android - 在 NavigationView 中居中 MaterialCardView

Question

我试图将卡片视图集中在导航视图中，但它只是不想工作。在设计器中它看起来不错，但是当我在模拟器中运行它时它只是粘在左边。

卡片视图：

/*

public class MenuCardAdapter extends RecyclerView.Adapter<MenuCardAdapter.Viewholder> {
    private Context context;
    private ArrayList<MenuCardBencinskaCrpalka> menuCardsArrayList;

    // Constructor
    public MenuCardAdapter(Context context, ArrayList<MenuCardBencinskaCrpalka> menuCardsArrayList) {
        this.context = context;
        this.menuCardsArrayList = menuCardsArrayList;
    }
    
    @NonNull
    @Override
    public MenuCardAdapter.Viewholder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        // to inflate the layout for each item of recycler view.
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.menu_card_layout, parent, false);
        return new Viewholder(view);
    }

        //model je objekt razreda MenuCardBencinskaCrpalka
        holder.logo.setImageResource(model.getLogoImageID());
        holder.naslov.setText(model.getNaslov());
        holder.naziv.setText(model.getNaziv());
//        holder.gorivoLayout = model.getGorivoLayout();

        //Toast.makeText(holder.logo.getContext(), holder.naziv.getText(), Toast.LENGTH_SHORT).show();

    }

    @Override
    public int getItemCount() {
        // this method is used for showing number
        // of card items in recycler view.
        return menuCardsArrayList.size();
    }

    // View holder class for initializing of
    // your views such as TextView and Imageview.
    public class Viewholder extends RecyclerView.ViewHolder {

        public View view; //trenutni CardView
        public ImageView logo;
        public TextView naziv, naslov;
        public LinearLayout gorivoLayout;

        public Viewholder(@NonNull View itemView) {
            super(itemView);

            logo = itemView.findViewById(R.id.logo);
            naziv = itemView.findViewById(R.id.naziv);
            naslov = itemView.findViewById(R.id.naslov);
            //gorivoLayout = itemView.findViewById(R.id.gorivoLayout);

            //Toast.makeText(itemView.getContext(), "test", Toast.LENGTH_SHORT).show();

            view = itemView;
            view.setOnClickListener(new View.OnClickListener() {
                @Override public void onClick(View v) {
                    // item clicked

                    //Toast.makeText(v.getContext(), "clicked", Toast.LENGTH_SHORT).show();
                }
            });
        }
    }
}

结果总是这样，除非我手动添加填充

在设计器 UI 中，它看起来不错

有任何想法吗？
