Just quoting the Android Docs [LINK] : Start an activity with a shared element Assign a common name to the shared elements in both layouts with the android:transitionName attribute. From what I see, both of your XMLs don't share the same android:transitionName . Try changing both android:transitionName in the XML layout (activity_main.xml & dialog_sheet.xml) to a same string, for example: transition_plane_feather I havent't tested the codes myself, but I think that might be a good starting point. Bonus Tip If you're planning to fully implement Material Design without compatibility with lower API levels (pre-Lollipop), I highly recommend checking out a sample made by a Google UI/UX Designer:

i'm working on a RecyclerView in Android which should contains expandable cards. I've already seen some questions like this [LINK] or this [LINK] but I can't figure out how to manage some things.

I've followed Nick Butcher's Material Improvements I/O 2016 talk [this video] , and at about 6:00, he starts talking about animating list items. I've implemented the feature exactly as he was doing it, and the bound changes animate correctly, but color changes don't animate, despite him explicitly saying they would: [LINK] This is what the code looks like: This is the relevant part of the RecyclerView.Adapter class: override fun onBindViewHolder(holder: ViewHolder, position: Int) { val item: Pair<String, String> = items[position] holder.title.text = item.first holder.subtitle.text = item.second val isExpanded = position == expandedPosition holder.subtitle.visibility = if (isExpanded) View.VISIBLE
