CollapsingToolbarLayout只能使用RecyclerView,但不能使用ListView和GridView.

注意: – 滚动工作正常,但是在GridView列表滚动之后,它卡住了一些,而不是滚动更多,即使在gridView中有更多的行.仅滚动第八个gridView项目,第九个和第十个项目不显示…@H_502_3@
我搜索了很多链接,人们说它只在上面和在Lollipop版本中工作.以下版本有一些问题.@H_502_3@
是否可以在棒棒糖版本下运行折叠收费工具?@H_502_3@

解决方法
CoordinatorLayout使用RecyclerView或NestedScrollView更好地工作.根据您的要求,您可以使用RecyclerView与GridLayoutManger.

- </android.support.design.widget.CoordinatorLayout>
RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(this,2);
recyclerView.setLayoutManager(mLayoutManager);@H_502_3@
这是一个示例,演示了GridLayoutManger的用法:
