How to use TimePickerDialog and DarePickerDialog?

Question

Java

It is necessary to show the notification at the date and time selected by the user in the dialog.
There is a code, but it does not work as it should. I select tomorrow's date and time in the dialog one minute ahead of the current one (for example, 12:20) and the notification arrives in a minute, although it should come tomorrow ... I select today's day in the dialog and the notification immediately appears, I don’t even have time to set the time ..
Somehow the date and time are processed separately, but it is necessary that this whole be ...
