I am trying to implement the following concept.

When user click on the addButton. Then there should open a window and display message

Please enter new Element

After entering the element must be added into the list.

My problem is that how can I please implement the concept of window displaying dialogue "Please ent new Element."

Thanks

the most simple way:
create a screen that gets a callback in its constructor (a reference on your origin screen). push the new screen and ask the user to enter something there (using an editfield, e.g.). after clicking a submit-button the calls the callback and pops itself.

a bit more advanced would be to use a popup screen, a more distinctive enter method compared to a submit-button and the use of an interface as a callback.

Yes pop-up a new screen
