Question

如何在 RecyclerView 中重叠项目？就像堆叠卡片。

提前致谢。

Answer 1

您必须编写自己的 LayoutManager 或扩展 LinearLayoutManager

Answer 2

要重叠 recyclerView 行，您可以使用它。

将此 class 添加到您的 activity。您可以自定义 vertOverlap。

   public class OverlapDecoration extends RecyclerView.ItemDecoration {

    private final static int vertOverlap = -40;

    @Override
    public void getItemOffsets (Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        final int itemPosition = parent.getChildAdapterPosition(view);
        if (itemPosition == 0) {
            return; }
        outRect.set(0, vertOverlap, 0, 0);


    }
} `

然后在设置其布局管理器之前将装饰添加到 recyclerView，我们就完成了。

    mRecyclerView.addItemDecoration(new OverlapDecoration());
    mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
