Android 累计未读通知的数量

原问题来自于CSDN问答频道，更多解决方案见：http://ask.csdn.net/questions/1566

 

原问题描述：

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？

 

解决方案：

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;
