錯誤意圖receveid在通知活動中（服務中）

我有一個非常奇怪的問題。我已經寫了一個帶有2個SimpleNotifications的服務，由一個Thread調用，但是當我點擊它們來啓動DestinationActiviy時，我發現收到的Intent包含了最後點擊的通知的附加內容。錯誤意圖receveid在通知活動中（服務中）

例如：步驟1）SimpleNotification 2稱爲步驟2）SimpleNotification 1被稱爲步驟3）點擊SimpleNotification 2

結果：DestinationActivity表示：「SimpleNotification1」

你能告訴我爲什麼？我對此感到很驚訝......

這是我服務的代碼：

public class MyLocalService extends Service { 

private final static String LOG_TAG = "MyLocalService"; 

private final static int MAX_NOTIFICATION_NUMBER = 10; 

private final static int SIMPLE_NOTIFICATION_ID = 1; 

private NotificationManager notificationManager;   

private BackgroundThread backgroundThread; 

private Notification notification; 

private PendingIntent pIntent; 
private int notificationNumber; 
private PendingIntent pIntent2; 
private Intent intent; 
private Intent intent2; 

@Override 
public void onCreate() { 
     super.onCreate(); 
     backgroundThread = new BackgroundThread(); 
     backgroundThread.start(); 
     notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
     Log.i(LOG_TAG, "Service Created"); 

} 

public void sendNotification1(){ 
     notification = new Notification(R.drawable.icon,"Simple Notification1", System.currentTimeMillis());    
     notification.flags |= Notification.FLAG_AUTO_CANCEL; 
     intent = new Intent(this, DestinationActiviy.class); 
     intent.putExtra("notificationType", "Simple Notification1"); 
     pIntent = PendingIntent.getActivity(this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);  
     notificationNumber++; 
     notification.number=notificationNumber; 
     notification.setLatestEventInfo(this, "Simple Notification1","Simple Notification Extended", pIntent); 
     notificationManager.notify(1, notification); 
} 

public void sendNotification2(){ 
     // Creiamo la Notification 
     notification = new Notification(R.drawable.icon,"Simple Notification2", System.currentTimeMillis());    
     notification.flags |= Notification.FLAG_AUTO_CANCEL; 
     intent2 = new Intent(this, DestinationActiviy.class); 
     intent2.putExtra("notificationType", "Simple Notification2"); 
     pIntent2 = PendingIntent.getActivity(this, 0, intent2,PendingIntent.FLAG_UPDATE_CURRENT);  
     notificationNumber++; 
     notification.number=notificationNumber; 
     notification.setLatestEventInfo(this, "Simple Notification2","Simple Notification Extended", pIntent2); 
     notificationManager.notify(2, notification); 
} 

@Override 
public int onStartCommand(Intent intent, int flags, int startId) { 
     Log.i(LOG_TAG, "Service Started"); 
     notificationNumber = 0; 
     return super.onStartCommand(intent, flags, startId); 
} 

@Override 
public void onDestroy() { 
     backgroundThread.running = false; 
     super.onDestroy(); 
     Log.i(LOG_TAG, "Service Destroyed"); 
} 

@Override 
public IBinder onBind(Intent arg0) { 
     return null; 
} 


private final class BackgroundThread extends Thread { 
     private final static long MIN_DELAY = 2000L;    
     private final static long MAX_RANDOM_DELAY = 10000L; 
     public boolean running= true; 
     public void run() { 
       Log.i(LOG_TAG, "BackgroundThread Started");      
       Random random = new Random(); 
       while(running && notificationNumber<MAX_NOTIFICATION_NUMBER){ 
         long randomDelay = MIN_DELAY + Math.abs(random.nextInt() %MAX_RANDOM_DELAY); 
         Log.i(LOG_TAG, "Delay is (ms) "+randomDelay); 
         try{ 
           Thread.sleep(randomDelay); 
           } 
         catch(InterruptedException ie){ 

         } 
         sendNotification2(); 
         sendNotification1(); 
       } 
       stopSelf(); 
     } 
} 
}

從MainActivity服務啓動：

public class LocalServiceTestActivity extends Activity { 

private Intent serviceIntent; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    serviceIntent = new Intent(this,MyLocalService.class); 
} 

public void startLocalService(View button){ 
    startService(serviceIntent); 
} 

public void stopLocalService(View button){ 
    stopService(serviceIntent); 
}  
}

而且DestinationActivity：

public class DestinationActivity extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.notification_activity); 
    // Otteniamo le informazioni associate all'Intent 
    Bundle extras = getIntent().getExtras(); 
    if (extras != null) { 
     TextView textView = (TextView) findViewById(R.id.outputView); 
     textView.setText(extras.getString("notificationType")); 
    } 
} 

}

我也嘗試過相同的意圖，具有相同的pendingIntent具有相同的通知或viceversa與不同的Inte nt，pendingIntent（像這樣的代碼）...我不知道如何解決這個問題。請幫助我，謝謝。

這裏沒有足夠的信息。服務在哪裏開始？ – Jivings 2012-01-29 11:16:36

我編輯了我的問題。現在清楚嗎？ :-) – Aerox 2012-01-29 20:45:10

當您創建的PendingIntent這裏第二個提示：

pIntent2 = PendingIntent.getActivity(this, 0, 
       intent2,PendingIntent.FLAG_UPDATE_CURRENT);

指定PendingIntent.FLAG_UPDATE_CURRENT標誌。由於第二個通知和第一個通知是「相同的」（即：它們是同一活動的意圖），因此此標誌防止創建新的PendingIntent。相反，它只是使現有的PendingIntent被新的Extras修改。見documentation for PendingIntent。

所以你得到的是兩個通知，兩個共享相同 PendingIntent。無論您選擇哪一個通知，您都會從第二個通知中獲得附加功能。
