flasf cs3 里的liberty 有声音 可以是 mp3 wav 等，右键选 linkage 填入类名（我这里填BTNsound），然后将它拖到场景中，发布出来（我的命名是sound.swf),放到工程src文件夹里。在flex里新建一个 类（我的Loadsound.as）代码如下：
package
{
public class Loadsound
{
[Embed(source="Sound.swf",symbol="BTNsound")]//按钮
public static var btnSound:Class;
}
}
然后在 mxml 里
private var Sbtn:Sound = new Loadsound.btnSound() as Sound;//按钮声音
private var soundVol:SoundTransform = new SoundTransform();//音量
internal function init():void{
soundVol.volume = 1;
}
private function onClink():void{
Sbtn.play(0,0,soundVol);
}
OK！这种方式才是最简单的 最实用的！
方法一：
-------------------------分析------------ 方法二： 官方文档的 在编译器里 按下 ctrl + f12 搜索sound 就有例子，这里不多说！ package { import flash.display.Sprite; import flash.net.URLRequest; import flash.media.Sound; import flash.media.SoundChannel; import flash.text.TextField; import flash.text.TextFieldAutoSize; import flash.events.Event; import flash.events.IOErrorEvent; public class Sound_playExample3 extends Sprite { private var snd:Sound = new Sound(); private var channel:SoundChannel; private var statusTextField:TextField = new TextField(); public function Sound_playExample3(){ statusTextField.autoSize = TextFieldAutoSize.LEFT; var req:URLRequest = new URLRequest(http://av.adobe.com/podcast/csbu_dev_podcast_epi_2.mp3); try { snd.load(req); channel = snd.play(); } catch (err:Error) { trace(err.message); } snd.addEventListener(IOErrorEvent.IO_ERROR, errorHandler); addEventListener(Event.ENTER_FRAME, enterFrameHandler); channel.addEventListener(Event.SOUND_COMPLETE, soundCompleteHandler); this.addChild(statusTextField); } private function enterFrameHandler(event:Event):void { var loadTime:Number = snd.bytesLoaded / snd.bytesTotal; var loadPercent:uint = Math.round(100 * loadTime); var estimatedLength:int = Math.ceil(snd.length / (loadTime)); var playbackPercent:uint = Math.round(100 * (channel.position / estimatedLength)); statusTextField.text = "Sound file"s size is " + snd.bytesTotal + " bytes.n" + "Bytes being loaded: " + snd.bytesLoaded + "n" + "Percentage of sound file that is loaded " + loadPercent + "%.n" + "Sound playback is " + playbackPercent + "% complete."; } private function errorHandler(errorEvent:IOErrorEvent):void { statusTextField.text = "The sound could not be loaded: " + errorEvent.text; } e playing." removeEventListener(Event.ENTER_FRAME, enterFrameHandler); }
