推荐答案

正如在评论你的问题，看来你的服务器返回的XML而不是JSON。你可以只输出的结果很容易地证实了这一点：

As pointed out in the comments to your question, it appears that your server is returning XML rather than JSON. You can easily confirm this by just outputting result:

}catch(JSONException e){
    Log.e("log_tag", "Error parsing data "+e.toString());
    Log.e("log_tag", "Failed data was:\n" + result);
}

如果是XML，它几乎可以肯定一定是，那么您可能需要获取服务器输出的JSON或者您需要解析它送你的XML。

If it's XML, which it almost certainly must be, then you either need to get the server to output JSON or you need to parse the XML that it's sending you.
