在一種 PHP 中，android 嘗試發送不止一種 json 格式，但只收到一種。我應該怎么辦？Response.Listener<String> responseListener = new Response.Listener<String>() {            @Override            public void onResponse(String response) {                try {                    Log.d("GGGG","onResponse start");                    JSONObject jsonResponse = new JSONObject(response);                    Log.d("GGGG","test" );                    JSONArray jsonArray = jsonResponse.getJSONArray("Search");                    Log.d("GGGG","test1" );                    JSONArray jsonArray2 = jsonResponse.getJSONArray("Favorite");                    Log.d("GGGG","test2" );日志到Logcat.d是輸出到'test1'而不是輸出。我認為我們沒有從“getJSONArray（“收藏夾”）”中獲取值。我應該怎么辦？//--------PHP--------//$userID =$_POST["userId"];   $keyWord = $_POST["keyWord"];    //  $keyWord = "na";    //  $userID ="test";    //??????? ?? ????      $statement ="SELECT * from music where music_title like '%$keyWord%' or music_singer like '%$keyWord%'";    //    echo $statement;    //      exit;      $result = mysqli_query($con,$statement);      $resultArray = array();        while($rows=mysqli_fetch_assoc($result)){          $resultArray[]=$rows;        }      $statement ="SELECT * from favorite_playlist WHERE user_id ='$userID'";      $result = mysqli_query($con,$statement);      $resultArray2 = array();      while($rows=mysqli_fetch_assoc($result)){        $resultArray2[]=$rows;      }      //$response["success"] = true;//success?? ???? true?? ???      header('Content-Type: application/json; charset=utf8');      $json =  json_encode(array("Search"=>$resultArray), JSON_PRETTY_PRINT+JSON_UNESCAPED_UNICODE);      $json2 = json_encode(array("Favorite"=>$resultArray2), JSON_PRETTY_PRINT+JSON_UNESCAPED_UNICODE);      //echo json_encode($resultArray);//JSON???? ??      echo $json;      echo $json2;
