如何在Android应用程序中点击后隐藏通知

这是在服务开始时发出通知的代码

NotificationCompat.Builder mbuild = new NotificationCompat.Builder(getApplicationContext());

Intent in = new Intent(getApplicationContext(), MainActivity.class);
PendingIntent resultIN =   PendingIntent.getActivity(getApplicationContext(),code,in,NOTIFICATION_COUNT);           mbuild.setSmallIcon(R.drawable.images1);    
mbuild.setContentText(NOTIFICATION_COUNT +" New Message");
mbuild.setContentIntent(resultIN);          //mbuild.addAction(R.drawable.notifications,NOTIFICATION_COUNT +"New Messages",resultIN);

 NotificationManager nmagr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
nmagr.notify(1, mbuild.build());

一切工作正常..代码打开目标活动，但通知仍然保留在通知栏中。 我尝试过使用 msbuild.setautocancel(true);但它什么也没做

try this

NotificationManager nmagr = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            Notification notification=mbuild.build();
            notification.flags = Notification.FLAG_AUTO_CANCEL;
            nmagr.notify(1,notification);
