Android 点击后立即清除通知

Question

我想创建一个用户无法通过向左或向右拖动来关闭它的通知。用户必须单击它才能关闭通知

我的代码是：

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http://google.com"));
PendingIntent pIntent = PendingIntent.getActivity(getApplicationContext(), 0, intent, 0);
Notification n  = new Notification.Builder(getApplicationContext())
                     .setContentTitle("title")
                     .setContentText("text")
                     .setSmallIcon(R.drawable.ic_tt)
                     .setLargeIcon( BitmapFactory.decodeResource(getApplicationContext().getResources(), R.drawable.ic_tt))
                     .setContentIntent(pIntent)
                     .setDefaults(Notification.DEFAULT_SOUND)
                     .setOngoing(true).build();
                     n.flags |= Notification.FLAG_ONGOING_EVENT;

    NotificationManager notificationManager =(NotificationManager) getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(0, n);

但是不起作用有什么想法吗？

您需要同时使用这两个功能才能保留通知，

nBuilder.setOngoing(true);
nBuilder.setAutoCancel(true);

只有用户点击它才能取消。在此Managing Notifications中找到setAutoCancel。希望这对您有所帮助！
