TimerTask 使用记录

MyTimerTask.instance(120)?.start(object : MyTimerTask.OnTimerTaskUI {            override fun onUI(time: Int) {            }        })

/** * Created by zxy on 2020/7/21 14:17 * ****************************************** * * * ****************************************** */class MyTimerTask : TimerTask {    private var maxTime = 0    private var time = -1    val mTimer = Timer()    private lateinit var onTimerTaskUI:OnTimerTaskUI    interface OnTimerTaskUI{        fun onUI(time:Int)    }    //zxy 单例模式    private constructor(maxTime: Int) {        this.maxTime = maxTime    }    companion object {        @Volatile        private var instance: MyTimerTask? = null        fun instance(maxTime: Int): MyTimerTask? {            if (instance == null) {                synchronized(MyTimerTask::class.java) {        日语谐音大全           柏拉图简介 if (instance == null) {                        instance = MyTimerTask(maxTime)                    }                }            }            return instance        }    }    override fun理事会决议 run() {        time-=1        onTimerTaskUI.onUI(time)    }    /**     * 开游子吟始     */    fun start(onTimerTaskUI:OnTimerTaskUI,step: Long = 1000) {        this.onTimerTaskUI骨碎补是什么 =onTimerTaskUI        mTimer.schedule(this, 0, step)    }}
