Please try this

try {
                ArrayList<String> topicsList = new ArrayList<>();
                JSONObject jsonObject = new JSONObject(resultJSON);
                JSONArray result = jsonObject.getJSONArray("results");
                for(int i=0;i<result.length();i++) {
                    JSONObject jsonObject1 = result.getJSONObject(i);
                    JSONArray topics = jsonObject1.getJSONArray("topics");
                    for(int j=0;j<topics.length();j++) {
                        JSONObject jsonObject11 = topics.getJSONObject(j);
                        topicsList.add(jsonObject11.getString("topic_code"));
                    }
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
