在柔性移動應用程序中處理多個音頻流

我目前正在嘗試編寫一個應用程序，該應用程序可以從多個來源進行流式傳輸，我將以列表形式提供這些應用程序。我希望用戶點擊列表中的選項，然後點擊「播放」按鈕，並開始流式傳輸。我的代碼現在正在工作，但我已明確聲明瞭我想播放的流，但我還沒有找到一種方法將url動態傳遞到req新的URL請求。代碼如下>在柔性移動應用程序中處理多個音頻流

使用stationList.selectedItem，SOR的是這樣的：

private function playAudio():void 
    { 
     if (playingBln == true) 
     {playingBln = false; 
      channel.stop(); 
      s.close() 
     } 
     var streamURL :String = stationList.selectedItem.streamURL; 
     req = new URLRequest(streamURL); 
     s = new Sound(req, context); 
     channel = s.play(); 
     playingBln = true 
    }

我還調整了你的算法，所以你沒有相同的代碼兩個獨立的部分。
