Andorid to achieve the countdown can be snapped (days and seconds) _andorid

Today's project used to buy the countdown function, today to find a lot of buddies, but also Baidu a lot, but did not like and can digest. Finally found a can easily read, but not meet the needs I want, so I do it. I don't know if it's easy, but at least the project's functionality can be achieved. (one afternoon, not in vain.) Happy)
directly on the code well, I believe all can understand. Except me. (I've been doing this all afternoon) Anyway, now I know something.
