Android의 텍스트 뷰로 진행률 막대를 얻으려면 어떻게해야합니까?

Question

나는 다운로드 관리자를 사용하여 인터넷에서 파일을 다운로드하고 활동에 진행률 막대를 추가했습니다. 진행률 표시 줄에 따라 파일을 다운로드하는 비율을 Android의 텍스트 상자에 표시하려고합니다. 이것은 내가 지금까지 시도한 것이다.

protected ProgressBar mProgressBar; 
protected long downloadId; 
private DownloadManager downloadmanager; 


public void startDownload() { 


    String servicestring = Context.DOWNLOAD_SERVICE; 

    downloadmanager = (DownloadManager) getSystemService(servicestring); 

    Uri uri = Uri 
      .parse("http://filename.mp3"); 
    DownloadManager.Request request = new DownloadManager.Request(uri); 



    request.setDestinationInExternalPublicDir("/Download", "Sinhala.mp3"); 
    downloadId = downloadmanager.enqueue(request); 

    mProgressBar = (ProgressBar)findViewById(R.id.progress_bar); 
    Timer myTimer = new Timer(); 
    myTimer.schedule(new TimerTask() { 
     @Override 
     public void run() { 
      DownloadManager.Query q = new DownloadManager.Query(); 
      q.setFilterById(downloadId); 
      Cursor cursor = downloadmanager.query(q); 
      cursor.moveToFirst(); 
      int bytes_downloaded = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR)); 
      int bytes_total = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES)); 
      cursor.close(); 

      final int dl_progress = (bytes_downloaded * 100/bytes_total); 

      runOnUiThread(new Runnable(){ 
       @Override 
       public void run(){ 

        mProgressBar.setProgress(dl_progress); 

       } 
      }); 

     } 

    }, 0, 10); 

}

} 그것은 작동하지 않습니다
