Android 共计未读通知的数量
Android 累计未读通知的数量
原问题来自于****问答频道,更多解决方案见:http://ask.****.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;
