49.4 Customizing the Transition

The final task in this example is to modify the changeBounds transition so that it is performed over a longer duration and incorporates a bounce effect when the view reaches its new screen location. This involves the creation of a Transition instance with appropriate duration interpolator settings which is, in turn, passed through as an argument to the beginDelayedTransition() method:

.

.

import android.transition.ChangeBounds

import android.transition.Transition

import android.view.animation.BounceInterpolator

.

.

private fun handleTouch() {

 

    val changeBounds: Transition = ChangeBounds()

    changeBounds.duration = 3000

    changeBounds.interpolator = BounceInterpolator()

 

    TransitionManager.beginDelayedTransition(myLayout, changeBounds)

 

    myButton.minWidth = 500

  ...
