检索和分析数据的iCal通过HTTP在Android [英] Retrieving and parsing iCal data over HTTP on Android
问题描述
我想提出，要求用户输入用户ID的应用程序，附加的用户ID为静态的HTTP链接，检索具有的.iCal（日历）扩展了用户的日常调度信息的文件。
I am making an application that asks the user for userid, appends the userid to a static HTTP link to retrieve the user's daily schedule info file that has a .ical (calendar) extension.
我需要阅读的文件，格式新的用户界面，并重新presenting在Android设备上一些有用的数据的数据。
I need to read the data from file, format in new UI and representing some useful data on an Android device.
我的查询是我可以访问幕后静态HTTP链接？当我使用桌面浏览器相同的链接，它会要求用户将文件保存＆mdash;我怎样才能做到这一点在移动？我需要读取数据，并保存到某个地方或者我可以保存的.iCal文件，并从中读取？
My query is can I access a static HTTP link behind the scenes? And when I use the same link on desktop browser, it asks user to save the file — how can I do this on a mobile? Do I need to read the data and save it somewhere or I can save the .ical file and read from it?
推荐答案
Android设备一般不能处理的iCalendar格式的文件（的.ics）＆mdash;没有办法只是开这样的文件和具有显示的信息。你将不得不写一些code（或使用一个库如 iCal4j ）来解析信息日历文件。
Android devices generally cannot handle iCalendar-formatted files (.ics) — there is no way to just "open" such a file and have the information displayed. You would have to write some code (or use a library such as iCal4j) to parse the information in the calendar file.
根据你的问题和意见，你需要打破这种成几个部分：
Based on your question and comments, you need to break this into a few parts:
- 获取用户的ID在用户界面中输入
-
字符串userid =（（EditText上）findById（R.id.user_id））getText.toString（）;
-
- Get the user's ID entered in the UI
String userId = ((EditText) findById(R.id.user_id)).getText.toString();
-
静态最后弦乐CALENDAR_BASE =http://example.com/cal/;
字符串escapedUserId = URLEn coder.en code（用户ID，UTF-8）;
字符串URL = CALENDAR_BASE + escapedUserId +/ events.ics;
static final String CALENDAR_BASE = "http://example.com/cal/";
String escapedUserId = URLEncoder.encode(userId, "UTF-8");
String url = CALENDAR_BASE + escapedUserId +"/events.ics";
