Android horizontal recycleview fill screen on landscape

Question

I got a horizontal recycleview. It shows a list of elements. My problem is that it looks bad on large screens and landscape modes. Here looks ok. On landscape looks bad, here is screenshot. How to fix to like in first screenshot ??

HomeFragment.class

RecyclerView recyclerView = (RecyclerView) rootView.findViewById(R.id.my_recycler_view);
        recyclerView.setHasFixedSize(true);
        HorizontalRecycleViewAdapter adapter = new HorizontalRecycleViewAdapter(getActivity(), categoriesList);
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity(), LinearLayoutManager.HORIZONTAL, false));
        recyclerView.setNestedScrollingEnabled(false);
        recyclerView.setAdapter(adapter);

fragment_home.xml

  <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusable="true"
        android:focusableInTouchMode="true">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/my_recycler_view"
            android:layout_width="match_parent"
            android:layout_height="200dp"
            android:scrollbars="none" />
    </LinearLayout>

HorizontalRecycleViewAdapter.class

public class HorizontalRecycleViewAdapter extends RecyclerView.Adapter<HorizontalRecycleViewAdapter.SingleItemRowHolder> {

    private ArrayList<Category> itemsList;
    private Context mContext;

    public HorizontalRecycleViewAdapter(Context context, ArrayList<Category> itemsList) {
        this.itemsList = itemsList;
        this.mContext = context;
    }

    @Override
    public SingleItemRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_single_card, null);
        SingleItemRowHolder mh = new SingleItemRowHolder(v);
        return mh;
    }

    @Override
    public void onBindViewHolder(SingleItemRowHolder holder, int i) {
        Category item = itemsList.get(i);
        holder.title.setText(item.getName());
        holder.imageResource.setImageResource(item.getImageSource());
    }

    @Override
    public int getItemCount() {
        return (null != itemsList ? itemsList.size() : 0);
    }

    public class SingleItemRowHolder extends RecyclerView.ViewHolder {

        protected TextView title;
        protected ImageView imageResource;
        public SingleItemRowHolder(View view) {
            super(view);
            this.title = (TextView) view.findViewById(R.id.tvTitle);
            this.imageResource = (ImageView) view.findViewById(R.id.itemImage);
            view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Toast.makeText(v.getContext(), title.getText(), Toast.LENGTH_SHORT).show();
                }
            });
        }
    }
}

Modified as @Onur Çevik said with layoutparams of ImageView

Here is the code:

HorizontalRecycleViewAdapter.class

 @Override
    public void onBindViewHolder(SingleItemRowHolder holder, int i) {


        Category item = itemsList.get(i);
        holder.title.setText(item.getName());

        holder.imageResource.setImageResource(item.getImageSource());
        if (Utils.getScreenOrientation((Activity) mContext) == 2) {
            holder.imageResource.getLayoutParams().width = Utils.getScreenWidth((Activity) mContext) / getItemCount();
        }

    }

Utils.class

public class Utils{
 public static int getScreenOrientation(Activity activity) {
        Display getOrient = activity.getWindowManager().getDefaultDisplay();
        int orientation = Configuration.ORIENTATION_UNDEFINED;
        if (getOrient.getWidth() == getOrient.getHeight()) {
            orientation = Configuration.ORIENTATION_SQUARE;
        } else {
            if (getOrient.getWidth() < getOrient.getHeight()) {
                orientation = Configuration.ORIENTATION_PORTRAIT;
            } else {
                orientation = Configuration.ORIENTATION_LANDSCAPE;
            }
        }
        return orientation;
    }

    public static int getScreenWidth(Activity activity) {
        Display display =  activity.getWindowManager().getDefaultDisplay();
        return display.getWidth();
    }
}
