Android中的JSONObject和JSONArray解析json数据

今天介绍一下关于json数据解析，我们使用Android中的JSONObject和JSONArray解析json数据,有android开发的朋友可以参考一下。 String strJson = "{"students":[{"name":"Jack","age":12}, {"name":"Vista","age":23}, {"name":"Kaka","age":22}, {"name":"Hony","age":31}]}"; try { JSONObject jo = new JSONObject(strJson); JSONArray jsonArray = (JSONArray) jo.get("students"); for (int i = 0; i JSONObject o = (JSONObject) jsonArray.get(i); System.out.println("name:" + o.getString("name") + "," + "age:" + o.getInt("age")); } } catch (JSONException e) { e.printStackTrace(); } 2.使用gson中的JsonReader解析json数据try { String string = "{"class":1, "students":[{"name":"jack", "age":21},{"name":"kaka", "age":21},{"name":"lucy", "age":21}]}"; StringReader sr = new StringReader(string); JsonReader jr = new JsonReader(sr); jr.beginObject(); if (jr.nextName().contains("class")) { System.out.println("班级: " + jr.nextString()); if (jr.nextName().equals("students")) { jr.beginArray(); while (jr.hasNext()) { jr.beginObject(); if (jr.nextName().equals("name")) System.out.print("姓名：" + jr.nextString()); if (jr.nextName().equals("age")) { System.out.println(" , 年龄：" + jr.nextInt()); } jr.endObject(); } jr.endArray(); } } jr.endObject(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }Json解析库gson: http://code.google.com/p/google-gson/
