duration

问题 I'm porting an iOS app to Android, target API 22. I do a bunch of Date/TimeInterval stuff. I do it all in UTC so it just works for me. I'm struggling with what to use for Android. There's Date (from the beginning of time, ha ha). I guess I could do duration math by converting to/from the time milliseconds attribute. It's not clear to me what zone/rules apply to those. I see people who seem to use Calendars as Date objects and pass those around. That seems a bit off. And then there's the new

问题 I have table T1 with IDs: ID 1 2 I have table T2 with ID and GROUP_TRACKING time because record can be multiple times at specific group. GROUP_TRACKING time is ALN type (STRING) and this cannot be changed but it contains always duration value in hh:mm:ss where hh column always has at least 2 characters but of course it can contain and more characters in case when record has been is some group for very long period of time: ID GROUP GROUP_TRACKING 1 GROUP1 05:55:05 1 GROUP1 10:10:00 1 GROUP2

问题 I try to set my Toast show duration like 1minute. I try this: final Toast toast = Toast.makeText(getApplicationContext(), "MESSAGE", Toast.LENGTH_LONG ); toast.show(); Handler handler = new Handler(); handler.postDelayed(new Runnable() { @Override public void run() { toast.cancel(); } }, 60000); Thanks for your help. 回答1: Since LENGTH_SHORT is 2 seconds (and LENGTH_LONG is 3.5 seconds), try this: for (int i=0; i < 30; i++) { Toast.makeText(this, "MESSAGE", Toast.LENGTH_SHORT).show(); } 回答2:

问题 I am playing a live content (SmoothStreaming) with a set duration in a Chromecast device. Although manifest has a parameter duration, Chromecast doesn't get it (duration: null). I am trying do a seek to forward but Player only seek until 20 seconds later (buffering time). Is there a way to set the duration of a live stream? Or Chromecast doesn't support live seeking? Thanks in advance 来源： https://stackoverflow.com/questions/47031243/chromecast-live-duration

问题 I realise that JSON has no real date format and that using ISO 8601 is a good bet given that's what JavaScript uses. What about a duration? JavaScript has no built in format. I came across ISO 8601 Durations e.g. P3Y6M4DT12H30M5S which I haven't seen used much in the wild. It also looks very verbose and difficult to read. As far as I can see it also does not support milliseconds if you needed that. I'm using C# whose TimeSpan type outputs 1.02:03:04.0050000 for 1 day, 2 hours, 3 minutes, 4
