时间表是最近的时间

Question

如何在右边的图片上做最近时间的时间表？对我来说不是，我是新手。请帮我。

--Fragment.java

public class DayFragment extends ListFragment {
String[] time = new String[] { "06:30","06:40","06:48","06:56","07:04","07:12","07:20","07:28","07:36", "07:44",
        "07:52", "08:00", "08:08", "08:16", "08:22", "08:31", "08:40", "08:50", "09:00", "09:10", "09:20",
        "09:30", "09:40", "09:50", "10:00", "10:10", "10:20", "10:30", "10:40", "10:50", "11:00", "11:10",
        "11:20", "11:30", "11:40", "11:50", "12:00", "12:10", "12:20", "12:30", "12:40", "12:50", "13:00",

Answer 1

这是一些新手的伪代码：

 GET your current time -> Time CURRENT_TIME = new Time();

现在，您必须使用time[]的值找到最近的时间。所以你正在寻找索引

 //exact the same time
 time[index] EQUAL CURRENT_TIME  

 OR

 //your current time has to be between your time tables
 time[index] is smaller to CURRENT_TIME &&  time[index+1] is bigger to CURRENT_TIME

在Time对象中，您有after，before和compare（Java:Time）

的功能

小心time[index+1]和ArrayOutOfBoundsException。此时，您必须检查time[index+1]是否存在。如果没有，则最后一次是您要查找的值
