Is it possible to disable MotionLayout?

Now with ConstraintLayout beta 2 you can! This is the official way to do it:

motionLayout.getTransition(R.id.yourTransition).setEnable(false)

Recently I've been hacking around MotionLayout a lot, so far I found my trick to disable Motionlayout is like below.

layoutContainer.setTransitionListener(object: MotionLayout.TransitionListener {
        override fun onTransitionTrigger(p0: MotionLayout?, p1: Int, p2: Boolean, p3: Float) {}
        override fun onTransitionStarted(p0: MotionLayout?, p1: Int, p2: Int) {}
        override fun onTransitionCompleted(p0: MotionLayout?, p1: Int) {}
        override fun onTransitionChange(p0: MotionLayout?, startedScene: Int, endScene: Int, p3: Float) {
            when(currentFragmentTag) {
                TAG_DEFAULTBACKGROUND ->  {
                    if( startedScene==R.id.halfExpanded ) {
                        layoutContainer.transitionToState(startedScene)
                    }
                }
            }
        }
    })

So basically, I'm telling to MotionLayout to go back on certain situations. I feel like onTransitionTrigger or onTransitionStarted should contain the stopping function but it won't listen at those moments.

onTransitionChange is where it actually starts moving. I think you'll get the point of this trick vice versa.

Happy coding!

I found a handy solution to temporarily disable motion layout transtion. Set this to your MotionLayout in xml :

app:interactionEnabled="false"

The advantage of the solution is using it directly in an xml file, which gives you the option of connecting to data binding

app:interactionEnabled="@{viewModel.shouldInteractionBeActive}"

Its working out of box without any additional binding adapters. This was added in constraintlayout:2.1.0-beta01.

Actually, i managed to get it working by setting the start state of my scene for both start and end. In kotlin:

motionLayout.setTransition(R.id.start, R.id.start)

And when i needed to enable my layout:

motionLayout.setTransition(R.id.start, R.id.end)

No need to change your scene xml, worked flawlessly for me in alpha-03
