duration

I am developing an application for API level 19 (KitKat). I have a LocalDateTime object and a Duration object. I need to add this Duration to LocalDateTime . Android Studio shows that plus(TemporalAmount) method of LocalDateTime class is avaliable since API level 26 which is Oreo and it supports less than 1% of devices right now. How can I do it with API level 19? The bbb answer in the comments is correct. Currently the best option for android is ThreeTenABP . Jake Wharton explains why it's better to use this library rather than Joda-Time and ThreeTenBP in Android. 来源： https://stackoverflow

Friends, In my application Toast message is Displayed in Activity say UserActivity.class.. That activity includes a button, in which it will Redirect to next Activity in OnClick of button.. What i want is that my Toast Message should display in UserActivity until user taps Button, if user Taps the button my toast message has to be Disappear and Next activity will appear.. Is it possible to do like this, if so how its possible? Thanks Venkatesh. RoflcoptrException This is quite simple. Just call the cancel method on your ToastMessage as soon as you don't want to show the ToastMessage anymore.

I have a property field in a class that is of type javax.xml.datatype.Duration . It basically represents a time span (e.g. 4 hours and 34 minutes). JPA is telling me it is an invalid type, which doesn't shock me. Whats a good solution this? I could implement my own Duration class, but I don't know how to get JPA to "accept" it as a datatype. Whats a good solution this? I could implement my own Duration class, but I don't know how to get JPA to "accept" it as a datatype. JPA does not support custom types so if you want to go this way you'll have to use a JPA extension from your provider. For

Is there a way to change the time the iOS keyboard animation takes? I've actually found a better solution. What you can do is programmatically make the textfield or textview a first responder within an animation with duration of your choice. Example for making the keyboard emerge over the course of one second might be: [UIView animateWithDuration:1.0 animations:^ { [myTextField becomeFirstResponder]; }]; Similarly, you can make the keyboard disappear like this: [UIView animateWithDuration:1.0 animations:^ { [myTextField resignFirstResponder]; }]; 来源： https://stackoverflow.com/questions/7542495

I'm trying to format a duration (in seconds) as a time and I'm getting results indicating that I'm supposed to account for an epoch somewhere. I expected os.date("%X", 0) to produce "00:00:00" but it is returning "20:00:00" as well as a date value of "12/31/69" (I don't need a calendar date though). Is there a standard way of getting a time duration string that causes 0 seconds to produce a clock representing a total of zero seconds? I can't seem to find an example anywhere of what I'm trying to do. Thanks In most systems (ie, POSIX), os.date("%X",0) gives you the time of the epoch, which is

Depending on the compiler the following code: int main() { srand( 0 ); if( rand() ) { char buffer[600 * 1024] = {}; printf( buffer ); } else { char buffer[500 * 1024] = {}; printf( buffer ); } return 0; } when ran on a system with maximum stack size equal to 1 megabyte either prints an empty string or crashes with a stack overflow. The difference is because different compilers allocate automatic storage differently. Most compilers allocate storage for all objects on function start , so in the code above they allocate 600+400=1100 kilobytes and that leads to stack overflow. Some compilers are

There are plenty of questions asking how to do this the other way (converting from this format), but I cant find anything on how to output in the ISO 8601 duration format in PHP. So I have a heap of duration strings in human readable format - I want to convert them into the ISO 8601 format on the fly to print the durations for HTML5 microdata. Below is a sample of some of the strings coming in, and how they should be formatted "1 hour 30 minutes" --> PT1H30M "5 minutes" --> PT5M "2 hours" --> PT2H You get the idea. I can push the string into an interval object in PHP: date_interval_create_from
