问题 I am adding the new HeadsUp notification to my Android app to be shown as an incoming call which will ring for 30 or 40 seconds. The default HeadsUp notification just ring for 10 seconds and then stops. I searched for a while to find a way to make the notification ring for 30 or 40 seconds. It seems that there is nothing could make me control the Notification Ringing duration. Answering my question This was my updated notification initialization code to answer my question: Notification

问题 I am working with a spell dataset that has the following form: clear all input persid start end t_start t_end spell_type year spell_number event 1 8 9 44 45 1 1999 1 0 1 12 12 60 60 1 2000 1 0 1 1 1 61 61 1 2001 1 0 1 7 11 67 71 1 2001 2 0 1 1 4 85 88 2 2003 1 0 1 5 7 89 91 1 2003 2 1 1 8 11 92 95 2 2003 3 0 1 1 1 97 97 2 2004 1 0 1 1 3 121 123 1 2006 1 1 1 4 5 124 125 2 2006 2 0 1 6 9 126 129 1 2006 3 1 1 10 11 130 131 2 2006 4 0 1 12 12 132 132 1 2006 5 1 1 1 12 157 168 1 2009 1 0 1 1 12

问题 How can I recover the integer corresponding to an ActiveSupport::Duration object? At the same time, is it possible to recover the type of time duration? exemple: foo = 2.day bar = foo.duration_integer # expected "2" baz = foo.duration_type # expected "day" or "days" 回答1: You can use the parts accessor like this. The first element is what you call the duration_type and the last one the integer value: 2.day.parts => [:days, 2] 来源： https://stackoverflow.com/questions/28647309/how-to-recover-an

问题 I have a question concerning SAS and the analysis of the duration of a certain state of a variable. I want to find how long each individual in my dataset stays in state a continiously until state b occurs. If state c occurs after state a the duration should be set to zero. Note that I would also set the duration to zero if pre_period is in state a, but if I get another state a afterwards that should be counted. The data looks kindof like this: pre_period week1 week2 week3 week4 week5 week6

问题 I’m trying to get the duration in seconds of every object in a list but I’m having some trouble in my results. I think it’s because I’m not fully understanding asynchronous behavior. I start my function with an array songs[] of n number of objects. By the end of my function, the goal is to have an array songLengths where the first value is the duration of the first object in songs[] , and so on. I’m trying to model my function after this example: JavaScript closure inside loops – simple

问题 I'm trying to calculate the difference between two UNIX timestamps (i.e. seconds since 1970). I want to say e.g. "3 years, 4 months, 6 days, etc" but I don't know how to account for leap years and months of different durations. Surely this is a solved problem..? This is different to other questions which want to express an approximate duration in one unit that has a fixed/homogeneous duration (e.g. 3 hours, or 7 weeks, etc.). Results for 1. Jan to 1. Feb would be "1 month" and results for 1.

问题 I need to store song durations in minutes/seconds, I need to use TIME, but how would I refer to a certain duration when I am writing an INSERT statement? My datatype in the table is already TIME, should I just STR_TO_DATE the string value of "4:29"? 回答1: First, take a look here: http://dev.mysql.com/doc/refman/5.0/en/time.html Be careful about assigning abbreviated values to a TIME column. MySQL interprets abbreviated TIME values with colons as time of the day. That is, '11:12' means '11:12

问题 I am trying to implement an ETA feature Using System.nanoTime() startTime = System.nanoTime() Long elapsedTime = System.nanoTime() - startTime; Long allTimeForDownloading = (elapsedTime * allBytes / downloadedBytes); Long remainingTime = allTimeForDownloading - elapsedTime; But I cannot figure how to get a human readable form of the nanoseconds; for example: 1d 1h , 36s and 3m 50s . How can I do this? 回答1: If remainingTime is in nanoseconds , just do the math and append the values to a

问题 Is there a way to preload the duration before pressing play the first time on an audio player. I know you can use { duration: 120 } which is fine if every clip is 120 seconds long. I do not have the information available in the database to dynamically populate this variable so there must be another way to tweak the MediaElement.JS script to do it. Any thoughts anyone? 回答1: I don't think mediaelement.js has a way of getting the duration before all or part of the file has been downloaded. You

问题 Is there a YouTube GData API parameter for a query that will only return entries with a minimum and/or a maximum given duration? I've found the "duration" parameter but it only accepts the values "short", "medium", and "long". 回答1: Ok, found it! You need to integrate such query conditions into the fields parameter, which operates on a syntax similar to xpath: http://gdata.youtube.com/feeds/api/videos?fields=entry[*videoVariable* operator *value*] So for what I was looking for, the fields
