{
  "status": "success",

java代码

try {
                JSONObject res = new JSONObject(response);

                if (res.getString("status").equalsIgnoreCase("success")) {
                    JSONArray TQMData = res.getJSONArray("data");
                    for (int i = 0; i < TQMData.length(); i++) {
                        JSONObject obj = TQMData.getJSONObject(i);
                        stepsList.add(new TQMSavedDataModel(obj.getString("tangible_benefits"),
                                obj.getString("intangible_benefits"),
                                obj.getString("total_annual_savings"),
                                (List<RootCauseIdentificationModel>) obj.getJSONObject("root_cause_identification")
                        ));
                    }
                }
            } catch (JSONException e) {
                e.printStackTrace();
                dialog.dismiss();
                Toast.makeText(getActivity(), "Something went wrong, please try again.", Toast.LENGTH_SHORT).show();
                getActivity().finish();
            }

Answer 1

您得到的响应是JSONObject而不是JSONArray。

Answer 2

首先，您应该将data作为JsonObject获取然后，从该对象中，您可以检索所需的数组：）

JSONObject obj = TQMData.getJSONObject("data");
JSONArray arrayData = obj.getJSONArray("root_cause_identification");

快乐编码！
