        @Override
        public void onClick(View arg0) {
             new Thread(){
                 public void run(){
                     HttpDownloader httpDl = new HttpDownloader();
                    String str = httpDl.download("http://www.cnlyric.com/LrcDown/3174/156151.lrc");
                     Log.d("yinan", str);
                 }
            }.start();
