为RecyclerView瀑布流添加foot时的一些问题

来源：互联网发布：js数组前面添加元素编辑：程序博客网时间：2024/05/20 19:46

根据viewType判断了对应position填充的布局后，在OnBindViewHolder中为foot布局设置setFullSpan(),

StaggeredGridLayoutManager.LayoutParams layoutParams1 =  (StaggeredGridLayoutManager.LayoutParams)holder.itemView.getLayoutParams();if (layoutParams1==null){    return;}layoutParams1.setFullSpan(true);

但是这样会有一个问题，在数据不多，或者说第一页加载的时候，layoutParam1为空，导致不能够正确显示充满全屏，可以改代码如下所示，可解决问题

StaggeredGridLayoutManager.LayoutParams lp = new StaggeredGridLayoutManager.LayoutParams(        StaggeredGridLayoutManager.LayoutParams.WRAP_CONTENT,StaggeredGridLayoutManager.LayoutParams.WRAP_CONTENT);holder.itemView.setLayoutParams(lp);StaggeredGridLayoutManager.LayoutParams layoutParams1 =  (StaggeredGridLayoutManager.LayoutParams)holder.itemView.getLayoutParams();if (layoutParams1==null){    return;}layoutParams1.setFullSpan(true);
