如何在输出中的两个数组中提取java中的jsonarray

Question

如何从以下JSON对象中检索ids数组。

{"bets":[{"bet":[{"gid":"10","Result":null}]},{"bet":[{"gid":"7","Result":null}]},{"bet":[{"gid":"3","Result":null},{"gid":"6","Result":"2"}]},{"bet":[{"gid":"6","Result":"2"},{"gid":"4","Result":"1"}]},{"bet":[{"gid":"6","Result":"2"},{"gid":"4","Result":"1"}]}]}{"ids":["9c9nogs6of","ank4kt3gqo","jfgrt91nk4","a8qmoq7v4q","8mov5ita1t"]}

我试过

     allids = jObj.getJSONArray("ids");

哪个应该有效，因为它适用于jObj.getJSONArray("bets");但是我在logcat E/Buffer Error﹕ Error converting result org.json.JSONException: No value for ids

中收到此错误

PHP文件

  <?php
        // get tag
   $param= $_POST['param'];
   $bet = explode("//",$param);
   $allbetslength = count($bet);
   $ultresponse["bets"] = array();
   $idresponse["ids"] = array();
  for ($x = 0; $x < $allbetslength; $x++) {
   $indid = substr($bet[$x],0,10);
  array_push($idresponse["ids"], $indid);
   $bet[$x] = substr($bet[$x],10);
  

   $id = explode(",",$bet[$x]);
   $arrlength = count($id);
   //  include db handler
         require_once 'include/Check_Bets.php';


        $db = new Check_Bets();
        $response["bet"] = array();


   for($y = 0; $y < $arrlength; $y++) {

        $result= $db->checkuserbets($id[$y]);
        array_push($response["bet"], $result);
        }
   array_push($ultresponse["bets"], $response);
   array_push($ultresponse["bets"], $idresponse["ids"]);
       }
        echo json_encode($ultresponse);

    ?>
