android handler .postdelay() everytime minute change on clock?

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??

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

Yes you can use this Timer class to schedule periodic task this way you can change your Clock time in any period of time as you need.
