Android 如何从JSONobject中的嵌套JSONarray收集数据？

我是Android的新手。我想从Ticketmaster api收集数据并在ListView中显示。我在截击。 api的JSONview

                for (int i = 0; i < response.length(); i++) {
                try {

                    JSONObject obj = response.getJSONObject("_embedded");
                     Iterator iterator = Obj.keys();

                    //while(iterator.hasNext()){
                    String key = (String) iterator.next();
                    JSONObject issue = Obj.getJSONObject(key);
                    JSONArray array = obj.getJSONArray("events");
                    JSONObject obj2 = array.getJSONObject(i);
                    JSONObject obj = response.getJSONObject("_embedded");
                    JSONArray array1 = obj2.getJSONArray("venues");
                    JSONObject obj3 = array1.getJSONObject(0);
                    JSONObject obj4 = obj3.getJSONObject("city");
                    String key1 = (String) iterator.next();
                    JSONObject issue1 = Obj.getJSONObject(key1);
                    Event event = new Event();
                    event.setName(obj2.getString("name"));


                    // adding movie to movies array
                    eventList.add(event);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

                for (int i = 0; i < response.length(); i++) {
                try {

                    JSONObject obj = response.getJSONObject("_embedded");
                     Iterator iterator = Obj.keys();

                    //while(iterator.hasNext()){
                    String key = (String) iterator.next();
                    JSONObject issue = Obj.getJSONObject(key);
                    JSONArray array = obj.getJSONArray("events");
                    JSONObject obj2 = array.getJSONObject(i);
                    JSONObject obj = response.getJSONObject("_embedded");
                    JSONArray array1 = obj2.getJSONArray("venues");
                    JSONObject obj3 = array1.getJSONObject(0);
                    JSONObject obj4 = obj3.getJSONObject("city");
                    String key1 = (String) iterator.next();
                    JSONObject issue1 = Obj.getJSONObject(key1);
                    Event event = new Event();
                    event.setName(obj2.getString("name"));


                    // adding movie to movies array
                    eventList.add(event);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

如图所示，我想显示分类和场馆的数据。但是在模型类中使用时，它没有显示

                for (int i = 0; i < response.length(); i++) {
                try {

                    JSONObject obj = response.getJSONObject("_embedded");
                     Iterator iterator = Obj.keys();

                    //while(iterator.hasNext()){
                    String key = (String) iterator.next();
                    JSONObject issue = Obj.getJSONObject(key);
                    JSONArray array = obj.getJSONArray("events");
                    JSONObject obj2 = array.getJSONObject(i);
                    JSONObject obj = response.getJSONObject("_embedded");
                    JSONArray array1 = obj2.getJSONArray("venues");
                    JSONObject obj3 = array1.getJSONObject(0);
                    JSONObject obj4 = obj3.getJSONObject("city");
                    String key1 = (String) iterator.next();
                    JSONObject issue1 = Obj.getJSONObject(key1);
                    Event event = new Event();
                    event.setName(obj2.getString("name"));


                    // adding movie to movies array
                    eventList.add(event);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

JSONObjectRequest中的代码

                for (int i = 0; i < response.length(); i++) {
                try {

谢谢！！！

请检查这个

JSONObject object = new JSONObject(response.toString());
JSONObject embedded = object.getJSONObject("_embedded");
JSONArray eventsArray = embedded.getJSONArray("events");

for(int i = 0;i<eventsArray.length();i++){
  JSONObject event = eventsArray.getJSONObject(i);
  // Parse data from this event object
}

                for (int i = 0; i < response.length(); i++) {
                try {

                    JSONObject obj = response.getJSONObject("_embedded");
                     Iterator iterator = Obj.keys();

                    //while(iterator.hasNext()){
                    String key = (String) iterator.next();
                    JSONObject issue = Obj.getJSONObject(key);
                    JSONArray array = obj.getJSONArray("events");
                    JSONObject obj2 = array.getJSONObject(i);
                    JSONObject obj = response.getJSONObject("_embedded");
                    JSONArray array1 = obj2.getJSONArray("venues");
                    JSONObject obj3 = array1.getJSONObject(0);
                    JSONObject obj4 = obj3.getJSONObject("city");
                    String key1 = (String) iterator.next();
                    JSONObject issue1 = Obj.getJSONObject(key1);
                    Event event = new Event();
                    event.setName(obj2.getString("name"));


                    // adding movie to movies array
                    eventList.add(event);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

JSONObject object=newjsonobject（response.toString（））；
JSONObject embedded=object.getJSONObject（“_embedded”）；
JSONArray eventsArray=embedded.getJSONArray（“事件”）；
对于（int i=0；i，您可以将json数据转换为pojo模型类。这将帮助您轻松获取值。以下是模型pojo类的示例

请尝试此代码以获取城市

                     Iterator iterator = Obj.keys();

                    JSONObject issue1 = Obj.getJSONObject(key1);
                    Event event = new Event();
                    event.setName(obj2.getString("name"));


                    // adding movie to movies array
                    eventList.add(event);

                } catch (JSONException e) {
                    e.printStackTrace();
                }

for（int i=0；i

另外，我建议使用解析JSON
尝试一下

                for (int i = 0; i < response.length(); i++) {
                try {

                    JSONObject obj = response.getJSONObject("_embedded");
                     Iterator iterator = Obj.keys();

                    //while(iterator.hasNext()){
                    String key = (String) iterator.next();
                    JSONObject issue = Obj.getJSONObject(key);
                    JSONArray array = obj.getJSONArray("events");
                    JSONObject obj2 = array.getJSONObject(i);
                    JSONObject obj = response.getJSONObject("_embedded");
                    JSONArray array1 = obj2.getJSONArray("venues");
                    JSONObject obj3 = array1.getJSONObject(0);
                    JSONObject obj4 = obj3.getJSONObject("city");
                    String key1 = (String) iterator.next();
