ios json解析demo 解析jsonobject

JSONObject解析以对象开始的json

// 解析一个对象
    String str = "{'name':'张三','age':30}";
    // 解析对象数组
    String str2 = "[{'name':'小小','age':10},{'name':'等等','age':5},{'name':'flower','age':3}]";

public void read1(View view) {
        try {
            JSONObject jo = new JSONObject(str);
            String name = jo.getString("name");
            int age = jo.getInt("age");
            Toast.makeText(this, "name:" + name + "age:" + age, 0).show();
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

JSONArray解析以数组开始的json

public void read2(View view) {
        List<String> list = new ArrayList<String>();
        try {
            JSONArray array = new JSONArray(str2);
            for (int i = 0; i < array.length(); i++) {
                JSONObject object = array.getJSONObject(i);
                String name = object.getString("name");
                int age = object.getInt("age");
                list.add("name:" + name + "age:" + age);
            }
            System.out.println(list);
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
