本文介绍了如何在 Android 中使用 SetGroup() 在 Group 中显示通知?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我尝试使用0"通知 ID 以及唯一通知 ID.也使用 setGroup() 如下所示.它仍然每次都会生成一个新通知.我想合并通知正文并将标题设置为通用.
I have tried using "0" notification id and as well as unique notification id. Also used setGroup() like below. It still generates a new notification every time. I want to merge the notification body and set the title as common.
class MyFirebaseMessagingService : FirebaseMessagingService() {
override fun onMessageReceived(remoteMessage: RemoteMessage?) {
super.onMessageReceived(remoteMessage)
remoteMessage?.let {
sendNotification(it.data["alert"])
}
}
private fun sendNotification(messageBody: String?) {
val channelId = "${this.packageName}-${this.getString(R.string.app_name)}"
val defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val builder = NotificationCompat.Builder(this, channelId).apply {
setDefaults(Notification.DEFAULT_ALL)
setSmallIcon(if (Build.VERSION.SDK_INT >= 21) R.mipmap.ic_launcher else R.mipmap.ic_launcher_round)
setContentTitle(getString(R.string.app_name))
setContentText(messageBody)
setDefaults(NotificationCompat.DEFAULT_SOUND or NotificationCompat.DEFAULT_VIBRATE or NotificationCompat.DEFAULT_LIGHTS)
setStyle(NotificationCompat.BigTextStyle().bigText(messageBody))
priority = NotificationCompat.PRIORITY_DEFAULT
setAutoCancel(true)
setSound(defaultSoundUri)
setGroup(getString(R.string.app_name))
setGroupSummary(true)
}
val manager = getSystemService(NOTIFICATION_SERVICE) as? NotificationManager
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channel = NotificationChannel(channelId, getString(R.string.default_channel_name), NotificationManager.IMPORTANCE_HIGH)
manager?.createNotificationChannel(channel)
}
val intent = Intent(this, DashboardFlowActivity::class.java)
intent.putExtra(DashboardFlowActivity.ISFROMNOTIFICATION, true)
intent.flags = Intent.FLAG_ACTIVITY_NEW_TASK or Intent.FLAG_ACTIVITY_CLEAR_TASK
val pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT)
builder.setContentIntent(pendingIntent)
//manager?.cancelAll()
manager?.notify(this.getString(R.string.app_name), getID(), builder.build())
}
}
private val c = AtomicInteger(0)
private fun getID(): Int {
return c.incrementAndGet()
}
我在这里做错了什么吗?另外,我已经通过了这个答案.setgroup() 在通知中不起作用
Anything I am doing wrong here? Also, I have gone through this answer. setgroup() in notification not working
