然后在代码里添加如下：

[html] view plain copy

print?

1. FullyLinearLayoutManager linearLayoutManager = new FullyLinearLayoutManager(this);  
2.         recyclerView.setNestedScrollingEnabled(false);  
3.         //设置布局管理器  
4.         recyclerView.setLayoutManager(linearLayoutManager);  

FullyLinearLayoutManager linearLayoutManager = new FullyLinearLayoutManager(this);一定不要忘了添加这行代码        recyclerView.setNestedScrollingEnabled(false);        //设置布局管理器        recyclerView.setLayoutManager(linearLayoutManager);
