How to restart Activity after AlertDialog?

Question

Java

I have an Activity with information from a DB. By clicking on the button, an AlertDialog appears, where the data in the database changes, and I need to update the data on the Activity after exiting the dialog. How to do it?

Answer 1

Add a method that updates the data and when you click on the AlertDialog button or on the onCanceled listener ... call this method and don't even try to restart the Activity for this, this is a perversion

Answer 2

Data from the database, so you need to use a cursorloader.
After changing the data, it will load the changes itself and, if everything is done correctly, will display them.
