Android:Java:JSON解析而不使用GSON或jackson

我是JSON新手，我从服务器获取了以下JSON字符串，希望使用每个对象项并遍历此JSON

无需使用GSON或Jackson库。视频Id和拇指对我来说是最优先的

     {'videos': [ { "video":                                                        {"duration":"2:51","views":36824,"video_id":"41141","rating":"4.25","ratings":"51","title":"                            video1","url":"http:\/\/www.xyz.com\/41141","default_thumb":"http:\/\/img02.xyz.com\/_thumbs   \/0000041\/0041141\/0041141_015m.jpg","thumb":"http:\/\/img02.xyz.com\/_thumbs\/0000041\/004      1141\/0041141_015m.jpg","publish_date":"2014-03-27 05:38:01"}},
  {"video":{"duration":"2:51","views":36825,"video_id":"4141","rating":"4.25","ratings":"51","title":"video2","url":"http:\/\/www.xyz.com\/4141","default_thumb":"http:\/\/img03.xyz.com\/_thumbs\/0000041\/0041141\/0041141_015m.jpg","thumb":"http:\/\/img03.xyz.com\/_thumbs\/0000041\/0041141\/0041141_015m.jpg","publish_date":"2014-03-27 05:38:01"}},
{ "video":{"duration":"2:51","views":36225,"video_id":"41412","rating":"4.25","ratings":"51","title":"video3","url":"http:\/\/www.xyz.com\/41412","default_thumb":"http:\/\/img04.xyz.com\/_thumbs\/0000041\/0041141\/0041141_015m.jpg","thumb":"http:\/\/img04.xyz.com\/_thumbs\/0000041\/004 1141\/0041141_016m.jpg","publish_date":"2014-03-27 05:38:01"}}
}}],"count":279369}

JSONArray videojarray=jobj.getJSONArray（“视频”）；
JSONObject videoJObject=null；
对于（int j=0；j您的JSON无效，请在JSON开头的视频中将单引号
“
更改为双引号
”
，并在计数前删除两个右括号
}
。然后尝试解析您的有效JSON

更正后的JSON如下所示：

{
    "videos": [
        {
            "video": {
                "duration": "2:51",

            }
        }
    ],
    "count": 279369
} 

试试这个

JSONObject jobj = new JSONObject(response);
JSONArray videosjarray = jobj.getJSONArray("videos");
for(int j=0;j < videosjarray.length();j++){
  JSONObject videosJObject = videosjarray.getJSONObject(j);
  JSONObject video = videosJObject.getJSONObject("video");
  String videoid = video.getString("video_id");
  String thumb = video.getString("thumb");
}

JSONObject jobj=新的JSONObject（响应）；
JSONArray videosjaray=jobj.getJSONArray（“视频”）；
对于（int j=0；j

您的JSON无效，请从此处进行检查，如
您是否已经自己搜索了？我想您错过了
视频
数组中的
对象。请参阅我的ans
JSONObject jobj = new JSONObject(response);
JSONArray videosjarray = jobj.getJSONArray("videos");
for(int j=0;j < videosjarray.length();j++){
  JSONObject videosJObject = videosjarray.getJSONObject(j);
  JSONObject video = videosJObject.getJSONObject("video");
  String videoid = video.getString("video_id");
  String thumb = video.getString("thumb");
}
