我需要什么:

我可以将回收站视图分为两列，但是我不知道如何将主单元格放在回收站视图的顶部

I can divide recycler view to 2 columns, but I don't know how to put main cell on top of the recycler view

我不确定，但是也许我可以将其放入容器中并尝试在滚动过程中将其隐藏?就像我们在用户开始滚动工具栏时使用工具栏一样.

推荐答案

在onBindViewHolder方法中添加这些行

Add these lines in onBindViewHolder method

if(position == 0){
      StaggeredGridLayoutManager.LayoutParams layoutParams =  (StaggeredGridLayoutManager.LayoutParams) holder.itemView.getLayoutParams();
      layoutParams.setFullSpan(true);
}
