通知狀態欄中的活動意圖？

Question

我想從通知欄開始一個活動，但它需要得到一個int。從活動到活動，我只是將一個int插入到intent中，但似乎無法弄清楚爲通知欄添加額外內容的位置？這可能嗎？如果不是，有沒有更好的方法來做到這一點？

public void notifyMe() { 
    int icon = android.R.drawable.presence_away; 
    CharSequence tickerText = "New Task Availible"; 
    long when = System.currentTimeMillis(); 

    Notification notification = new Notification(icon, tickerText, when); 

    Context context = getApplicationContext(); 
    CharSequence contentTitle = "PRISM Task"; 
    CharSequence contentText = "New Task Availible"; 
    Intent notificationIntent = new Intent(this, TextAnswerActivity.class); 
    PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); 
    notificationIntent.putExtra("taskId", 20); //unable to retrieve 20 later 

    notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); 

    final int HELLO_ID = 1; 

    mNotificationManager.notify(HELLO_ID, notification); 
} 

如何，我檢索：

Intent myIntent = getIntent(); 
System.out.println("#######TaskID from Intent ===== " + myIntent.getIntExtra("taskId", -1));

你必須調用創建的PendingIntent這需要notificationIntent作爲參數之前notificationIntent.putExtras（...）。試試這個代碼了：

 Intent notificationIntent = new Intent(this, TextAnswerActivity.class); 
     notificationIntent.putExtra("taskId", 20); 

     PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0); 

     Notification notification = new Notification(icon, tickerText, when); 
     notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent); 

並接收數據：

Bundle b = getIntent().getExtras(); 
    if (b != null) { 
     int taskId = b.getInt("taskId"); 
     System.out.println("############# taskID: " + taskId); 
    }
