安卓解析json数据

Json数据: [{"code":"110000","sheng":"11","di":"00","xian":"00","name":"北京市","level":1}, {"code":"659004","sheng":"65","di":"90","xian":"04","name":"五家渠市","level":3}, {"code":"710000","sheng":"71","di":"00","xian":"00","name":"台湾省","level":1}, {"code":"810000","sheng":"81","di":"00","xian":"00","name":"香港特别行政区","level":1}, {"code":"820000","sheng":"82","di":"00","xian":"00","name":"澳门特别行政区","level":1}]

 

json_btn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { String s = getString(); Log.d("txt",s); List<City> list = new ArrayList<City>(); try { JSONArray obj = new JSONArray(s); for(int i=0;i<obj.length();i++){ JSONObject jsonobj = (JSONObject)obj.get(i); City city = new City(); city.setCode(jsonobj.getString("code")); city.setSheng(jsonobj.optString("sheng")); city.setDi(jsonobj.optString("di")); city.setXian(jsonobj.optString("xian")); city.setName(jsonobj.optString("name")); city.setLevel(jsonobj.optInt("level")); Log.d("txt",city.toString()); textView.append(city.toString()); } } catch (JSONException e) { e.printStackTrace(); } } });

先获取JSON数组，在解析JsonObject。 

city的代码我就不放了  就是一个bean类(实体类) ,复制json字符串  上Androidstuodio找GsonFormat插件直接转就OK,
