How to use shared element transitions in Navigation Controller
I would like to add a shared elements transition using the navigation architecture components, when navigating to an other fragment. But I have no idea how. Also in the documentations there is nothing about it. Can someone help me?
FirstFragment
val extras = FragmentNavigatorExtras(
imageView to "secondTransitionName")
view.findNavController().navigate(R.id.confirmationAction,
null, // Bundle of args
null, // NavOptions
extras)
first_fragment.xml
<ImageView
android:id="@+id/imageView"
android:transitionName="firstTransitionName"
...
/>
SecondFragment
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?): View {
sharedElementEnterTransition = ChangeBounds().apply {
duration = 750
}
sharedElementReturnTransition= ChangeBounds().apply {
duration = 750
}
return inflater.inflate(R.layout.second_fragment, container, false)
}
second_fragment.xml
<ImageView
android:transitionName="secondTransitionName"
...
/>
I tested it. It is worked.
I took reference from this github sample https://github.com/serbelga/android_navigation_shared_elements
cardView.setOnClickListener{
val extras = FragmentNavigatorExtras(
imageView to "imageView"
)
findNavController().navigate(R.id.detailAction, null, null, extras)
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
sharedElementEnterTransition = TransitionInflater.from(context).inflateTransition(android.R.transition.move)
It is working properly.
Since 1.0.0-alpha06 the navigation component supports adding shared element transitions between destinations. Just add FragmentNavigatorExtras to navigate() call. More details: https://developer.android.com/guide/navigation/navigation-animate-transitions#shared-element
val extras = FragmentNavigatorExtras(
imageView to "header_image",
titleView to "header_title")
view.findNavController().navigate(R.id.confirmationAction,
null, // Bundle of args
null, // NavOptions
extras)
