Kotlin定时器

class MyTimerTask() : TimerTask() {
    override fun run() {
        uiScope.launch {
            for (i in array.indices) {
                withContext(Dispatchers.Main) {
                    holder.setText(R.id.The_current_value, array[i])
                }
            }
        }
    }
}
val task = MyTimerTask()
Timer().schedule(task, Date(), 300)
