You can have a look at AsynTask. Amongst others there are three methods which can serve your requirement.

onPreExecute, onPostExetcute and doInBackground;

Hope that will serve your purpose.

try this way in post execute display your database from database. and pre execute start dialog and post execute close it. if you want to show horizontal incrementing progress bar then in do in backgrond put that code that i have there.

private class DownloadImageTask extends AsyncTask {

protected Bitmap doInBackground(String... urls) {

          while (myProgress<length){
                 myProgress=myProgress+1;  
                 myProgressBar.setProgress(myProgress);

          }
           return decodeImage(urls[0]);
      }

      protected void onPostExecute(Bitmap result) {
          dialog.dismiss();
          imView.setImageBitmap(result);
      }           protected void onPreExecute() {
  // Things to be done while execution of long running operation is
           in progress. For example updating
             ProgessDialog dialog = ProgressDialog.show(BusinessCardActivity.this,
            "Loading.........", "Wait For Few Second", true);             }
  }
