Answer 1

String json = "";
try {
JSONArray arr = new JSONArray(json);
for (int i=0; i<arr.length(); i++) {
JSONObject obj = arr.getJSONObject(i);
String secondId = obj.getString("secondId");
String lessonpId = obj.getString("lessonpId");
String secondTitle = obj.getString("secondTitle");
JSONArray recordArr = obj.getJSONArray("record");
for (int j=0; j<recordArr.length(); j++) {
JSONObject recordObj = recordArr.getJSONObject(j);
// String secondId2 = recordObj.getString("secondId");
String threeTitle = recordObj.getString("threeTitle");
String threeId = recordObj.getString("threeId");
}
}
} catch (JSONException e) {
e.printStackTrace();
}
