notificaion-Android 累計未讀通知的數量

Android 累計未讀通知的數量

我在android應用程序中設置了通知功能。每當我接收到一個通知時，未讀通知的數量就累計。使用 notification.number 函數，代碼如下：

NotificationManager notificationManager = (NotificationManager) 
getSystemService(NOTIFICATION_SERVICE);
Notification notification = new Notification(R.drawable.icon,
"A new notification", System.currentTimeMillis());
notification.flags |= Notification.FLAG_AUTO_CANCEL;
notification.number += 1;
Intent intent = new Intent(this, NotificationReceiver.class);

PendingIntent activity = PendingIntent.getActivity(this, 0, intent, 0);
notification.setLatestEventInfo(this, "This is the title",
"This is the text", activity);
notificationManager.notify(0, notification);

但是現在不管接收到多少通知，未讀通知的數量沒有增加，它總是只顯示1.
大家能幫我看看錯誤出現在哪嗎？

最佳回答：

問題是你創建了一個新的通知對象。只需創建一次,檢查它是否存在

public class main extends Activity {

Notification notification=null;


//....
if (this.notification == null)
    this.notification = new Notification(R.drawable.icon,
        "A new notification", System.currentTimeMillis());

this.notification.flags |= Notification.FLAG_AUTO_CANCEL;
this.notification.number += 1;
