使用默认的ListRowPresenter会出现边距问题，如下：

只要能获取id为row_content的HorizontalGridView就可以修改，效果如下

需要修改行的样式即可

@Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);

        ArrayObjectAdapter rowAdapter = new ArrayObjectAdapter(new ListRowPresenter(){
            @Override
            protected RowPresenter.ViewHolder createRowViewHolder(ViewGroup parent) {
                //获取grdiview修改
                ListRowView rowView = new ListRowView(parent.getContext());
                rowView.getGridView().setPadding(0,0,0,0);
                LinearLayout.LayoutParams lp = (LinearLayout.LayoutParams) rowView.getGridView().getLayoutParams();
                lp.topMargin = 0;
                lp.bottomMargin = 0;
                lp.leftMargin = 0;
                lp.rightMargin = 0;
                rowView.getGridView().setLayoutParams(lp);
                return new ViewHolder(rowView, rowView.getGridView(), this);
            }
        });

        for (int i = 0; i < 5; i++) {
            ArrayObjectAdapter cardAdapter = new ArrayObjectAdapter(new HomePresenter());
            cardAdapter.add(i+"-aaa");
            cardAdapter.add(i+"-bbb");
            cardAdapter.add(i+"-ccc");
            rowAdapter.add(new ListRow(cardAdapter));
        }


        setAdapter(rowAdapter);
    }
