请考虑以下内容:
var everySunday = Timer()
var timertask = object: TimerTask(){
override fun run(){
var day = Calendar.getInstance().get(Calendar.DAY_OF_WEEK)
var time = SimpleDateFormat("HH:mm:ss", Locale.getDefault()).format(Date()
var midnight = "00:00:00"
if (day == Calendar.Sunday && time == midnight){
Toast.makeText(this, "It's Sunday!", Toast.LENGTH_SHORT).show()
}
}
}
everySunday.scheduleAtFixedRate(timertask, 0, 60000)
基本上,每个周日的功能是通知我,它在星期日的每个凌晨12:00都是星期天。
但是,我想进一步简化EverySunday的代码,仅此一点:
var everySunday = Timer()
var timertask = object: TimerTask(){
override fun run(){
Toast.makeText(this, "It's Sunday!", Toast.LENGTH_SHORT).show()
}
}
//val date = ?? <-- "Sunday 12:00 am"
everySunday.schedule(timertask, date)
问题是我想将日期写为日期!代表星期日12:00 am的类型,但我不确定该怎么做。协助将不胜感激。
