[Chip] Chip doesn't expand with animation when checked

Description: When I check a Chip in a ChipGroup the animation does not work properly.

Expected behavior:

Source code: stateChipGroup.setOnCheckedChangeListener { group, checkedId -> if (checkedId == View.NO_ID) { //user tried to uncheck the checked button group.check(lastCheckedId) return@setOnCheckedChangeListener } lastCheckedId = checkedId val chip = stateChipGroup.findViewById<View?>(checkedId) if (chip != null && chip is Chip) { when (chip.text) { getString(R.string.enabled) -> { sharedPref?.edit { putInt(CHIP_KEY_STATE, BEACON_VISIBLE) commit() } } getString(R.string.disabled) -> { sharedPref?.edit { putInt(CHIP_KEY_STATE, BEACON_INVISIBLE) commit() } } getString(R.string.both) -> { sharedPref?.edit { putInt(CHIP_KEY_STATE, BEACON_BOTH) commit() } } } vm.updateRecyclerView() } }

Hey,

I’ll re-open this issue for the animation. We have no plans to change this animation anytime soon even though we agree that it doesn’t look as smooth as the design site’s version.

The lack of animation is jarring. It isn’t as described in the material design documentation
