活動級別的Flex動作腳本代碼

Question

任何人都可以指示一小段代碼來使此進度條在麥克風活動級別上移動。 即，當在麥克風上講話時，進度條應指出它。這也適用於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

您需要為事件添加一個回調函數。 您已將其定義為showMicLevel，但沒有該功能的實現。

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