Android 解析 嵌套的JsonArray 这个具体该怎么解析呢？

String json = "";
try {
JSONArray arr = new JSONArray(json);
for (int i=0; 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 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();
}

完全可以，用activityGroup

用 fastjson
