How to show progress dialog in Android?

Question

I want to show ProgressDialog when I click on Login button and it takes time to move to another page. How can I do this?

Answer 1

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{
        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.
