嵌套 JSONArray 记录解析问题 Android

Question

我正在制作一个从服务器接收 JSON 数据的应用程序，用户将从 Spinner 中选择一个值，例如 0、1、2... 等等，基于数字选择 JSON 将返回用户定义的数据像 0,1 这样的索引 .. 我不知道如何在 Android 中解析内部 JSON 数据

json = new JSONObject(JSONParser.Result);
JSONArray jArray = json.getJSONArray("data");
StopElement _stop = new StopElement();
Log.d("JSON Algo Result", json.toString());

if (jArray!=null) {
    for (int i = 0; i < jArray.length(); i++) {
        jsonarray = jArray.getJSONArray(i);
        if (jsonarray != null) {
            for (int j = 0; j < jsonarray.length(); i++){
                if(i==0) {
                    jsonarray = jArray.getJSONArray(j);
                    _stop.setName(jsonarray.getString(0));
                    StopElement.Stop_name_list.add(_stop.getName());
                }
             }
        } else {
            break;
        }
    }
} else {
    return null;
}
