我從不猜測，猜測是一個很壞的習慣——會影響正常的邏輯推理能力。              ——阿瑟·柯南·道爾 《福爾摩斯探案集》

近日，在做安卓專案開發的時候涉及到狀態列通知的需求，查了資料，總結一個簡單有效的方法，下面放上程式碼（Kotlin版）：

//該程式碼為Kotlin，讀者可根據需求稍作調整
    val notificationManager = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    var notification: Notification
    val intent = PendingIntent.getActivity(this,
            100, Intent(this, MainActivity::class.java),
            PendingIntent.FLAG_CANCEL_CURRENT)
    val largeIcon = BitmapFactory.decodeResource(
            this.resources, android.R.drawable.ic_media_play)
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
        val mChannel = NotificationChannel("id", "name",NotificationManager.IMPORTANCE_LOW)
        notificationManager.createNotificationChannel(mChannel)
        notification = Notification.Builder(this)
                .setChannelId("id")
                .setContentTitle("標題")
                .setContentText("內容內容內容內容內容內容內容內容內容內容")
                .setContentIntent(intent)
                .setLargeIcon(largeIcon)
                .setSmallIcon(android.R.drawable.ic_media_play).build()
    }else{
        val builder = NotificationCompat.Builder(this)
                .setContentTitle("標題")
                .setContentText("內容內容內容內容內容內容內容內容內容內容")
                .setDefaults(NotificationCompat.DEFAULT_ALL)
                .setAutoCancel(true)
                .setLargeIcon(largeIcon)
                .setSmallIcon(android.R.drawable.ic_media_play)
                .setContentIntent(intent)
        notification = builder.build()
    }
    notificationManager.notify(0,notification)
