编辑JSON字段

问题描述

我有一个JSON从服务器来如下

i have an json coming from server as below

   {
    "XXXX": {
        "type": "RSS",
        "value": ""
    },
    "YYYY": {
        "type": "String",
        "value": ""
    },
    "ZZZZ": {
        "type": "String",
        "value": ""
    }
}

现在我需要在所有的XXXX，YYYY和ZZZZ的字段中添加SRING值

now i need to add the Sring value in field of all XXXX ,YYYY,and ZZZZ

使用eclipse IM，我需要改变XXXX价值和YYYY ZZZZ和的价值，我需要添加字段

im using eclipse and i need to change the value of "value" in XXXX and YYYY and ZZZZ and i need to add the field

{
    "MMMM": {
        "type": "Image",
        "value": "a7e8bec0-87ed-11e2-aa2e-52540025ab96_2_1362746556"
    }
}

在ZZZZ ..please让我知道该怎么做。

推荐答案

试试这个

String jsonstring="{
    "XXXX": {
        "type": "RSS",
        "value": ""
    },
    "YYYY": {
        "type": "String",
        "value": ""
    },
    "ZZZZ": {
        "type": "String",
        "value": ""
    }
}";

JSONObject object=new JSONObject(jsonstring);
JSONObject childobject=object.getJSONObject("XXXX");

JSONObject modifiedjson=new JSONObject();
modifiedjson.put("type",childobject.get("type"));
modifiedjson.put("value","newvalue");  // Add new value of XXXX here

//

JSONObject mmjson=new JSONObject();
mmjson.put("type","image");
mmjson.put("value","a7e8bec0-87ed-11e2-aa2e-52540025ab96_2_1362746556");  // Add new value of MMM here

JSONObject newjson=new JSONObject();
newjson.put("MMMM",mmjson.toString());
newjson.put("XXXX",modifiedjson.toString());
newjson.put("YYYY",object.get("YYYY"));
newjson.put("ZZZZ",object.get("ZZZZ"));
