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

[JonathanImperato]

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() } }

I can't see or discern what about the animation is incorrect except that it looks a bit fast. Please write more about what you expect from the animation.

The line break / change is expected behavior.

I am not referring to the line break change but to the animation lag. In the first gif you see that when the checkmark appears (from the left to the right) the text slide to the right and again when disappears the text slide to the left. Both are animating, the checkmark and the text. This is not happening in my project.

Any suggestion? @ldjcmu

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.

is there any update on this?

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