JSONobject(index)

如何解决JSONobject(index)

我有这个数组

 [{"userId":1,"id":1,"title":"delectus aut autem","completed":false},{"userId":1,"id":2,"title":"quis ut nam faciliset officiqui","id":3,"title":"fugiat veniam minus","id":4,"title":"et porro tempora","completed":true},"id":5,"title":"laboriosam mkjakai","completed":false}]

我正在使用这个命令

 Log.d("TAG","onResponse: "+response.getJSONObject(0));

我期待这个

 {"userId":1,"completed":false}

但不考虑整数索引。我得到这个

  [{"userId":1,"title":"quis ut namfacilisetofficiqui","completed":false}]

我想了几个小时。任何帮助表示赞赏。谢谢。

解决方法

try this:

JSONObject obj = new JSONObject(" .... ");
String pageName = obj.getJSONObject("pageInfo").getString("pageName");

JSONArray arr = obj.getJSONArray("posts");
for (int i = 0; i < arr.length(); i++)
{
  String post_id = arr.getJSONObject(i).getString("post_id");
  ......
}
