try this.

in run() put code which rewrite your progressbar...

if you want stop timer. use timer.cancel(); and for example start faster timer for finish progress..

imer timer= new Timer();
     timer.schedule(
                    new TimerTask() {
                        @Override
                        public void run() {
                            runOnUiThread(
                                    new Runnable() {
                                        @Override
                                        public void run() {

                                    **thise code run every 100ms**

                                }
                            }
                    );
                }
            }, 0, 100);

it's simply, if you want correctly resolve thise problem use Threats.

Have you tried using AsyncTask?

You should look on Android Threading concepts. and as mentioned remember runOnUiThread for calls that updates your UI.

You should extend a progressbar and handle the images position on it... Here is the AsyncTask example code:

 private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
 protected Long doInBackground(URL... urls) {
     int count = urls.length;
     long totalSize = 0;
     for (int i = 0; i < count; i++) {
         totalSize += Downloader.downloadFile(urls[i]);
         publishProgress((int) ((i / (float) count) * 100));
         // Escape early if cancel() is called
         if (isCancelled()) break;
     }
     return totalSize;
 }

 protected void onProgressUpdate(Integer... progress) {
     setProgressPercent(progress[0]);
 }

 protected void onPostExecute(Long result) {
     showDialog("Downloaded " + result + " bytes");
 }

}

Thanks you bro. I know how can make progress bar to display percent download file. But I want custom dialog progress bar as picture. And I found solution for my problem here. http://stackoverflow.com/questions/19900747/custom-progress-dialog-with-squre-image-rotation-with-asyntask . — Xiao King, Aug 21 '16 at 14:50
