Android 类似Ios的时间滚轮控件_liuhaha1015_android 滚轮控件

网络 02-07 1915

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()
