CountDownTimer:如何增加而不是减少计时器

Question

我只想增加CountDownTimer，而不是减少。我知道，我必须修改"mTimeInMillis"，但我不知道如何以及在哪里。你能帮帮我吗？谢谢代码：">

private var startTime = 100000L
private var increaseTime = +10000L
private var mTimer : CountDownTimer? = null
private var mTimerRunnning = false
private var mTimeInMillis = startTime
private fun updateCountDownText(){
var minutes  = (mTimeInMillis/1000).toInt()/60 //  div.Millis in Sekunden,dann div. in Minuten
var seconds  = (mTimeInMillis/1000).toInt()%60  // div.Millis in Sekunden
var timeFormatted : String = String.format("%02d:%02d", minutes, seconds)
tvTime.text = timeFormatted
}

private fun startTimer() {
// mTimer = new CountDownTimer(timeLeftInMillis,1000){// ANDROID
if(!mTimerRunnning){
mTimer?.start()
}
mTimer = object  : CountDownTimer(mTimeInMillis,1000){
override fun onTick(millisUntilFinished: Long) {
mTimeInMillis= millisUntilFinished
mTimeInMillis++
updateCountDownText()
}

增加mTimeLeftInMillis变量？？？但是如何以及在哪里？？谢谢

Answer 1

okay. instead of changing the mTimeInMillis, which i was not able to, i used 2 vars.to let the Countdowntimer count up:
internal var min = 0
internal var sec = 0
then i changed the updateCountDownText to:
private fun updateCountDownText(){
if (sec == 59) {
sec = 0
min = min + 1
val timeMinSec = String.format(Locale.getDefault(), "%02d:%02d", min, sec)
tvTime.setText(timeMinSec)
} else {
sec = sec + 1
val timeMinSec = String.format(Locale.getDefault(), "%02d:%02d", min, sec)
tvTime.setText(timeMinSec)
}
}
and at last , i used the updateCountDownText in the startTimer function:
private fun startTimer() {
mTimer = object : CountDownTimer(1000000000, 1000) {
override fun onTick(millisUntilFinished: Long) {
updateCountDownText()
}
