Question

Intent intent = new Intent(this, SplashActivity.class);
                Bundle bundle = new Bundle();
                bundle.putString("splash", psd);
                bundle.putString("targetId", targetId);
                intent.putExtras(bundle);
                intent.setAction(psd);
                intent.setAction(targetId);
                intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_NEW_TASK);
                PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), id, intent,
                        0);


                Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
                NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
                        .setSmallIcon(android.R.drawable.ic_notification_overlay)
                        .setContentTitle(title)
                        .setContentText(remoteMessage.getData().get("body"))
                        .setAutoCancel(true)
                        .setStyle(new NotificationCompat.BigTextStyle().bigText("" + remoteMessage.getData().get("body")))
                        .setContentIntent(pendingIntent)
                        .setSound(defaultSoundUri);

                NotificationCompat.InboxStyle inboxStyle =
                        new NotificationCompat.InboxStyle();
                String[] events = new String[6];
                inboxStyle.setBigContentTitle("" + title);
                for (int i = 0; i < events.length; i++) {
                    inboxStyle.addLine(events[i]);
                }

                //.setContentIntent(pendingIntent);
                NotificationManager notificationManager =
                        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
                notificationManager.notify(id, notificationBuilder.build());

它曾经有效，不知道Android O等新Android设备上发生了什么。我没有尝试回旧设备，但它发生在像素上。

Answer 1

从Android 8.0（API级别26）开始，所有通知都必须是分配到一个频道。对于每个频道，您可以设置视觉和应用于该通知中的所有通知的听觉行为渠道。然后，用户可以更改这些设置并确定哪个来自您应用的通知渠道应该是侵入性的或可见的所有

Notification channels

Answer 2

我自己想出了这个，你需要在奥利奥设置频道，在问题上看我的previous post - 我虽然这是一个主要细节问题！事实证明奥利奥有一个你需要的额外属性，但如果你不提供它，它似乎会无声地失败。

Answer 3

设置通知渠道。下面的示例代码

   public static void createNotificationChannel(final Context context, final 
          String channelId, final CharSequence channelName, final String channelDescription, final int importance, final boolean showBadge) {

    try {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            postAsyncSafely("createNotificationChannel", new Runnable() {
                @Override
                public void run() {

                    NotificationManager notificationManager = (NotificationManager) context.getSystemService(NOTIFICATION_SERVICE);
                    NotificationChannel notificationChannel = new NotificationChannel(channelId, channelName, importance);
                    notificationChannel.setDescription(channelDescription);
                    notificationChannel.setShowBadge(showBadge);
                    notificationManager.createNotificationChannel(notificationChannel);
                    Logger.i("Notification channel " + channelName.toString() + 
                   " has been created");

                }
            });
        }
    }catch (Throwable t){
        Logger.v("Failure creating Notification Channel",t);
    }

}

尝试此代码对我来说非常合适。

        Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

        PendingIntent resultPendingIntent = PendingIntent.getActivity(this, 0, resultIntent, PendingIntent.FLAG_CANCEL_CURRENT);

        NotificationCompat.InboxStyle inboxStyle = new NotificationCompat.InboxStyle();

        inboxStyle.addLine(message);

        NotificationManager mNotificationManager = (NotificationManager) getApplicationContext().getSystemService(Context.NOTIFICATION_SERVICE);

        if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext(),"channel_01")
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentText(message)
                    .setContentIntent(resultPendingIntent)
                    .setAutoCancel(true)
                    .setPriority(Notification.PRIORITY_HIGH)
                    .setChannelId("channel_01")
                    .setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION))
                    .setStyle(inboxStyle)
                    .setContentTitle(Title);

            mNotificationManager.notify(Notification_ID, mBuilder.build());

            NotificationChannel channel = new NotificationChannel(Notification_ID, "Playback Notification", NotificationManager.IMPORTANCE_HIGH);
            channel.enableLights(true);
            channel.enableVibration(true);
            channel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
            assert mNotificationManager != null;
            mBuilder.setChannelId("channel_01");
            mNotificationManager.createNotificationChannel(channel);

        }else {
            NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext(),Notification_ID)
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentTitle(Title)
                    .setContentIntent(resultPendingIntent)
                    .setContentText(message)
                    .setStyle(inboxStyle)
                    .setSound(soundUri)
                    .setAutoCancel(true);
            mNotificationManager.notify(Notification_ID, mBuilder.build());
        }
