Android fragmanlarını kullanarak paylaşılan öğe geçişlerini canlandırmak bir kabus gibi görünüyor

Question

İki fragman arasında paylaşılan bir eleman geçişini canlandırmak bir acı gibi görünüyor. Uygulamamdaki başka bir yerde tam olarak aynı kodla çalışıyorum. Sadece bu animasyon çalışması için görünmektedir olamaz

private void click(int position, ItemViewHolder holder){ 

final ItemDescription itemDescription = itemListFiltered.get(position); 
FragmentManager fm = mContext.getSupportFragmentManager(); 
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP && itemDescription != null) { 

    //animate transition 
    TransitionSet transitionSet = new TransitionSet(); 
    transitionSet.addTransition(new ChangeTransform()); 
    transitionSet.addTransition(new ChangeBounds()); 
    transitionSet.addTransition(new ChangeImageTransform()); 
    transitionSet.setDuration(300); 

    //set up fragment 
    ScanDetailsFragment frag = ScanDetailsFragment.newInstance(itemDescription, holder.productImage.getTransitionName()); 
    frag.setEnterTransition(transitionSet); 
    frag.setExitTransition(transitionSet); 

    fm.beginTransaction().replace(R.id.fragment_container, frag) 
      .addSharedElement(holder.productImage, "product_image") 
      .addToBackStack("item details") 
      .commit(); 
}else { 
    ScanDetailsFragment itemDetails = ScanDetailsFragment.newInstance(itemDescription); 
    fm.beginTransaction().replace(R.id.fragment_container, itemDetails).addToBackStack("item details").commit(); 
}

Ben RecyclerView

public class DogFragment extends Fragment implements DogAdapter.OnItemCLickListener { 

    public static final String TAG = "DogFragment"; 

    @InjectView(R.id.recyclerview_dog) 
    RecyclerView mRecyclerView; 

    DogAdapter adapter; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     super.onCreateView(inflater, container, savedInstanceState); 
     final View v = inflater.inflate(R.layout.fragment_dog, container, false); 
     ButterKnife.inject(this, v); 
     return v; 
    } 

    @Override 
    public void onActivityCreated(Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 

     final List<Integer> images = new ArrayList<>(); 
     images.add(R.drawable.dog1); 
     images.add(R.drawable.dog2); 
     images.add(R.drawable.dog3); 

     final RecyclerView.LayoutManager layoutManager = new GridLayoutManager(getActivity(), 1); 
     mRecyclerView.setLayoutManager(layoutManager); 
     adapter = new DogAdapter(images); 
     adapter.setOnItemClickListener(this); 
     mRecyclerView.setAdapter(adapter); 
    } 

    public String getTAG() { 
     return TAG; 
    } 

    @Override 
    public void onItemClick(int position, int imageRefId, ImageView imageView) { 
     SingleDogFragment fragment = SingleDogFragment.getInstance(getActivity(), adapter.getImageTransitionName(getActivity(), position), imageRefId); 
     getFragmentManager().beginTransaction() 
       .addSharedElement(imageView, adapter.getImageTransitionName(getActivity(), position)) 
       .replace(R.id.container, fragment, fragment.getTag()) 
       .addToBackStack(null) 
       .commit(); 
    } 
} 

adaptör

public class DogAdapter extends RecyclerView.Adapter<DogAdapter.ViewHolder> { 

    private OnItemCLickListener mItemClickListener; 
    private List<Integer> mImages; 

    public DogAdapter(List<Integer> images) { 
     mImages = images; 
    } 

    public int getItem(int position) { 
     return mImages.get(position); 
    } 

    @Override 
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) { 
     View v = LayoutInflater.from(viewGroup.getContext()) 
       .inflate(R.layout.gridview_element_dog, viewGroup, false); 

     return new ViewHolder(v); 
    } 

    @Override 
    public void onBindViewHolder(ViewHolder viewHolder, int i) { 
     viewHolder.mImageView.setImageResource(getItem(i)); 
     viewHolder.mImageView.setTransitionName(
       getImageTransitionName(viewHolder.mImageView.getContext(), i) 
     ); 
    } 

    public String getImageTransitionName(Context context, int position) { 
     return context.getString(R.string.dog_transition_name) + position; 
    } 

    @Override 
    public int getItemCount() { 
     return mImages.size(); 
    } 

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener { 

     @InjectView(R.id.dog_imageview) 
     ImageView mImageView; 

     public ViewHolder(final View view) { 
      super(view); 
      ButterKnife.inject(this, view); 
      view.setOnClickListener(this); 
     } 

     @Override 
     public void onClick(View v) { 
      if (mItemClickListener != null) { 
       mItemClickListener.onItemClick(getPosition(), getItem(getPosition()), mImageView); 
      } 
     } 
    } 

    public interface OnItemCLickListener { 
     public void onItemClick(int position, int refId, ImageView imageView); 
    } 

    public void setOnItemClickListener(final OnItemCLickListener mItemClickListener) { 
     this.mItemClickListener = mItemClickListener; 
    }

Fragment yaptım nasıl

public class SingleDogFragment extends Fragment { 

    private static final String ARG_TRANSITION_NAME = "ARG_TRANSITION_NAME"; 
    private static final String ARG_IMAGE_REF_ID = "ARG_IMAGE_REF_ID"; 

    @InjectView(R.id.single_dog_imageview) 
    ImageView mDogImage; 

    public static SingleDogFragment getInstance(Context context, String transitionName, int imageRefId) { 
     SingleDogFragment fragment = new SingleDogFragment(); 
     Bundle bundle = new Bundle(); 
     bundle.putString(ARG_TRANSITION_NAME, transitionName); 
     bundle.putInt(ARG_IMAGE_REF_ID, imageRefId); 
     fragment.setSharedElementEnterTransition(TransitionInflater.from(context).inflateTransition(R.transition.change_transform)); 
     fragment.setEnterTransition(TransitionInflater.from(context).inflateTransition(R.transition.slide_left)); 
     fragment.setExitTransition(TransitionInflater.from(context).inflateTransition(R.transition.slide_left)); 
     fragment.setArguments(bundle); 
     return fragment; 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
     super.onCreateView(inflater, container, savedInstanceState); 
     View v = inflater.inflate(R.layout.fragment_single_dog, container, false); 
     ButterKnife.inject(this, v); 
     mDogImage.setTransitionName(getArguments().getString(ARG_TRANSITION_NAME)); 
     mDogImage.setImageResource(getArguments().getInt(ARG_IMAGE_REF_ID)); 
     return v; 
    } 
} 

change_transform.xml

<?xml version="1.0" encoding="utf-8"?> 
<transitionSet xmlns:android="http://schemas.android.com/apk/res/android"> 
    <targets> 
     <target android:excludeId="@android:id/statusBarBackground"/> 
     <target android:excludeId="@android:id/navigationBarBackground"/> <!-- exclude the status bar and the navigation bar of the animation --> 
    </targets> 
    <changeBounds/> 
    <changeTransform/> 
</transitionSet>
