调用countDownTimer

Question

如何在onResume()中调用我的CountDownTimer？

private fun countDownTime(timeOut: Long) {
    object : CountDownTimer(timeOut, 1000) {
        override fun onTick(millisUntilFinished: Long) {
            actionWarning.text = "Please wait: " + millisUntilFinished / 1000
        }
        override fun onFinish() {
        }
    }.start()
}

看起来您需要将CountDownTimer提取到一个字段中：

class YourClass {

    val timer = object : CountDownTimer(timeOut, 1000) {
            override fun onTick(millisUntilFinished: Long) {
                actionWarning.text = "Please wait: " + millisUntilFinished / 1000
            }
            override fun onFinish() {
            }
        }

    private fun countDownTime(timeOut: Long) {
      timer.start()
    }

    fun onResume() {
      timer.whatever()
    }
}
