How to show a progress bar on screen programatically in Android?
I have a class named BookAdder. It extends AsyncTask and it should add a
list of books on the app. Also some activities call it and I want to show
a progress bar on center of screen when it is called.
Now, I don't know how can show a progress bar without it defines in XML
file of activities? Are there any way to create a progress bar then add it
for showing or not?
Thanks
