java - 如何解析此 JSON 对象以获取可以使用的配方对象列表？

Question

所以我对 Java 非常陌生，需要帮助解析 JSON 响应。我已经有了我用来这样做的方法，但需要帮助找出我到底做错了什么。

我正在使用 API 从网站检索食谱。我正在尝试获取食谱列表(我假设在这种情况下为“点击”？)，然后我可以将其显示给用户。

显然我需要食谱名称(在本例中为“标签”)和其他信息。谁能帮我吗？

这是我收到的响应 api 响应:

这是我目前用来解析 JSON 对象的方法:

public void onResponse(Call call, Response response) throws IOException {

                    if (response.isSuccessful()) {
                        final String myResponse = response.body().string();
                        getActivity().runOnUiThread(new Runnable() {
                            private Object Date;

                            @Override
                            public void run() {
                                String jsonData = myResponse;
                                query_result.setText(myResponse);
                                Log.d("response5", myResponse);
                                //JSONObject jsonData1 = new JSONObject(myResponse);
                                JSONObject Jobject = null;
                                try {
                                    Jobject = new JSONObject(jsonData);
                                    Log.d("jobject", Jobject.toString());
                                } catch (JSONException e) {
                                    e.printStackTrace();
                                }

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

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

                                        }
                                        for (int j = 0; j < Jarray.length(); j++){
                                            JSONObject object2 = null;
                                            try {

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

                            }
                        });
                    }
                }
            });

            return null;
        }
    }

注意 {} {} 只是不同的配方...它不适合整个响应

目前，当我尝试在日志中打印变量时，我收到一条消息，指出该变量为空(我用来存储不同食谱/“命中”的变量。
