Android读取json配置

发表于   |     |   阅读次数

工作的新需求，需要加过滤，但是过滤的字段没有服务，只能像服务端一样写本地配置化。。。orz
把配置写成json格式放在assets下面。

1.构造json放在assets下面，如图

            int len = array.length();
            Map<String, String> map;
            for (int i = 0; i < len; i++) {
                JSONObject object = array.getJSONObject(i);
                map = new HashMap<String, String>();
                map.put("Code", object.getString("Code"));
                map.put("Name", object.getString("Name"));
                data.add(map);
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return data;
    }
}

3.在activity里面调用代码：
