lis"},{"id":"4","name":"you"}]

?解析如下：

public static ArrayList<TrafficModel> json4traffic(String data){ArrayList<TrafficModel> al = new ArrayList<TrafficModel>();try {JSONArray jna = new JSONArray(data);for(int i=0; i<jna.length(); i++) {TrafficModel tm = new TrafficModel();JSONObject jb = (JSONObject) jna.opt(i);tm.setId(jb.getString(TrafficModel.ID));tm.setName(jb.getString(TrafficModel.NAME));al.add(tm);//System.out.println("info is ------> : "+jb.getString(TrafficModel.URL));}return al;} catch(Exception e) {e.printStackTrace();}return al;}
