Android實(shí)現(xiàn)精確到天時(shí)分秒的搶購(gòu)倒計(jì)時(shí)

更新時(shí)間：2022年06月30日 14:30:20 作者：Tab_Esc

這篇文章主要為大家詳細(xì)介紹了Android實(shí)現(xiàn)精確到天時(shí)分秒的搶購(gòu)倒計(jì)時(shí)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

今天項(xiàng)目用到了搶購(gòu)時(shí)倒計(jì)時(shí)的功能，今天找了好多哥們，也百度了好多，但是沒(méi)有自己喜歡并且能消化的。好不容易找到了一個(gè)能容易看懂的，然而又不符合我想要的需求，所以自己搞一下。不知道是否簡(jiǎn)單，但是最起碼是項(xiàng)目的功能可以實(shí)現(xiàn)。（一下午，沒(méi)白費(fèi)。開(kāi)心）

直接上代碼好了，我相信都能看懂。我除外。（我搞了一下午）哎。反正現(xiàn)在懂點(diǎn)了。。。
