you have to used the ProgressDialog: http://developer.android.com/reference/android/app/ProgressDialog.html

It can show a indeterminate progress bar or a percentage. To update the percentage bar, you'd possibly need to use the class AsyncTask. I put a link which shows the two classes working together: http://sites.google.com/site/androidhowto/how-to-1/asynctasks-with-progressdialogs

I'm adding a more useful link: http://www.codeproject.com/Articles/162201/Painless-AsyncTask-and-ProgressDialog-Usage

Use AsyncTask, it has helpful methods namely

      protected void onPreExecute(){
        //Show a dialog here
     }
      protected void onProgressUpdate(Integer... progress) {
         setProgressPercent(progress[0]);
     }

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

You can publish your percentage progress in onProgressUpdate method and in onPostExcecute dismiss the dialog

You should write the part updating the progressbar as an AsyncTask to see the loading lively. You can also use Handlers.

this can help: http://developer.android.com/reference/android/os/AsyncTask.html
