Transition from Activity to Fragment

Question

How to create a transition from an Activity to a Fragment?

I specificly tried to create a MaterialSharedAxis transition from an Activity to a Fragment which did not work for me.

Sample Code:

// Activity A

val fragment = Fragment1()
fragment.enterTransition = MaterialSharedAxis(MaterialSharedAxis.X, true)
fragment.exitTransition = MaterialSharedAxis(MaterialSharedAxis.X, false)

val fragmentManager = supportFragmentManager
    .beginTransaction()
    .add(R.id.fragment_container_view, Fragment1())
    .addToBackStack("fragment")
    .commit()

// Fragment B

class Fragment1 : Fragment() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        enterTransition = MaterialSharedAxis(MaterialSharedAxis.X, true)
        returnTransition = MaterialSharedAxis(MaterialSharedAxis.X, false)
    }

    ...
}
