안드로이드는 PHP 파일에서 데이터를 읽습니다.

Question

나는 PHP 파일에서 데이터를 읽는 응용 프로그램을 가지고 있습니다. 나는 이미 Google에서 데이터 php를 읽고 TextView로 대체하는 방법을 검색하려고하지만 내 애플리케이션에 코드를 표시하지 않으려 고 시도합니다.

내 PHP 코드 :

<?php 
$serverip = "127.0.0.1"; // Server IP Public 
$portzone = "27780"; // ZoneServer Port 
$portlogin = "10007"; // ZoneServer Port 

$file = file ("E:\SERVER\ZoneServer\SystemSave\ServerDisplay.ini"); 
foreach($file as $line) 
{ 
if(strspn($line, "[") != 1) 
parse_str($line); 
} 

$response["online"] = array(); 
$product["Total Online"] = $UserNum; 
$product["ACC Online"] = $A_Num; 
$product["BCC Online"] = $B_Num; 
$product["CCC Online"] = $C_Num; 
// push single product into final response array 
array_push($response["online"], $product); 
// success 
$response["success"] = 1; 
echo json_encode($response); 

?>

내 텍스트 뷰에 PHP에서 데이터를 교환하는 방법 내 신청?

Answer 1

중첩 된 JSONObject의 값을 '걷기'하지 않고 직접 얻으려고하는 것이 문제입니다.

은 된 JSONObject는 다음과 같습니다 이후 :

{'online': [ 
      {'Total Online': '3',....} 
      ], 
'success': 1 
} 

당신은 여기에 내가 기능을 체인 해요 것으로,

JSONObject obj = jParser.makeHttpRequest(url_all_products, "GET", params); 
String totalOnline = obj.getJSONArray('online').getJSONObject(0).getString('Total Online'); 

참고해야 할 것입니다.

JSONObject obj = jParser.makeHttpRequest(url_all_products, "GET", params); 
JSONArray online = obj.getJSONArray('online'); 
JSONObject firstOnlineObject = online.getJSONObject(0); 
String totalOnline = firstOnlineObject.getString('Total Online');
