Flex 国际化

在项目中新建一个locale的目录(src目录下)；

在locale目录下创建需要支持语言的子目录，如locale/zh_CN, locale/en_US；

在这些子目录下新建properties文件（en_US.properties,zh_CN.properties），各目录下的属性文件需要 同名。属性文件的格式与java的属性文件相同，每行以"key=value"的形式列出键值对，以utf-8编码保存文件；

编译mxml文件时加上 -locale=en_US,zh_CN -source-path=/locale/{locale}的选项；



在flex的sdk下加入中文库（C:\Program Files\Adobe\Flex Builder 3\sdks\3.2.0\frameworks\locale）zh_CN



Localizator.as文件内容如下：



package util {

    

    import flash.events.EventDispatcher;

    import flash.events.IEventDispatcher;

   import flash.events.Event;

    import mx.resources.ResourceBundle;

    

    public class Localizator extends EventDispatcher {

        

        //采用单例模式

        private static var _instance : Localizator;

        

        private var _language : String;

        

        //这里的resource名应与.properties文件名相同

       [ResourceBundle("en_US")]

        private var lang_en_US:ResourceBundle;

       

        [ResourceBundle("zh_CN")]

        private var lang_zh_CN:ResourceBundle;         

        [Bindable]

        private var currRes:ResourceBundle;

        

        public function Localizator(language : String = "en_US") {

            selectLanguage(language);

        }

        

       public static function getInstance(language : String = "en_US"):Localizator {

            if (_instance == null) {

                _instance = new Localizator(language);

            }

            return _instance;      

             }

        private function selectLanguage(language : String):void {

            this._language = language;

            

            if (_language == "en_US") {

                this.currRes = lang_en_US;

            } else if (_language == "zh_CN") {

                this.currRes = lang_zh_CN;

           } else {

               this.currRes = lang_en_US;

            }

        }

        

        [Bindable(event="languageChange")]

        public function getText(key:String):String {

            return this.currRes.getString(key);

       }

        

        public function get language():String {

            return this._language;

       }

           public function set language(language : String):void {

            if (this._language != language) {

                selectLanguage(language);

                dispatchEvent(new Event("languageChange"));

            }

        }

   }

}







internation.mxml文件如下：
