问题
I wanted to know if there is any way to use shared elements between an activity/fragment and a dialog?
I have a project which contains dialogs and I want to make a transition between an ImageView in Activity's view hierarchy to the relevant ImageView in my GalleryDialog.
I searched a bit and found this link:
Shared element transition with Dialog Activity
which describes the workflow for using dialog themed activity. I was wondering if I could do it without using an extra activity and passing data with intent to that activity.

AFAIK its impossible to use shared elements between a fragment/activity and a dialog. The best way implement this is the link you mentioned, using a dialog-themed activity that looks like a dialog and send data via intent to the acctivity.
For sending large data with intent, you can either use parcelables or an external place to store data, e.g. a singleton class or a database. Have a look at the following answer regarding transferring large data between activities:
