Tengo una vista de reciclador con las imágenes cargadas desde el almacenamiento interno. Quiero resaltar el elemento seleccionado al hacer clic. Intenté muchas cosas pero no funcionó. En realidad, lo que necesito es cuando hago clic en cualquier elemento en la Vista de Reciclador, ese Elemento debe ir a Mi Lista de Arreglos y también debe resaltarse y nuevamente cuando hago clic o digo no seleccionar, debe volver a ser normal. Aquí está mi código:

public class Images extends Fragment {
    private List<ImageHolder> imageList;
    Cursor imageCursor;

    RecyclerView recyclerView;
    MyImageAdapter adapter;
    ActionButton clickButton;
    List<String> listofImages;
    List<Integer> pos;
    int columnIndex;
    StringBuilder stringBuilder;
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,   Bundle savedInstanceState) {
        View rootlayout = inflater.inflate(R.layout.image, container, false);
        listofImages=new ArrayList<String>();
        pos=new ArrayList<Integer>();
        stringBuilder=new StringBuilder();
        ContentResolver imageResolver = getActivity().getContentResolver();
        Uri imageUri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
        String projection[]={MediaStore.Images.Thumbnails._ID,MediaStore.Images.Media.TITLE};
        imageCursor = getActivity().managedQuery(imageUri, projection, null, null, null);

        clickButton= (ActionButton) rootlayout.findViewById(R.id.action_button);

        recyclerView = (RecyclerView) rootlayout.findViewById(R.id.recycler_view_image);
        adapter = new MyImageAdapter(getActivity(), getImageList());

        recyclerView.setAdapter(adapter);
        recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

        recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getActivity(),recyclerView,new RecyclerTouchListener.ClickListener() {
            @Override
            public void onClick(View view, int position) {
               TextView tv= (TextView) view.findViewById(R.id.list_text_all);
                    int flag=0;

                    String[] projection = {MediaStore.Images.Media.DATA};
                    imageCursor = getActivity().managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                            projection, 
                            null,       
                            null,
                            null);
                    columnIndex = imageCursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
                    imageCursor.moveToPosition(position);
                    // Get image filename
                    String imagePath = imageCursor.getString(columnIndex);
                    if (listofImages.contains(imagePath)){
                        Log.d("Contains Test","Yes");
                        listofImages.remove(imagePath);
                        pos.remove(position);
                    } else {
                        listofImages.add(imagePath);
                        pos.add(position);
                        Log.d("Contains Test","No");
                    }

                String s=listofImages.size()+" "+imagePath;
                Log.d("Inserted",s);
            }

            @Override
            public void onLongClick(View view, int position) {}
        }));

        clickButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                for (int i=0;i<listofImages.size();i++){
                    stringBuilder.append(listofImages.get(i)+"\n");
                }
                Toast.makeText(getActivity(),stringBuilder,Toast.LENGTH_LONG).show();
            }
        });

        return rootlayout;
    }

    public List<ImageHolder> getImageList() {
        imageList=new ArrayList<ImageHolder>();

        if(imageCursor!=null && imageCursor.moveToFirst()){

           int titleColumn = imageCursor.getColumnIndex
                    (android.provider.MediaStore.Images.Media.TITLE);
            int idColumn = imageCursor.getColumnIndex
                    (android.provider.MediaStore.Images.Media._ID);

            do {
                ImageHolder img=new ImageHolder();
                img.id=imageCursor.getLong(idColumn);
                img.title=imageCursor.getString(titleColumn);

                img.iconid= imageCursor.getInt(idColumn);


                imageList.add(img);
            }
    ,        while (imageCursor.moveToNext());
        }

        return  imageList;
    }
}

Esta es mi clase de adaptador:

public class MyImageAdapter extends RecyclerView.Adapter<MyImageAdapter.MyViewHolder> {
    Context context;
    private LayoutInflater inflater;
    List<ImageHolder> data= Collections.emptyList();
    private ClickListener clickListener;
    int width,height;

    public MyImageAdapter(Context context, List<ImageHolder> data1) {
        inflater = LayoutInflater.from(context);
        this.data=data1;
        this.context=context;
    }

    @Override
    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = inflater.inflate(R.layout.all_row, parent, false);
        MyViewHolder holder=new MyViewHolder(view);
        return holder;
    }

    @Override
    public void onBindViewHolder(MyViewHolder holder, int position) {
        try{
            ImageHolder current=data.get(position);
            holder.title.setText(current.title);

            Log.d("Imageid:"+current.iconid,"");
            Uri IMAGE_URI = Uri.withAppendedPath(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, "" + current.iconid);

            Bitmap bitmap = Bitmap.createScaledBitmap(decodeUri(IMAGE_URI), 200, 200, true);
            holder.img.setImageBitmap(bitmap);
        }
        catch(Exception e){}
    }
    public void deleteRecyclerData(int position){
        data.remove(position);
        notifyItemRemoved(position);
    }


    private Bitmap decodeUri(Uri selectedImage) throws FileNotFoundException {
        BitmapFactory.Options o = new BitmapFactory.Options();
        o.inJustDecodeBounds = true;
        BitmapFactory.decodeStream(
               context.getContentResolver().openInputStream(selectedImage), null, o);

        final int REQUIRED_SIZE = 100;

        int width_tmp = o.outWidth, height_tmp = o.outHeight;
        int scale = 1;
        while (true) {
            if (width_tmp / 2 < REQUIRED_SIZE || height_tmp / 2 < REQUIRED_SIZE) {
                break;
            }
            width_tmp /= 2;
            height_tmp /= 2;
            scale *= 2;
        }

        BitmapFactory.Options o2 = new BitmapFactory.Options();
        o2.inSampleSize = scale;
        return BitmapFactory.decodeStream(
                context.getContentResolver().openInputStream(selectedImage), null, o2);
    }
    @Override
    public int getItemCount() {
        return data.size();
    }

    public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{
        TextView title;
      // TextView artist;
        ImageView img;
        CheckBox checkBox;

        public MyViewHolder(View itemView) {
            super(itemView);
            title= (TextView) itemView.findViewById(R.id.list_text_all);
            img= (ImageView) itemView.findViewById(R.id.list_image_all);
            img.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {}
    }
    public interface ClickListener{
        public void itemClicked(View view, int position);
    }
}
