Following four steps with RecyclerView - CardView - ImageView: a. fade in imageview in onBind: calling imageView.setTransientState(true) b. RecyclerView animate the item: calling cardView.setTransientState(true) c. fade-in finishes, calling imageView.setTransientState(false) d. RecyclerView animation finishes: calling cardView.setTransientState(false) After these four steps, RecyclerView unexpectedly has transient state. The problem is in step b, when calling cardView.setTransientState() it incorrectly calls parent.childHasTransientStateChanged(this, true) which causes RecyclerView's mChildCountWithTransientState increased to 2. And it's decreased to 1 in step d and stay as 1 forever. The child should only call childHasTransientStateChanged() when actual hasTransientState() changed.
