android开发app时setAutoCancel(true)无效

在开发开发app时，发现设置了setAutoCancel(true)，但是点击通知后，通知没有消失，还在状态栏中，代码如下

PendingIntent pi=PendingIntent.getActivity(this,0,intent,0); Notification notification=new NotificationCompat.Builder(this,"alarm") .setSmallIcon(R.mipmap.ic_launcher_round) .setLargeIcon(BitmapFactory.decodeResource(getResources(),R.mipmap.ic_launcher_round)) .setContentTitle("闹钟") .setContentText("id="+alarmID) .setSound(Uri.parse("android.resource://"+getApplicationContext().getPackageName()+ "/"+R.raw.bell)) .setPriority(NotificationCompat.PRIORITY_HIGH) .setVisibility(NotificationCompat.VISIBILITY_PUBLIC) .setSound(Uri.parse("android.resource://"+getApplicationContext().getPackageName()+ "/"+R.raw.bell)) .setContentIntent(pi) .setAutoCancel(true)//点击通知后，通知自动消失 .build(); notification.flags=Notification.FLAG_INSISTENT;//将重复音频，直到取消通知或打开通知窗口 notification.fullScreenIntent=pi; notificationManager.notify(alarmID,notification);

 

最后发现，是因为notification.flags=Notification.FLAG_INSISTENT；影响了，因为setAutoCancel和notification.flags设置的是同一个标志位，所有最后notification.flags把之前的设置重置了。发现问题后，代码做了如下修改，就可以把问题解决了

PendingIntent pi=PendingIntent.getActivity(this,0,intent,0); Notification notification=new NotificationCompat.Builder(this,"alarm") .setSmallIcon(R.mipmap.ic_launcher_round) .setLargeIcon(BitmapFactory.decodeResource(getResources(),R.mipmap.ic_launcher_round)) .setContentTitle("闹钟") .setContentText("id="+alarmID) .setSound(Uri.parse("android.resource://"+getApplicationContext().getPackageName()+ "/"+R.raw.bell)) .setPriority(NotificationCompat.PRIORITY_HIGH) .setVisibility(NotificationCompat.VISIBILITY_PUBLIC) .setSound(Uri.parse("android.resource://"+getApplicationContext().getPackageName()+ "/"+R.raw.bell)) .setContentIntent(pi) //.setAutoCancel(true)//不要在这里设置，用flags设置 .build(); notification.flags=Notification.FLAG_INSISTENT|Notification.FLAG_AUTO_CANCEL;//将重复音频，直到取消通知或打开通知窗口，且设置点击通知后，通知自动消失 notification.fullScreenIntent=pi; notificationManager.notify(alarmID,notification);
