In my app i have a class called tasti.class where i have a simple layout with a ScrollView and some CardView's in it.
It also has a button and when i press it it's open a custom AlertDialog so my question is how could i add other CardViews after i insert in my custom AlertDialog the name to place in the TextView of the CardView and the "Prezzo" that it should be a description of the textView i mean by pressing the button "AGGIUNGI" how could i create a new CardView and add it to the bottom of the ScrollView?
Here is my XML code of the layout part:
