我的工作

try {

                jobj_trouve_train = new JSONObject(reponse_trouve_train);

                String jsonobj = jobj_trouve_golf.getString("trains");
                //String jsonobj1 = jobj_trouve_golf.getString("train");

                //jobj_trouve_train = new JSONObject(reponse_trouve_train);

                //jsonArray = jobj_trouve_golf.getJSONArray("trains");
                //jsonArray= new JSONArray(jsonobj);

                //System.out.println("jsonArray "+jsonArray);

            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }

Answer 1

试试这个..。

try {

                jobj_trouve_train = new JSONObject(reponse_trouve_train);

                JSONObject jsonobj = jobj_trouve_train.getJSONObject("trains");
                JSONArray jsonobj1 = jsonobj.getJSONArray("train");

          for(int i = 0;i< jsonobj1.length();i++){
                JSONObject jsonj = jsonobj1.getJSONObject(i);

                System.out.println("@id "+jsonj.getString("@id"));
                //   Same for remaining all 
                }

            } catch (JSONException e) {
                // TODO Auto-generated catch block                  

                   e.printStackTrace();
        }

Answer 2

您可以使用谷歌开发的Gson库将Json解析为objects。参考在这里：https://code.google.com/p/google-gson/，并且，示例示例在这里：JSON Parsing with GSON

Answer 3

JSONObject trains = jobj_trouve_train.getJSONObject("trains");
JSONArray trainArray = trains.getJSONArray("train");

JSONObject train1 = trainArray.getJSONObject(0);
...

如果我没有被弄糊涂，也许这张是对的
