Android 累计未读通知的数量

Question

我在android应用程序中设置了通知功能。每当我接收到一个通知时，未读通知的数量就累计。使用 notification.number 函数，代码如下：

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);

但是现在不管接收到多少通知，未读通知的数量没有增加，它总是只显示1.
大家能帮我看看错误出现在哪吗？

问题是你创建了一个新的通知对象。只需创建一次,检查它是否存在

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;
