【问题描述】：
我已经为 firebase 推送通知实现了自定义视图。对于自定义视图，我们需要从 push Json 中删除“通知”键，以便即使在应用程序关闭时也可以处理它，如下所示：
{
"data": {
"detail": {
}
},
"to": ""
}
为了创建自定义通知，我使用了以下代码：
private void generateNotification(String title, String message, Intent intent) {
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
String channelId = getString(R.string.default_notification_channel_id);
PendingIntent pendingIntent = PendingIntent.getActivity(this, notificationCount, intent,
PendingIntent.FLAG_CANCEL_CURRENT);
/*
* Custom notification layout
* */
String notificationHeaderText = getResources().getString(R.string.app_name) + " \u2022 "
+ DateUtils.formatDateTime(this, System.currentTimeMillis(), DateUtils.FORMAT_SHOW_TIME);
RemoteViews collapsedView = new RemoteViews(getPackageName(), R.layout.view_collapsed_notification);
collapsedView.setTextViewText(R.id.timestamp, notificationHeaderText);
collapsedView.setTextViewText(R.id.content_title, title);
collapsedView.setTextViewText(R.id.content_text, message);
RemoteViews expandedView = new RemoteViews(getPackageName(), R.layout.view_expanded_notification);
expandedView.setTextViewText(R.id.timestamp, notificationHeaderText);
expandedView.setTextViewText(R.id.content_title, title);
expandedView.setTextViewText(R.id.notification_message, message);
Uri soundUri = Uri.parse(ContentResolver.SCHEME_ANDROID_RESOURCE + "://"+ getApplicationContext().getPackageName() + "/" + R.raw.footer_click);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId)
.setSmallIcon(R.drawable.ic_inkclick_logo_colored)
.setSound(soundUri)
.setGroup(GROUP_KEY_INKCLICK)
.setAutoCancel(true)
.setGroupSummary(true)
.setCustomContentView(collapsedView)
.setCustomBigContentView(expandedView)
.setContentIntent(pendingIntent);
notificationBuilder.setPriority(Notification.PRIORITY_HIGH);
NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
if (manager != null) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
NotificationChannel channel = new NotificationChannel(channelId,
getResources().getString(R.string.default_notification_channel_id), NotificationManager.IMPORTANCE_HIGH);
channel.enableLights(true);
channel.setLightColor(Color.MAGENTA);
channel.setVibrationPattern(new long[]{0, 1000/*, 500, 1000*/});
channel.enableVibration(true);
channel.setShowBadge(true);
AudioAttributes audioAttributes = new AudioAttributes.Builder()
.setContentType(AudioAttributes.CONTENT_TYPE_SONIFICATION)
.setUsage(AudioAttributes.USAGE_NOTIFICATION)
.build();
channel.setSound(soundUri, audioAttributes);
manager.createNotificationChannel(channel);
}
manager.notify(0, notificationBuilder.build());
}
else {
manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (manager != null) {
manager.notify(0, notificationBuilder.build());
}
}
notificationCount += 1;
}
在阅读官方通知徽章文档here 以及stackoverflow 上的其他答案（如this 和this）后，我添加了channel.setShowBadge(true);。
我也尝试卸载应用程序并重新启动设备，但未显示徽章。 设备在 API 28(Pie) 上运行。
【问题讨论】：
-
你有什么运气让它工作吗？我遇到了同样的问题。通知本身显示正常，但无论我尝试什么，通知点都不会出现。

@etrado 我还没有找到任何解决方案。仍在寻找答案。
