封装工具类：

  var pvTime: TimePickerView? = null

    fun showTimePickerDialog(
        context: Context,
        title: String,
        types: BooleanArray,
        curDate: Calendar,
        startDate: Calendar,
        endDate: Calendar,
        listener: OnTimeSelectListener
    ) {

        var mTypes = types
        if (types == null)
            mTypes = booleanArrayOf(true, true, true, true, true, true)
        pvTime = TimePickerBuilder(
            context,
            listener
        )
            .setType(mTypes)
            .setCancelColor(context.resources.getColor(R.color.ty_theme_color_b2_n3))
            .setCancelText(context.resources.getString(R.string.ty_cancel))
            .setSubmitColor(context.resources.getColor(R.color.ty_theme_color_b2_n1))
            .setSubmitText(context.resources.getString(R.string.ty_confirm))
            .setSubCalSize(16)//确定和取消文字大小
//            .setTitleText(title)
//            .setTitleSize(16)
//            .setTitleColor(context.resources.getColor(R.color.ty_theme_color_b2_n3))
            .setContentTextSize(18)//滚轮文字大小
            .setOutSideCancelable(true)
            .setBgColor(context.resources.getColor(R.color.ty_theme_color_b1))
            .setTitleBgColor(context.resources.getColor(R.color.ty_theme_color_b1))//标题背景颜色 Night mode
            .setTextColorCenter(context.resources.getColor(R.color.ty_theme_color_b2_n1))
            .setDate(curDate)
//            .setRangDate(startDate, endDate)
            .apply {
                var country = context.resources.configuration.locale.language
                if(country.equals("zh")){
                    setLabel("年","月","日","时","分","")
                }else{
                    setLabel(" "," "," ","H","M","")
                }
            }
            .build()

        val mDialog = pvTime?.dialog
        if (mDialog != null) {
            val params = FrameLayout.LayoutParams(
                ViewGroup.LayoutParams.MATCH_PARENT,
                450,
                Gravity.BOTTOM
            )
            params.leftMargin = 0
            params.rightMargin = 0
            pvTime?.dialogContainerLayout?.layoutParams = params
            val dialogWindow = mDialog.window
            if (dialogWindow != null) {
                dialogWindow.setWindowAnimations(R.style.picker_view_slide_anim) //修改动画样式
                dialogWindow.setGravity(Gravity.BOTTOM) //改成Bottom,底部显示
            }
        }
        pvTime?.show()
    }

使用示例：

    fun selectStartTime(
        curTime: Long,
        authEndTime: Long,
        onSuccess: (authTime: AuthTime) -> Unit = {},
        onFailure: (msg: String) -> Unit = {}
    ) {
        val types = booleanArrayOf(true, true, true, true, true, false)
        var curDate = Calendar.getInstance()
        if(curTime != 0L)
        curDate.timeInMillis = curTime
        var startDate = Calendar.getInstance().transferDate()
        var endDate = Calendar.getInstance().transferDate()
        endDate.add(Calendar.YEAR, 60)

        showTimePickerDialog(context, getString(R.string.wb_app_securityMonitor_authorize_authorize_start_time), types,curDate, startDate, endDate,
            OnTimeSelectListener { date, v ->
                if (authEndTime != 0L && date.time > authEndTime) {
                    onFailure.invoke(getString(R.string.wb_app_securityMonitor_authorize_start_time_error_hint))
                    return@OnTimeSelectListener
                }

                var timeStr = date.dateFormatToStr("yyyy-MM-dd HH:mm")
                onSuccess.invoke(AuthTime(timeStr, date))
                pvTime?.dismiss()
            })
    }

日期转换方法：

//获取当前日期的下一个整点
fun Calendar.transferDate(): Calendar {
    this.let { instance ->
        var ca = Calendar.getInstance()
        ca.set(Calendar.SECOND, 0)
        ca.set(Calendar.MILLISECOND, 0)
        if (ca.time.time % 3600 == 0L) return this
        ca.add(Calendar.HOUR, 1)
        ca.set(Calendar.MINUTE, 0)
        return ca
    }
}

//日期格式化
fun Date.dateFormatToStr(pattern:String="yyyy-MM-dd HH:mm:ss"):String{
    if(this == null ) return ""
    var format = SimpleDateFormat(pattern)
    return format.format(this)
}

//时间格式化
fun Long?.timeFormatToStr(pattern:String="yyyy-MM-dd HH:mm:ss"):String{
    if(this == null || this == 0L) return ""
    var format = SimpleDateFormat(pattern)
    return format.format(Date(this))
}

 获取今天0点及最后一秒时间:

var startTime = Date(System.currentTimeMillis())
var rawOffset = TimeZone.getDefault().rawOffset
val zero = (startTime+rawOffset) / (1000 * 3600 * 24) * (1000 * 3600 * 24) - rawOffset //今天零点零分零秒的毫秒数
val twelve = zero + 24 * 60 * 60 * 1000 - 1 //今天23点59分59秒的毫秒数

getRawOffset()
该方法以毫秒为单位返回需要添加到UTC以获得此TimeZone中的标准时间的时间。

必须在除数+getRawOffset()方法，否则可能会出现跨天的现象，导致结果是错误的。详情见：获取当天零时时间戳之误区
