android处理程序.postdelay（）每次分钟更改时钟？

Question

i want to delay post till the minute change on clock. currently i am using this

handler.postDelayed(drawRunner, 60000);

but this delay post 60 seconds from the time right now. what i want to do is delay the post till minute change on the clock.

for example: lets say time on my phone is 4:15:29 than i want to delay it till the time 4:16:00 and then the next is 4:17:00 and so on.

is there anyway to do this??

Answer 1

You can access the current time by:

long time = System.currentTimeMillis();

After you have that, you can get the second part of it by:

int seconds = new Date(time).getSeconds();

Then you can substract that from 60, and get the sleep time.

int sleepSecs = 60 - seconds;

Then set that to sleep time to handler.postDelayed()

handler.postDelayed(drawRunner, sleepSecs*1000);

After the first time you use this, you can use a constant 60000 millisecond sleeptime.

Please note, that getSeconds() can return 60 or 61 as second value! Documentation

是的，您可以使用此 Timer类来安排定期任务，这样您就可以根据需要在任何时间段内更改Clock时间。
