How to add ProgressDialog

Question

I am downloading a file from dropbox which is taking a few seconds. I want to add a ProgressDialog for the download but I don\'t know how to do that.

Answer 1

See there are actually 4 methods of AsyncTask:

1. onPreExecute() - you can do some pre execution task here.
2. doInBackground() - you can perform some background work here.
3. onPostExecute() - you can perform post execution task here. Means like displaying data in ListView, update TextView, etc.
4. onProgressUpdate() - To update UI while background operation is going on.

So in your case, you can show progress dialog or progress bar inside onPreExecute() method of AsyncTask and dismiss(() the same inside onPostExecute().
