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"));
}
}
}
}
internation.mxml文件如下：
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" preinitialize="init()">
<mx:Script>
<![CDATA[

private var localizator : Localizator = Localizator.getInstance();
private function init():void {
//初始化时设置的语言是用户系统的语言
var crrlanguage:String = Capabilities.language.toString();//获去用户系统语言
if(crrlanguage == 'zh-CN' ){
localizator.language = 'zh_CN';
}else if(crrlanguage == 'en-US'){
localizator.language = 'en_US';
}else{
Alert.show(crrlanguage+"其他语言");
}
}
private function changeLanguage(language:String):void {
localizator.language = language;
}
