解析Android中嵌套的JSON对象 [英] Parsing nested JSON object in Android

问题描述

我试图解析一个JSON对象，其中有一部分是这样的：

I'm trying to parse a JSON object, part of which looks like this:

{
"offer":{
    "category":"Salon",
    "description":"Use this offer now to enjoy this great Salon at a 20% discount. ",
    "discount":"20",
    "expiration":"2011-04-08T02:30:00Z",
    "published":"2011-04-07T12:00:33Z",
    "rescinded_at":null,
    "title":"20% off at Jun Hair Salon",
    "valid_from":"2011-04-07T12:00:31Z",
    "valid_to":"2011-04-08T02:00:00Z",
    "id":"JUN_HAIR_1302177631",
    "business":{
        "name":"Jun Hair Salon",
        "phone":"2126192989",
        "address":{
            "address_1":"12 Mott St",
            "address_2":null,
            "city":"New York",
            "cross_streets":"Chatham Sq & Worth St",
            "state":"NY",
            "zip":"10013"
        }
    },

等等....

And so on....

到目前为止，我能够解析非常简单，通过这样做有点事：

So far, I'm able to parse very simply, by doing this kinda thing:

JSONObject jObject = new JSONObject(content);
JSONObject offerObject = jObject.getJSONObject("offer");
String attributeId = offerObject.getString("category");
System.out.println(attributeId);

String attributeValue = offerObject.getString("description");
System.out.println(attributeValue);

String titleValue = offerObject.getString("title");
System.out.println(titleValue);`

但是当我尝试它的名字：它不会工作。

But when I try it for 'name:' it won't work.

我已经试过：

JSONObject businessObject = jObject.getJSONObject("business");
String nameValue = businesObject.getString("name");
System.out.println(nameValue);

当我尝试了，我得到的JSONObject [商家]没有找到。

When I try that, I get "JSONObject [business] not found."

当我尝试：

String nameValue = offerObject.getString("name");
System.out.println(nameValue);`

我得到，正如所料，JSONObject的[名]未找到。

I get, as expected, "JSONObject [name] not found".

我在做什么错在这里？我失去了一些东西基本....

What am I doing wrong here? I'm missing something basic....

推荐答案

好吧，我是个白痴。这个工程。

Ok, I'm an idiot. This works.

JSONObject businessObject = offerObject.getJSONObject("business");
String nameValue = businessObject.getString("name");
System.out.println(nameValue);

如果我只觉得两秒钟，然后再发布... JEES！

If I would only think for two seconds before posting... Jees!
