java - 如何从 Android 中的 JSON 解析中深入提取对象/数组

Question

JSON 代码:http://headytunes.co/?json=1

我正在尝试提取作者姓名，但只重复 JSON 列表中的第一作者。我也在尝试从这个 JSON 中提取缩略图和多个类别，但我无法正确提取图像或标签。

     HttpEntity entity = response.getEntity();
                String data = EntityUtils.toString(entity);
                Actors actor = new Actors();
                JSONObject jsono = new JSONObject(data);
                JSONArray jarray = jsono.getJSONArray("posts");
                JSONObject jsonoTwo =jsono.getJSONArray("posts").getJSONObject(0).getJSONObject("author");

                for (int i = 0; i < jarray.length(); i++) {
                    JSONObject object = jarray.getJSONObject(i);

                    actor = new Actors();

                    actor.setName(object.getString("title"));
                    actor.setDescription(object.getString("excerpt"));
                    actor.setDate(object.getString("date"));
                    actor.setAuthor(jsonoTwo.getString("name"));
                    //.setTags(jsonoThree.getString("title"));
                    //actor.setImage(images.getString("url"));

                    songList.add(actor);

我希望它没有任何错别字:

for (int i = 0; i < jarray.length(); i++) {
                        JSONObject object = jarray.getJSONObject(i);

                        actor = new Actors();

                        actor.setName(object.getString("title"));
                        actor.setDescription(object.getString("excerpt"));
                        actor.setDate(object.getString("date"));
                        actor.setAuthor(object.getString("name"));

                        JSONArray tags = object.getJSONArray("tag");
                        for (int j = 0; j < tags.length(); j++) {
                          // you can access each tag in this section 
                        }

                        JSONArray attachment = object.getJSONArray("attachment");
                        for (int k = 0; k < tags.length(); k++) {
                          // you can access inside attachment 
                        JSONObject insideAttachmentObj = attachment.getJSONObject(k);
                        insideAttachmentObj.getJSONObject("images").getJSONObject("thumbnail");
                        //or for accessing url :insideAttachmentObj.getJSONObject("images").getJSONObject("thumbnail").getString("url");
                        }



                        songList.add(actor);
