android - Android Oreo上的NotificationManagerCompat

使用NotificationManagerCompat和NotificationCompat时，是否可以在Android Oreo上设置 channel ？

最佳答案

由于NotificationManagerCompat只是使生活更轻松的包装器类，因此可以正常创建 channel :

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    val name = getString(R.string.channel_title)
    val description = getString(R.string.channel_description)
    val importance = NotificationManager.IMPORTANCE_HIGH
    val mChannel = NotificationChannel(CHANNEL_ID, name, importance)
    mChannel.description = description
    mChannel.enableLights(true)
    mChannel.lightColor = Color.parseColor("#5B3C88")
    mChannel.enableVibration(true)
    mChannel.vibrationPattern = longArrayOf(100, 200, 300, 400, 500, 400, 300, 200, 400)
    val manager = (context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager)
    manager.createNotificationChannel(mChannel)
}

然后在发布通知时使用NotificationManagerCompat，但不要忘记使用新的构造函数构造通知:

NotificationCompat.Builder(context, CHANNEL_ID)
