Is it possible to add a full screen dialog according to the material design guides?

Question

Android

The guides say that in some cases, dialogues for mobile phones can be done in full screen mode. I've searched the manuals but haven't found any way to implement this using a DialogFargment other than putting it in an Activity. Is this the correct way or is there a better solution?

Answer 1

The method of implementation depends on the needs (read "design") in a particular case.
In general, a full-screen dialog is essentially a regular activity with the appropriate design.
I have a screen in one of my apps that should be a regular dialog on big devices (tablets) and full screen on small ones (smartphones). For such a case, we create an activity and give it a theme inherited from Theme.AppCompat.DialogWhenLarge . Everything, it remains only to change the design of the activity as needed, setting the theme attributes.
