【问题描述】:
我正在创建一个通过 Firebase Cloud Functions 发送和接收通知的聊天应用。假设我有 2 个朋友,每个朋友向我发送 5 条消息(5 条通知)。当我在我的聊天列表中打开一个聊天时,我希望关闭该聊天的所有通知,而不是其他通知。
目前我只能忽略 1 个通知。如果我收到多个通知,notificationManager.cancel(notificationId) 将不起作用。我不想使用notificationManager.cancelAll(),因为我只想关闭一些通知。
override fun onMessageReceived(remoteMessage: RemoteMessage) {
remoteMessage.notification.let { notification ->
val type = remoteMessage.data[NOTIFICATION_TYPE]
val notificationChannelId = getNotificationChannelId(type)
val soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val intent = Intent(this, HomeActivity::class.java)
val notificationIntent = setIntent(remoteMessage.data)
val stackBuilder: TaskStackBuilder = TaskStackBuilder.create(this)
stackBuilder.addParentStack(HomeActivity::class.java)
stackBuilder.addNextIntent(intent)
stackBuilder.addNextIntent(notificationIntent)
val pendingIntent: PendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT)
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
val notificationBuilder = NotificationCompat.Builder(this, notificationChannelId)
.setContentTitle(notification?.title ?: "")
.setContentText(notification?.body ?: "")
.setStyle(
NotificationCompat.BigTextStyle()
.bigText(notification?.body ?: "")
)
.setSmallIcon(R.drawable.ic_stat)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setSound(soundUri)
.setColor(ContextCompat.getColor(applicationContext, R.color.colorNotification))
.setVibrate(vibrationPattern)
.setContentIntent(pendingIntent)
.setAutoCancel(true)
notify(remoteMessage.data, notificationManager, notificationBuilder)
}
}
private fun notify(
data: Map<String, String>,
notificationManager: NotificationManager,
notificationBuilder: NotificationCompat.Builder
) {
when (data[NOTIFICATION_TYPE]) {
CHAT_MSG -> {
if (data[NotificationUtils.CHAT_ID] != ChatActivity.currentChat) {
notificationManager.notify(
CHAT_MSG_NOTIFICATION_ID,
notificationBuilder.build()
)
}
}
FRIEND_REQUEST -> {
notificationManager.notify(
FRIEND_REQUEST_NOTIFICATION_ID,
notificationBuilder.build()
)
}
}
}
OnStart():
fun dismissNotifications(notificationId: Int) {
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
notificationManager.cancel(notificationId)
}
