How to solve a puzzle with dialogs, java android?

Question

Android

Create a chain of dialogues. On the main screen, create any
interface that is convenient for you. The main function of which is to open a dialog
(FragmentDialog). The dialog should have a field for entering a number, the
user can enter, or maybe not, and click "ok".
the next dialog with the same functionality will open, followed by the third
one. When the third dialog closes, the main screen should
reflect everything that the user has entered. If you did not enter anything,
then write about it.
I will be very grateful for the answer!! Please help me decide so that I can understand the examples well.
