如何按行实现具有不同数量项的RecyclerView？

public class CustomLayoutManager extends RecyclerView.LayoutManager {
    private int rowCount = 3; // 每行的子项数量

    @Override
    public RecyclerView.LayoutParams generateDefaultLayoutParams() {
        return new RecyclerView.LayoutParams(
                RecyclerView.LayoutParams.WRAP_CONTENT,
                RecyclerView.LayoutParams.WRAP_CONTENT);
    }

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        detachAndScrapAttachedViews(recycler);

        int itemCount = getItemCount();
        if (itemCount == 0) {
            return;
        }

        int rowItemCount = itemCount / rowCount; // 每行的子项数量
        int remainItemCount = itemCount % rowCount; // 剩余的子项数量

        int offsetX = getPaddingLeft();
        int offsetY = getPaddingTop();

        for (int i = 0; i < rowCount; i++) {
            int currentRowCount = rowItemCount;
            if (i < remainItemCount) {
                currentRowCount++;
            }

            for (int j = 0; j < currentRowCount; j++) {
                View view = recycler.getViewForPosition(i * rowItemCount + j);
                addView(view);

                measureChildWithMargins(view, 0, 0);
                int width = getDecoratedMeasuredWidth(view);
                int height = getDecoratedMeasuredHeight(view);

                layoutDecorated(view, offsetX, offsetY, offsetX + width, offsetY + height);

                offsetX += width;
            }

            offsetX = getPaddingLeft();
            offsetY += getChildAt(i).getHeight();
        }
    }
}
