如何檢測由NotificationManager發送的通知的發件人/檢測通知欄上的哪個通知已被點擊？

Question

我正在開發GPS應用程序。如果用戶進入預定義區域內部或外部，我的應用程序將通過NotificationManager觸發通知。我的應用可以針對這兩種情況啓動通知。

從onResume（），我總是得到最新的intent.setExtra（）值，而不是intent.setExtra值的點擊通知的值。

的問題是如何檢測對內部區域或區外通知用戶點擊？ （我想在不同的情況下顯示不同的觀點）

是否可以添加一個偵聽器來通知點擊？

這裏是我的代碼尖晶石：

private void displayNotificationMessage(String message, boolean vibrate, boolean playSound, Intent contentIntent, String notificationTag) 
{  

    Notification notification = new Notification(R.drawable.buslogo, message, System.currentTimeMillis()); 

    PendingIntent myPendingIntent = PendingIntent.getActivity(this.getBaseContext(),0, contentIntent,PendingIntent.FLAG_UPDATE_CURRENT); 

    notification.setLatestEventInfo(this, "Friendly Reminder", message, myPendingIntent); 

    contentIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|Intent.FLAG_ACTIVITY_SINGLE_TOP); 

    if (vibrate) 
     notification.vibrate=new long[] {100L, 100L, 200L, 500L}; 

    if (playSound) 
     notification.defaults |= Notification.DEFAULT_SOUND; 


    notification.number = ++notificationCounter; 
    notificationMgr.notify(notificationTag, notificationCounter, notification); 

} 

@Override 
protected void onNewIntent(Intent intent) { 
    Log.i(TAG, "*********** onNewIntent(), intent = " + intent); 
    if (intent.getExtras() != null) 
    { 
     Log.i(TAG, "in onNewIntent = " + intent.getExtras().getString("test")); 
    } 
    super.onNewIntent(intent); 
    setIntent(intent); 
} 

@Override 
public void onResume() { 
    super.onResume(); 
    Log.i(TAG, "*********** Main - onResume()"); 

    Intent intent = this.getIntent(); 
    if (intent.getExtras() != null) 
    { 
     Log.i(TAG, "test = " + intent.getExtras().getString("test")); 
    } 
} 

public void createNotification(String msnContent) 
{ 
    Intent intent = new Intent(); 
    intent.setClass(this, Main.class); 
    Bundle bundle = new Bundle(); 
    bundle.putString("test", msnContent); 
    intent.putExtras(bundle); 
    displayNotificationMessage(msnContent, true, true, intent, "test"); 

}

是否有可能增加一個監聽器通知卡嗒一聲？

對於每種情況使用不同的PendingIntent。如果您只是更改額外功能，請務必在創建PendingIntent時使用FLAG_UPDATE_CURRENT。

我發現這個帖子的解決方案 - Confusing behavior when starting new activity with PendingIntent。此外，感謝CommonsWare的幫助。

我缺少intent.setAction（）。

下面是檢測到通知欄的通知已被點擊的代碼spinet。希望它能幫助有相同問題的其他人。
