Regarding ProperScrolling in Horizontal Recycler View

Question

I have issues scrolling in horizontal recycler view.For eg if i have 10 items,very first time,I am able to scroll till last item,But if i go to first item and then scroll again to last item,it is not moving to last item.

Is this issue related to scrolling,Should i override for scrolling,if that's case.

This is my fragment class declaration

      LinearLayoutManager layoutManager
            = new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false);
    mRecyclerView = (RecyclerView)v. findViewById(R.id.recycler_view);
    adapter  = new MyRecyclerAdapter(getActivity());
    mRecyclerView.setLayoutManager(layoutManager);
    mRecyclerView.setAdapter(adapter);

and in my adapter

public class MyRecyclerAdapter extends RecyclerView.Adapter<MyRecyclerAdapter.CustomViewHolder> {

private Context mContext;
JobSiteActivity mjobSiteActivity;
ImageLoader loader = null;

public MyRecyclerAdapter(Activity activity) {
    this.mContext = activity;
    mjobSiteActivity = (JobSiteActivity)activity;
    loader = mjobSiteActivity.getImageLoader();
}

@Override
public CustomViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.image_detail_fragment, null);

    CustomViewHolder viewHolder = new CustomViewHolder(view);
    return viewHolder;
}

@Override
public void onBindViewHolder(CustomViewHolder customViewHolder, int i) {
    //FeedItem feedItem = feedItemList.get(i);

    //Download image using picasso library
  /*  Picasso.with(mContext).load(feedItem.getThumbnail())
            .error(R.drawable.placeholder)
            .placeholder(R.drawable.placeholder)
            .into(customViewHolder.imageView);*/

    customViewHolder.imageView.setImageUrl(Images.imageThumbUrls[i], loader);
    customViewHolder.imageView.setOnClickListener(clickListener);
    customViewHolder.imageView.setTag(customViewHolder);


    //Setting text view title

}

@Override
public int getItemCount() {
    //return (null != feedItemList ? feedItemList.size() : 0);
    return  Images.imageThumbUrls.length;
}

public class CustomViewHolder extends RecyclerView.ViewHolder {
    protected NetworkImageView imageView;


    public CustomViewHolder(View view) {
        super(view);
        this.imageView = (NetworkImageView) view.findViewById(R.id.imageView);

    }
}


View.OnClickListener clickListener = new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        CustomViewHolder holder = (CustomViewHolder) view.getTag();
        int position = holder.getLayoutPosition();
        int position1 = holder.getAdapterPosition();
        Toast.makeText(mContext, "layoutPs"+position+"adapPos"+position, Toast.LENGTH_SHORT).show();
    }
};

}

I am trying to use horizontal Grid view which comes with V17 leanback which also extends recycleView,but Still I am also facing similar sort of issue,

If i try to add any item to recycler view at runtime for eg on taking Photo,it is also not getting added,It allocates space and it is empty?Very hard to understand or debug on this issue.

Try to use layoutManager like this, may help you

LinearLayoutManager layoutManager=new LinearLayoutManager(getApplicationContext(),LinearLayoutManager.HORIZONTAL,false);
