如何解析 Facebook 数据 [英] How to Parse Facebook Data

问题描述

我在正确解析 Facebook 数据时遇到了一些问题.

I am having a few problems getting Facebook data to parse properly.

我正在努力实现应用程序的一部分，以允许用户在应用程序中选择和使用他们自己的 facebook 照片之一.我已经让 facebook 登录/注销代码正常工作，我目前正在获取令牌(一旦登录)以收集用户相册信息.权限集也运行良好，但是我现在坚持尝试正确解析 JSON 信息.这是我需要解析的信息的示例片段:

I am working on implementing part of an application to allow a user to select and use one of their own facebook photos within the app. I have gotten the facebook login/logout code working and I am currently getting the token (once logged in) in order to gather the users Album information. The permission set is also working nicely, however I am now stuck at trying to get the JSON information to parse correctly. Here is a sample snippet of the information I need to parse:

 "data": [
  {
     "id": "3486732467234",
     "from": {
        "name": "Persons Name",
        "id": "Persons ID"
     },
     "name": "Vacation",
     "location": "City",
     "link": "https://www.facebook.com/album.php?fbid=434235&id=324343&aid=2430",
     "cover_photo": "3489234432",
     "privacy": "everyone",
     "count": 60,
     "type": "normal",
     "created_time": "2007-06-03T23:01:16+0000",
     "updated_time": "2011-03-18T19:46:43+0000",
     "can_upload": true
  },
  {
     "id": "4043544665",
     "from": {
        "name": "Persons Name",
        "id": "Persons ID"
     },
     "name": "Vacation 2",
     "location": "City",
     "link": "https://www.facebook.com/album.php?fbid=4043434665&id=508154335&aid=2555",
     "cover_photo": "5434543",
     "privacy": "everyone",
     "count": 60,
     "type": "normal",
     "created_time": "2007-06-03T22:53:03+0000",
     "updated_time": "2011-03-18T19:45:55+0000",
     "can_upload": true
  }],
...more paging JSON information ...}}

我需要能够提取相册信息，以便在列表中显示相册名称(并在另一个查询中使用 ID).一旦我可以显示相册，我就会使用这些 ID 执行另一个查询以从该相册中获取照片.我也可以再次取回该信息，我只是不确定如何正确解析它.

I need to be able to pull the album information in order to display the photo album names in a list (and use the ID in another query). Once I can get the albums to show, I would then use those IDs to perform another query to get the photos from that album. Again I can also get that information back, I am just not sure how to properly parse it.

如果有人能够将其解析为列表视图，任何有用的提示将不胜感激.

Any useful tips that someone might have in being able to parse this into a listview would be greatly appreciated.

我需要从第一个列表中提取第一个 ID 和专辑名称(id":3486732467234"和name":Vacation")

I need to target pulling the first ID and the Album name ("id": "3486732467234" and "name": "Vacation" from the first listing)

推荐答案

为什么不试试 json 类...

why don't you try with the json classes...

像这样:

        jsonObject = new JSONObject(your_data);
        jArray = jsonObject.getJSONArray("data");

        for(int i =0;i<jArray.length();i++){

            String name= jArray.getJSONObject(i).getString("name");
            String location= jArray.getJSONObject(i).getString("location");
