如何获得提醒通知。使用下面的代码，我只能在状态栏上看到三个点，在通知栏中看到一个通知。
Intent intent = new Intent(this, MainActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 , intent,PendingIntent.FLAG_ONE_SHOT);
Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.bip);
Uri defaultSoundUri=RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.bip)
.setContentTitle("Temp")
.setPriority(NotificationCompat.PRIORITY_HIGH)
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0, notificationBuilder.build());

I was having the same problem, but I was using the newer NotificationCompat.Builder()call which requires a channel ID from a NotificationChannel.
我遇到了同样的问题，但我使用的是较新的NotificationCompat.Builder()调用，它需要来自NotificationChannel.
The notification will only appear as a heads-up notification if the NotificationChannelis created with an importance value of NotificationManager.IMPORTANCE_HIGH:
如果NotificationChannel创建的重要性值为 ，则通知只会显示为提醒通知NotificationManager.IMPORTANCE_HIGH：
NotificationChannel channel = new NotificationChannel("channel01", "name",
NotificationManager.IMPORTANCE_HIGH); // for heads-up notifications
channel.setDescription("description");
// Register channel with system
NotificationManager notificationManager = getSystemService(NotificationManager.class);
notificationManager.createNotificationChannel(channel);
Show the heads-up notification:
显示提示通知：
Notification notification = new NotificationCompat.Builder(this, "channel01")
.setSmallIcon(android.R.drawable.ic_dialog_info)
.setContentTitle("Test")
.setContentText("You see me!")
.setDefaults(Notification.DEFAULT_ALL)
.setPriority(NotificationCompat.PRIORITY_HIGH) // heads-up
.build();
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(0, notification);

This code works for me:
这段代码对我有用：
NotificationCompat.Builder mBuilder =
new NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.ic_media_play)
.setContentTitle("My notification")
.setContentText("Hello World!")
.setDefaults(Notification.DEFAULT_ALL)
.setPriority(Notification.PRIORITY_HIGH);
