如何在Android的网格视图中设置自定义纵横比？

public class CustomGridAdapter extends BaseAdapter {
    private Context mContext;
    private List<GridItem> mGridItems;

    public CustomGridAdapter(Context context, List<GridItem> gridItems) {
        mContext = context;
        mGridItems = gridItems;
    }

    @Override
    public int getCount() {
        return mGridItems.size();
    }

    @Override
    public Object getItem(int position) {
        return mGridItems.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            LayoutInflater inflater = LayoutInflater.from(mContext);
            convertView = inflater.inflate(R.layout.grid_item_layout, parent, false);
        }

        // 设置自定义纵横比
        int screenWidth = mContext.getResources().getDisplayMetrics().widthPixels;
        int gridItemWidth = screenWidth / NUM_COLUMNS; // NUM_COLUMNS为每行网格项的数量
        int gridItemHeight = (int) (gridItemWidth * ASPECT_RATIO); // ASPECT_RATIO为自定义的纵横比
        convertView.setLayoutParams(new GridView.LayoutParams(gridItemWidth, gridItemHeight));

        // 设置其他视图内容
        ImageView imageView = convertView.findViewById(R.id.image_view);
        TextView textView = convertView.findViewById(R.id.text_view);
        GridItem gridItem = mGridItems.get(position);
        imageView.setImageResource(gridItem.getImageResId());
        textView.setText(gridItem.getText());

        return convertView;
    }
}
