java - Recyclerview - 从下到上重叠项目

Question

我已经为这样的项目设置了负边距:-

ItemDecoration.java

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;
    }
}

MainActivity.java

recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.addItemDecoration(new ItemDecorator(-80));

这会导致顶部项目在顶部项目重叠之后堆叠最低和下一个项目。我希望顶部项目与其下一个项目重叠，依此类推。

试试这个方法，反向渲染你的回收站 View 。

LinearLayoutManager layoutManager = new LinearLayoutManager(this);
        layoutManager.setReverseLayout(true);
        layoutManager.setStackFromEnd(true);
        recyclerView.setLayoutManager(layoutManager);
