You better try with AsyncTask  Sample code -   private class YourAsyncTask extends AsyncTask lt Void  Void  Void gt        private ProgressDialog dialog       public YourAsyncTask MyMainActivity activity            dialog   new ProgressDialog activity               Override     protected void onPreExecute             dialog setMessage  Doing something  please wait             dialog show               Override     protected Void doInBackground Void    args               do background work here         return null             Override     protected void onPostExecute Void result                do UI work here         if  dialog isShowing                  dialog dismiss                        Use the above code in your Login Button Activity  And  do the stuff in doInBackground and onPostExecute  Update   ProgressDialog is integrated with AsyncTask as you said your task takes time for processing   Update   ProgressDialog class was deprecated as of API 26

Point one you should remember when it comes to Progress dialog is that you should run it in a separate thread  If you run it in your UI thread you ll see no dialog   If you are new to Android Threading then you should learn about AsyncTask  Which helps you to implement a painless Threads    sample code  private class CheckTypesTask extends AsyncTask lt Void  Void  Void gt           ProgressDialog asyncDialog   new ProgressDialog IncidentFormActivity this           String typeStatus             Override         protected void onPreExecute                   set message of the dialog             asyncDialog setMessage getString R string loadingtype                  show dialog             asyncDialog show                super onPreExecute                        Override         protected Void doInBackground Void    arg0                   don t touch dialog here it ll break the application               do some lengthy stuff like calling login webservice              return null                      Override         protected void onPostExecute Void result                  hide the dialog             asyncDialog dismiss                 super onPostExecute result                  Good luck
