發送請求與JSON到PHP服務器在Android

Question

嗨，我是新來的Android我必須發送我的不同的數據使用JSON到PHP服務器，如 標籤-----學生的詳細信息 學生----- n由具有像學生1 名稱 ID DOB 類 輥沒有 學生2 每個學生 的細節對象。 。 。 .. 學生ň

標籤------老師細節 老師---------- n分別具有類似於 老師的名字 教師ID 司法部每個老師 的細節對象 指定

我已經使用創造試圖名稱值對列表的第一值對是標記 - 學生/教師 其他值對我使用JSON對象創建 - > JSON數組 - > JSON對象（名稱值對） - >教師/學生的詳細信息 任何幫助或示例代碼將被認爲....感謝advan CE

試試這個功能的名字 - 值對張貼到PHP腳本

public void postData(List nameValuePairs){ 
     // Create a new HttpClient and Post Header 
     String url = "http://localhost/recieve.php"; 
     HttpClient httpclient = new DefaultHttpClient(); 
     HttpPost httppost = new HttpPost(url); 

     try { 
      // Add your data 
      //List nameValuePairs = new ArrayList(1); 
      //nameValuePairs.add(new BasicNameValuePair(a, b)); 
      //nameValuePairs.add(new BasicNameValuePair("Number", b)); 
      httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); 

      // Execute HTTP Post Request 
      HttpResponse response = httpclient.execute(httppost); 


     } catch (Exception e) { 
      // TODO Auto-generated catch block 
      e.printStackTrace(); 
      // TODO Auto-generated catch block 
     } 
    } 

發佈該數據使用 - >

List nameValuePairs = new ArrayList(1); 
nameValuePairs.add(new BasicNameValuePair("Number", b)) 
postData(nameValuePairs); 

希望這有助於。

讓它MYPROJECT一個新的項目名稱，然後創建一個活動類，看看上面的示例代碼！
