[游戏开发]CountDownTimer实现adapter倒计时

Adapter

}

Fragment 或者activity（释放资源）

override fun onDestroyView() {
    super.onDestroyView()
    if (newSelectMallAdapter != null) {
        try {
            if (newSelectMallAdapter != null) {
                newSelectMallAdapter.clearTimeList()
            }
        }catch (e:Exception){
            e.printStackTrace()
        }

    }
}
