How to use LottieAnimationView in SharedElementTransition? - kotlin

Question

I decided to use Lottie animation to switch from activity to activity.
My animation covers the entire screen, and I would like to have half the animation time played on the first activity and the rest on the second activity
I tried using Shared Element Transition but it doesn't work properly because when new activity starts first what i see is new activity and then after few miliseconds Lottie animation resumes. I would like to avoid showing new activity before Lottie animation is over
First Activity XML file
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<com.airbnb.lottie.LottieAnimationView android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/newActivityAnimation"
app:lottie_fileName="transitionAnimation.json"
android:scaleType="centerCrop"
android:elevation="5dp"
android:transitionName="sharedNewActivityTransition"
/>
Second Activity XML file
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.MenuActivity">
<com.airbnb.lottie.LottieAnimationView android:layout_width="match_parent"
android:layout_height="match_parent"
app:lottie_fileName="transitionAnimation.json"
android:scaleType="centerCrop"
android:id="#+id/changeActivityAnimationMenu"
android:elevation="5dp"
android:transitionName="sharedNewActivityTransition"
/>
</RelativeLayout>
Here is function which start changing activite
override fun onLanguageClickListener(position: Int) {
animateCollapseMenuSlide(isMenuCollapsed)
newActivityAnimation.setMaxFrame(19)
delay.delayedFunction({newActivityAnimation.playAnimation()},200)
delay.delayedFunction({changeActivity()},1000)
}
.
.
.
private fun changeActivity() {
val intent = Intent(this,MenuActivity::class.java)
intent.flags = Intent.FLAG_ACTIVITY_NO_ANIMATION
val options = ActivityOptionsCompat.makeSceneTransitionAnimation(this,activityTransitionAnimation,
"sharedNewActivityTransition")
startActivity(intent,options.toBundle())
}
