Question

如何从下面的字符串中获取值fan_count，第一 message和created_time。

我已尝试过下面的代码，但显然不起作用：

facebook_Fan_Count = queryResults.get(0).getString("fan_count");
facebook_post = queryResults.get(0).getString("message");

字符串：

{
  "data": [
    {
      "name": "count",
      "fql_result_set": [
        {
          "fan_count": 732
        }
      ]
    },
    {
      "name": "messages",
      "fql_result_set": [
        {
          "message": "Weekly class with Sheikh Hassan on TILAWA \n(implementing tajweed)\n\nEvery Friday after Maghreb\nCommencing 6th December at Daar Ibn Abbas.",
          "timeline_visibility": "normal",
          "created_time": 1386230874
        },
        {
          "message": "SMS SERVICE:\n\nTo keep up to date with events and prayer times at Daar Ibn Abbas please inbox us your name and number.\n\nJazackAllah khier",
          "timeline_visibility": "starred",
          "created_time": 1386022521
        }
      ]
    }
  ]
}

要提取fan_count，1st message和created_time的值，你可以进行Json解析

JSONArray ar = (JSONArray) jsonObject.get("data");

您可以遍历此数据并获取第一条消息

从第一次迭代中你可以获得fan_count

jsonObject = (JSONObject) ar.get(0);

fan_count 不是字符串，类型为long。

所以你需要做这样的事情

long count = (Long) jsonObject.get("fan_count");

从第二次迭代中，您可以获得消息并创建日期

jsonObject = (JSONObject) ar.get(1);
String message = (String) obj1.get("message");
long dt = (Long) obj1.get("created_time");

从facebook jql中提取json值
