[移动开发]Android 类似Ios的时间滚轮控件

之前项目使用的,参考了别人的一个demo,但是原文链接找不到了。。。。

先说如何使用:

//参数1:上下文
//参数2:选中是的ResultHandler回调
//参数3:选择器最早时间
//参数4:选择器的最晚时间(本文用的当前时间)
//参数5:选择器的默认展示时间
val currentCalender = Calendar.getInstance()
val currentDate = DateUtil.format(currentCalender.getTime(), "yyyy/MM/dd")
val timeSelector2 = TimeSelector(this,object :TimeSelector.ResultHandler{
    override fun handle(time: String?) {
        birthday_tv.setText(time)
    }
},"1971/01/01", currentDate, "2001/01/01")

//需要显示可选择的小时数与分钟数时,在后面增加对应的两个参数。这时选择器的小时与分钟也会自动显示
val timeSelector2 = TimeSelector(this,object :TimeSelector.ResultHandler{
    override fun handle(time: String?) {
        birthday_tv.setText(time)
    }
},"1971/01/01", currentDate, "2001/01/01","08:30","20:30")
timeSelector.setMode(TimeSelector.MODE.YMD)
timeSelector.show()

滚动控件是自定义的view,PickerView:
