Android的代碼得到錯誤的登錄是這裏使用web服務
public class NewLogin extends ActionBarActivity {
private EditText editTextUserName;

JSON代碼是在這裏

這裏即時得到無效的用戶名和密碼，請幫我從Android中的JSON文件中獲取用戶的詳細信息 如何解決這個問題誰能告訴我?? 在這裏我得到無效的用戶名和密碼，請幫我從json文件中獲取用戶詳細信息在android 如何解決這個任何人都可以告訴我??
你的API是一個GET請求，但要創建從Android的POST請求。你傳遞給php腳本的鍵也是錯誤的。你的MySQL查詢沒有任何意義。 –
