Shared element transition in RecyclerView

Question

I am trying to use shared element transition on RecyclerView but it doesn\'t seem to work.

This is a part of my adapter in which I use makeSceneTransitionAnimation

Answer 1

In your Adapter

holder.smallThumbnail.setTransitionName("thumbnailTransition");
Pair pair1 = Pair.create((View) holder.smallThumbnail, holder.smallThumbnail.getTransitionName());

ActivityOptionsCompat optionsCompat = ActivityOptionsCompat.makeSceneTransitionAnimation((Activity) mContext, pair1, pair2);
mContext.startActivity(intent, optionsCompat.toBundle());

In Your Detail Activity

getWindow().setSharedElementEnterTransition(TransitionInflater.from(this).inflateTransition(R.transition.shared_element_transation));
mainImage.setTransitionName("thumbnailTransition");

Here this mainimage is imageview where you want to transform your previous activity thumbnail

shared_element_transation create one xml in res>transition
