如何将一去使用谷歌-API的Java客户端解析事件的开始和结束时间在用户的谷歌日历？

How would one go about parsing the start and end times of events in a users Google Calendar using the google-api-java-client?

在安装这个的示例Android项目由谷歌code，我可以进入我的谷歌日历和分析的一些信息，（像所有的日历，事件名字，当它被公布，并且摘要），但我不能为我的生命得到事件开始和结束时间。

After installing this sample android project from Google code, I can get into my Google calendar and parse some information, (like all the calendars, the event names, when it was published, and the summary), but I cannot for the life of me get the event start and end times.

我的code的理解是这样。

My understanding of the code is as such.

里面的主要活动类（CalendarAndroidSample.java）这是得到的称号，我的每个日历的方法：

Inside the main activity class (CalendarAndroidSample.java) this is the method that gets the title for each of my calendars:

void executeRefreshCalendars() {
String[] calendarNames;
List<CalendarEntry> calendars = this.calendars;
calendars.clear();
try {
  CalendarUrl url = CalendarUrl.forAllCalendarsFeed();
  // page through results
  while (true) {
    CalendarFeed feed = client.executeGetCalendarFeed(url);
    if (feed.calendars != null) {
      calendars.addAll(feed.calendars);
    }
    String nextLink = feed.getNextLink();
    if (nextLink == null) {
      break;
    }
  }
  int numCalendars = calendars.size();
  calendarNames = new String[numCalendars];
  for (int i = 0; i < numCalendars; i++) {
    calendarNames[i] = calendars.get(i).title;
  }
} catch (IOException e) {
  handleException(e);
  calendarNames = new String[] {e.getMessage()};
  calendars.clear();
}

for循环上面分配每个日历的标题在我的帐户添加到字符串数组calendarNames []。

The for-loop above is assigning the title of each calendar in my account to the string array "calendarNames[]."

我已经想通了，在项目内（Entry.java）内的separete的java文件中找到此处的@key注释指示code解析XML元素和字符串的名称应与该元素的名称。

I have figured out that within a separete java file inside the project (Entry.java) found here, the @Key annotation directs the code to parse an XML element and the name of the string should match the name of the element.

public class Entry implements Cloneable {

@Key
public String summary;

@Key
public String title;

@Key
public String updated;

@Key
public String published;

@Key("link")
public List<Link> links;

@Override
protected Entry clone() {
  try {
    @SuppressWarnings("unchecked")
    Entry result = (Entry) super.clone();
    Data.deepCopy(this, result);
    return result;
  } catch (CloneNotSupportedException e) {
    throw new IllegalStateException(e);
  }
}

String getEditLink() {
  return Link.find(links, "edit");
}
}

所以......

So....

  @Key
  public String published;

...会发现在一个名为发布的XML元素和元素的值分配给字符串。

...would find the element in the XML named "published" and assign the value of that element to the string.

因此​​，返回到第一引用的Java方法executeRefreshCalendars（）（内CalendarAndroidSample.java），改变

Thus, returning to the first referenced java method executeRefreshCalendars() (inside CalendarAndroidSample.java), changing

calendarNames[i] = calendars.get(i).title;

到

calendarNames[i] = calendars.get(i).published;

给我的事件的发布日期。

gives me the date the event was published.

我觉得我在考虑的问题，以了解该code是一个事件的开始和结束时间，数据就在于有两个部分的XML元素中。

I think my problem in regard to understanding this code is that for an event's start and end time, the data lies within an XML element that has two parts.

谁能帮我获得关于如何做到这一点的一些见解？我有超过10个标签在我的浏览器打开，并到处找对苏的帮助就这个问题和最接近我能找到帮助我是this职位，但我无法弄清楚如何使用示例项目我正在与执行。

Can anyone help me gain some insight on how to do this? I have more than 10 tabs open in my browsers and have looked everywhere on SO for help on this and the closest thing I can find to helping me is this post, but I can't figure out how to implement it with the sample project I'm working with.

感谢。

推荐答案

您需要使用EventFeed，并采取一看EventEntry类

You'll need to use the EventFeed and take a look at the EventEntry class

http://$c$c.google.com/p/google-api-java-client/source/browse/calendar-v2-atom-oauth-sample/src/com/google/api/client/sample/calendar/v2/model/EventEntry.java?repo=samples

凌动字符串返回一个包含了开始时间/结束将是这样的：

The Atom string returned containing the startTime / endTime will look like this :

<gd:when startTime='2010-03-13T14:00Z' endTime='2010-03-13T14:30Z'/>

它为蓝本的EventEntry类是这样的：

It's modelled in the EventEntry class like this :

@Key("gd:when")
public When when;

（一为当对象的属性，映射使用@key注释）

(a property for the When object, mapped using the @Key annotation)

的对象时，模型的开始时间/结束的当对象的属性。

The When object, models the start/endTime attributes on the When object

@Key("@startTime")
public DateTime startTime;

@Key("@endTime")
public DateTime endTime;

客户端code与eventFeed inteacting看起来像这样的时候：

Client code when inteacting with the eventFeed will look like this :

EventEntry event = eventFeed.get(0);
DateTime start = event.when.startDate;
