如何将边距开始添加到DividerItemDecoration Android

我使用下面的代码将分隔符添加到我的列表中。但我的问题是，如何在这些分割线上添加边距，使其看起来像所附的图像。先谢谢你

DividerItemDecoration dividerItemDecoration = new DividerItemDecoration(recyclerView.getContext(),
    layoutManager.getOrientation());
recyclerView.addItemDecoration(dividerItemDecoration);

您需要重写方法

getItemOffset（Rect、View、RecyclerView、RecyclerView.State）

见示例：

DividerItemDecoration dividerItemDecoration = new 
    DividerItemDecoration(recyclerView.getContext(),layoutManager().getOrientation()){

    private int startMargin = Utils.fromDpToPx(10f);

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        if (parent.getChildAdapterPosition(view) == 0){
            outRect.set(0, startMargin, 0, 0);
        }
    }
};
recyclerView.addItemDecoration(dividerItemDecoration);

你能给recyclerView本身添加填充吗？这会改变列表项的边距（这不是我们想要的）而不是分隔符（这是我们想要的）。
