如何使RecyclerView中的卡片在不同的DPI中成为正方形

public class SquareCardAdapter extends RecyclerView.Adapter<SquareCardAdapter.ViewHolder> {
    private Context mContext;
    private int mScreenWidth;
    private int mCardSize;

    public SquareCardAdapter(Context context) {
        mContext = context;
        DisplayMetrics displayMetrics = mContext.getResources().getDisplayMetrics();
        mScreenWidth = displayMetrics.widthPixels;
        mCardSize = mScreenWidth / 2; // 每行显示2个卡片，所以卡片宽度为屏幕宽度的一半
    }

    @NonNull
    @Override
    public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(mContext).inflate(R.layout.item_card, parent, false);
        return new ViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
        holder.bind();
    }

    @Override
    public int getItemCount() {
        return 10; // 假设有10个卡片
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        private View mCardView;

        public ViewHolder(@NonNull View itemView) {
            super(itemView);
            mCardView = itemView.findViewById(R.id.card_view);
        }

        public void bind() {
            ViewGroup.LayoutParams layoutParams = mCardView.getLayoutParams();
            layoutParams.width = mCardSize;
            layoutParams.height = mCardSize;
            mCardView.setLayoutParams(layoutParams);
        }
    }

    public class CardItemDecoration extends RecyclerView.ItemDecoration {
        private int mSpacing;

        public CardItemDecoration(Context context) {
            mSpacing = context.getResources().getDimensionPixelSize(R.dimen.card_spacing);
        }

        @Override
        public void getItemOffsets(@NonNull Rect outRect, @NonNull View view, @NonNull RecyclerView parent, @NonNull RecyclerView.State state) {
            outRect.set(mSpacing, mSpacing, mSpacing, mSpacing);
        }
    }
}
