1.0.4

Released version 1.0.4.

What's the difference?

We can transform a view or fragment into a fragment.

How to use?

Here is some example of transformation RecyclerView item in Fragment A into Fragment B.

FragmentA

override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    // [Step1]: apply onTransformationStartContainer.
    onTransformationStartContainer()
}

  /** This function will be called from the [PosterSingleAdapter.PosterDelegate]'s onBindViewHolder. */
  override fun onItemClick(poster: Poster, itemView: TransformationLayout) {
    val fragment = MainSingleDetailFragment()
    // [Step2]: getBundle from the TransformationLayout.
    val bundle = itemView.getBundle(MainSingleDetailFragment.paramsKey)
    bundle.putParcelable(MainSingleDetailFragment.posterKey, poster)
    fragment.arguments = bundle

    requireFragmentManager()
      .beginTransaction()
      // [Step3]: addTransformation using the TransformationLayout.
      .addTransformation(itemView)
      .replace(R.id.main_container, fragment, MainSingleDetailFragment.TAG)
      .addToBackStack(MainSingleDetailFragment.TAG)
      .commit()
  }

RecyclerView.Adapter

transformationLayout.transitionName = item.name

If you want to transform view (not a recyclerView's item), set transiton name in on onViewCreated.

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
    transformationLayout.transitionName = item.name
}

FragmentB

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

    // [Step1]: apply onTransformationEndContainer using TransformationLayout.Params.
    val params = arguments?.getParcelable<TransformationLayout.Params>(paramsKey)
    onTransformationEndContainer(params)
  }

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
    super.onViewCreated(view, savedInstanceState)
   
    // [Step2]: sets a transition name to the target view.
    detail_container.transitionName = poster.name
}
