Flex 国际化

Flex 国际化（demo）

 

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")); 

            } 

        } 

   } 

}
