Android 累计未读通知的数量


 
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：
[java]  
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
[java] 
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;
