Recyclerview - Top item should overlap next item and so on

问题

I have set the negative margin for items like this:-

public class ItemDecorator extends RecyclerView.ItemDecoration {
    private final int mSpace;

    public ItemDecorator(int space) {
        this.mSpace = space;
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        int position = parent.getChildAdapterPosition(view);
        if (position != 0)
            outRect.top = mSpace;
    }
}

This causes top item to stack lowest and next item after the top item overlaps it. I want top item to overlap its next item and so on.
