问题描述
是否可以获取场景中对象的像素位置？很明显，SparkAR内部知道在哪里绘制对象，因此它们是否提供使用此信息的界面？
解决方法
我认为您可以为此使用override fun onMessageReceived(remoteMessage: RemoteMessage) {
super.onMessageReceived(remoteMessage)
val soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION)
val textStyle = NotificationCompat.BigTextStyle()
val title: String
val body: String
if (remoteMessage.data.isNullOrEmpty()) {
title = remoteMessage.notification?.title ?: ""
body = remoteMessage.notification?.body ?: ""
} else {
title = remoteMessage.data["title"] ?: ""
body = remoteMessage.data["message"] ?: ""
}
val notificationBuilder = NotificationCompat.Builder(this,getString(R.string.default_notification_channel_id))
.setContentTitle(title)
.setContentText(body)
.setPriority(NotificationCompat.PRIORITY_DEFAULT)
.setStyle(textStyle)
.setSound(soundUri)
.setSmallIcon(R.drawable.ic_notification_icon)
.setAutoCancel(true) // Dismiss the notification on click.
val notificationManager =
getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
// Since android Oreo notification channel is needed.
setupChannels(notificationManager,notificationBuilder)
// Create pending intent,mention the Activity which needs to be triggered
// when user clicks on notification.
val notificationId = Random.nextInt()
navigateToScreen(notificationBuilder,notificationId,remoteMessage)
val notification = notificationBuilder.build()
notificationManager.notify(notificationId,notification)
}
private fun setupChannels(notificationManager: NotificationManager,notificationBuilder: NotificationCompat.Builder) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
val channelId = getString(R.string.default_notification_channel_id)
val channel = NotificationChannel(channelId,"title",NotificationManager.IMPORTANCE_DEFAULT).apply {
description = "body"
enableLights(true)
enableVibration(true)
lightColor = Color.CYAN
lockscreenVisibility = Notification.VISIBILITY_PUBLIC
canShowBadge()
setShowBadge(true)
}
notificationManager.createNotificationChannel(channel)
notificationBuilder.setChannelId(channelId)
}
}
private fun navigateToScreen(notificationBuilder: NotificationCompat.Builder,notificationId: Int,remoteMessage: RemoteMessage) {
val intent = getNavigationIntent(remoteMessage)
val pendingIntent = PendingIntent.getActivity(this,intent,PendingIntent.FLAG_UPDATE_CURRENT)
notificationBuilder.setContentIntent(pendingIntent)
}
private fun getNavigationIntent(remoteMessage: RemoteMessage): Intent {
val intent = Intent(this,MainActivity::class.java)
intent.putExtra("screen",remoteMessage.data["screen"])
return intent
}
