You can disable the Button and re-enable it after you are done e.g.

 final Button download= (Button)findViewById(R.id.download);
 @Override
 public void onClick(View view) {
      download.setEnabled(false);
      download.setAlpha(.2f); // grey it out
      String path="http://xxxx.com/sound/ok.mp3";
      file_download(path);
 }

use below code. 

      public void onClick(View view) {

                        String path="http://xxxx.com/sound/ok.mp3";
                        file_download(path);
download.setEnable(false);

                    }

if you do not want to disable your button then u can set a flag like:

int flag = 0;
 public void onClick(View view) {
if(flag == 0)
{                String path="http://xxxx.com/sound/ok.mp3";
                file_download(path);
flag += 1;
}


            }
