Adnroid解析Json数组DEMO实例


在线生成JAVA实体类工具


需要用到的Json解析库Gson请自行解决


下面我们来看下具体用法

1、使用Android中的JSONObject和JSONArray解析json数据


view source
print?
01String strJson = "{\"UrlName\":[{\"name\":\"jsons.cn\",\"age\":2}, {\"name\":\"Json工具\",\"age\":2}]}";
02        try {
03            JSONObject jo = new JSONObject(strJson);
04            JSONArray jsonArray = (JSONArray) jo.get("UrlName");
05            for (int i = 0; i < jsonArray.length();   i) {
06                JSONObject o = (JSONObject) jsonArray.get(i);
07                System.out.println("name:"   o.getString("name")   ","   "age:"
08                          o.getInt("age"));
09            }
10        } catch (JSONException e) {
11            e.printStackTrace();
12        }
2、使用Gson中的JsonReader解析json数据



view source
print?
01try {
02            String string = "{\"Root\":1, \"UrlName\":[{\"name\":\"Jsons.cn\", \"age\":2},{\"name\":\"Json解析\", \"age\":2}]}";
03            StringReader sr = new StringReader(string);
04            JsonReader jr = new JsonReader(sr);
05            jr.beginObject();
06            if (jr.nextName().equals("Root")) {
07                System.out.println("最高级别: "   jr.nextString());
08                if (jr.nextName().equals("UrlName")) {
09                    jr.beginArray();
10                    while (jr.hasNext()) {
11                        jr.beginObject();
12                        if (jr.nextName().equals("name"))
13                            System.out.print("姓名："   jr.nextString());
14                        if (jr.nextName().equals("age")) {
15                            System.out.println(" , 年龄："   jr.nextInt());
16                        }
17                        jr.endObject();
18                    }
19                    jr.endArray();
20                }
21            }
22            jr.endObject();
23        } catch (FileNotFoundException e) {
24            e.printStackTrace();
25        }
