Adding to sonnv1368's answer :

Try this :

Create a boolean in your model class object to keep track of selection of imageview : say boolean isSelected;

@Override
public void onBindViewHolder(final RecyclerView.ViewHolder holder, int position) {
    Object item = objectList.get(position);
    holder.imageView.setSelected(item.getSelected());

}

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

    ImageView imageView;
    public ViewHolder(View view) {
      //initialization code here
      imageView.setOnClickListener(this);
    }

    @Override
    public void onClick( View view ) {
      Object object = objectList.get(getAdapterPosition());
      object.isSelected() ? object.setSelected(false) : object.setSelected(true);
      notifyItemChanged(getAdapterPosition());
    }
}
