活动级别的Flex动作脚本代码

Question

任何人都可以指示一小段代码来使此进度条在麦克风活动级别上移动。 即，当在麦克风上讲话时，进度条应指出它。这也适用于Internet Explorer

 <?xml version="1.0" encoding="utf-8"?>
 <mx:Application
 xmlns:mx="http://www.adobe.com/2006/mxml"
 layout="absolute"
 width="300"
 height="100"
creationComplete="init()">

<mx:Script>
<![CDATA[
 import mx.controls.Alert;
 import flash.net.NetStream;

 private var myMic:Microphone;
 private var recordingState:String = "idle";

 private function init():void {

    myMic = Microphone.getMicrophone();
    myMic.setSilenceLevel(0);
    myMic.rate = 44;
    myMic.gain = 100;

    micLevel.visible = true;
    Security.showSettings(SecurityPanel.MICROPHONE);
    myMic.setLoopBack(true);
    if (myMic != null)
    {
       myMic.setUseEchoSuppression(true);
       micLevel.setProgress(myMic.activityLevel, 100);
       addEventListener(Event.ENTER_FRAME, showMicLevel);
       //micLevel.setProgress(myMic.activityLevel, 100);
    }

 }

<mx:ProgressBar x="0" y="36" mode="manual" id="micLevel" label="" labelPlacement="bottom" width="100" fontSize="10" fontWeight="normal"/>

Answer 1

您需要为事件添加一个回调函数。 您已将其定义为showMicLevel，但没有该功能的实现。

   private function showMicLevel(e: Event):void{
      micLevel.setProgress(myMic.activityLevel, 100);
   }
