java - Android:Java:不使用 GSON 或 jackson 进行 JSON 解析

Question

我是 JSON 的新手，我有以下从服务器获取的 JSON 字符串，我想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"}}

JSONArray videojarray   =jobj.getJSONArray("videos");
JSONObject videoJObject=null;
for(int j=0;j<videojarray.length();j++){
  videoJObject=videojarray.getJSONObject(j);
  JSONObject  videoJObj=videoJObject.getJSONObject("video");
  String videoid=videoJObj.getString("video_id");
  String thumb=videoJObj.getString("thumb");
}
