解析没有数组的JSON

问题描述：

我需要解析JSON。不幸的是，我无法按照here中描述的通常方法从JSON字符串获取名称和费率。另外，this one不帮助我。解析没有数组的JSON

{"usd": 
    {"code":"USD", 
    "alphaCode":"USD", 
    "numericCode":"840", 
    "name":"U.S. Dollar", 
    "rate":1.0857128644692, 
    "date":"Mon, 21 Dec 2015 12:00:01 GMT"}, 
"gbp": 
    {"code":"GBP", 
    "alphaCode":"GBP", 
    "numericCode":"826", 
    "name":"U.K. Pound Sterling", 
    "rate":0.72830809326194, 
    "date":"Mon, 21 Dec 2015 12:00:01 GMT"}, 
    "cad": 
    {"code":"CAD", 
     "alphaCode":"CAD", 
     "numericCode":"124", 
     "name":"Canadian Dollar", 
     "rate":1.5123600265482, 
     "date":"Mon, 21 Dec 2015 12:00:01 GMT"} 
}

结果：

“美元”， “1.0857128644692”

“加拿大元” “1.5123600265482”

尝试此解决方案

try { 

     JSONObject MainJsonObject = new JSONObject("Your Sting input data"); 

     Iterator keyNames = MainJsonObject.keys(); 

     while (keyNames.hasNext()) { 

      String keyname = (String) keyNames.next(); 

      JSONObject jsonObject = MainJsonObject.getJSONObject(keyname); 

      // parse this this jsonObjectas you required 

     } 
    }catch (Exception e) { 
     e.printStackTrace(); 
    }
