 [Ruby on Rails]利用google在线翻译制作自己的翻译程序之ruby版
软件技术

| 刚学ruby时写的工具，我自己一直在用，放在桌面上，遇到不懂单词就得问它。发在railscn上，ranchgirl修改的更为ruby way。 受blogjava上的帖子启发，实在是个有趣的主意，写了个ruby版本的，对俺这等英语一般的同学来说，google在线翻译经常使用呐，原贴之java版http://www.blogjava.net/ekinglong/archive/2006/11/12/80704.html?Pending=true#Post

| Activity and Intent - Verb and Data
The GUI toolkit is generally referred to as the VIEW system. Like DALVIK, the VIEW system was specially designed and optimized by Google for running in embedded environments. Mike indicated that coding should be friendly and familiar to anyone who has worked with user interface toolkits before. (This section covers my understanding of some of the newest and most technical aspects of the platform. My understanding is based on a phone conversation with Mike. A clearer picture will quickly develop as we all get a chance to work with the SDK.)
Android takes the idea of an application and breaks it down into bite-sized components—each called an ACTIVITY. As an example, mail is broken down into main components like the following: show a list of email, show email message, create an outgoing message. This componentization should do well in an open source environment where developers can share smaller blocks of code and assemble them into more powerful applications from what is already available. Application-level components or services could be shared for common tasks, such as creating a mail message. It remains to be seen how sharing and distribution of these components evolve, but it's possible that a packaging process similar to Debian and Linux distributions might quickly take hold.
Developers use a general purpose data structure, called an INTENT to describe the object (DATA) the component is working on. A VERB, such as "show," and DATA described by an INTENT carry out the user's wishes and display what is requested. The overall application environment is object oriented, e.g., a VIEW is defined to inherit from a master VIEW class. Messages are passed between the objects to control behaviors. For example, when a user clicks on the HOME button, it doesn't launch software, but passes a message into the Android system which allows the developer an opportunity to change the location and behavior of HOME if you have a legitimate reason for doing so.
Any time you switch between screens displayed on the phone, your INTENTs are processed like URLs, allowing you to easily navigate from point A in an application to point B.
This is a new way of programming for many developers. Google realizes it will take some time for people to see and solve problems as components rather than monolithic programs. |
