Supprimer un élément dans RecyclerView - Android

Je suis face à un problème, je ne pouvais pas supprimer un Élément dans RecyclerView.
Je suis en train de rechercher sur Internet, mais ne pouvait pas voir toute solution
Je suis à la suite de ce post
Android RecyclerView plus & suppression d'éléments
Mais je ne pouvais pas supprimer l'élément sélectionné
Ci-dessous mon code pour mon adaptateur et fragement

RecyclerViewAdapter.java

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {
List<VideoDetails> contents2;
Context mContext;
ImageLoader imageLoader;
static final int TYPE_HEADER = 0;
static final int TYPE_CELL = 1;
public RecyclerViewAdapter(List<VideoDetails> contents) {
this.contents2 = contents;
}
public RecyclerViewAdapter(Context context, List<VideoDetails> contents) {
mContext = context;
this.contents2 = contents;
imageLoader = new ImageLoader(context);
}
@Override
public int getItemViewType(int position) {
return position;
}
@Override
public int getItemCount() {
return contents2.size();
}
@Override
public RecyclerViewAdapter.ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
View view = null;
view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.list_item_card_small2, parent, false);
ViewHolder vh = new ViewHolder(view);
return vh;
}
@Override
public void onBindViewHolder(ViewHolder holder,final int position) {
holder.title.setText(contents2.get(position).getTitle());
holder.image.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
Log.d("thien.van","on Click onBindViewHolder");
contents2.remove(position);
notifyItemRemoved(position);
notifyItemRangeChanged(position, contents2.size());
}
});
}
public Bitmap getThumbnail(String str) {
Bitmap bMap = ThumbnailUtils.createVideoThumbnail(str, MediaStore.Video.Thumbnails.MINI_KIND);
return bMap;
}
public class ViewHolder extends RecyclerView.ViewHolder implements  View.OnClickListener {
public TextView title;
public ImageView image;
public ProgressBar progressBar;
public ViewHolder(View itemView) {
super(itemView);
title = (TextView) itemView.findViewById(R.id.title);
image = (ImageView) itemView.findViewById(R.id.thumbnail);
progressBar = (ProgressBar) itemView.findViewById(R.id.progress);
// image.setOnClickListener(this);
}
@Override
public void onClick(View view) {
Log.d("thien.van","onClick getAdapterPosition             () = "+getAdapterPosition());
removeAt(getAdapterPosition());
}
}
public void removeAt(int position) {
contents2.remove(position);
notifyDataSetChanged();
}

}

RecyclerViewFragment

public class RecyclerViewFragment extends Fragment {
private RecyclerView mRecyclerView;
private RecyclerView.Adapter mAdapter;
private static final int ITEM_COUNT = 2;
private List<Object> mContentItems = new ArrayList<>();
private static List<VideoDetails> mContentItems2 = new ArrayList<>();
public static RecyclerViewFragment newInstance() {
return new RecyclerViewFragment();
}
public static RecyclerViewFragment newInstance(List<VideoDetails> contentItems) {
RecyclerViewFragment myFragment = new RecyclerViewFragment();
// mContentItems = contentItems;
Bundle args = new Bundle();
args.putSerializable("thienvan", (Serializable) contentItems);
myFragment.setArguments(args);
return myFragment;
}
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
mContentItems2 = (List<VideoDetails>) getArguments().getSerializable("thienvan");
//Log.d("thien.van","Fragment file name = "+mContentItems2.get(0).getTitle());
return inflater.inflate(R.layout.fragment_recyclerview, container, false);
}
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView);
RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(getActivity());
mRecyclerView.setLayoutManager(layoutManager);
//mRecyclerView.setHasFixedSize(true);
mAdapter = new RecyclerViewMaterialAdapter(new RecyclerViewAdapter(getActivity().getBaseContext(),mContentItems2));
mRecyclerView.setAdapter(mAdapter);
/*{
for (int i = 0; i < ITEM_COUNT; ++i)
mContentItems.add(new Object());
mAdapter.notifyDataSetChanged();
}*/
MaterialViewPagerHelper.registerRecyclerView(getActivity(), mRecyclerView, null);
}

}

Je ne pouvais pas supprimer un élément à l'intérieur de l'Adaptateur de classe.
Quelqu'un pourrait-il m'aider ?
