代码：
if (moduleBeanList != null) {
//有数据
//设置适配器
homeRecycleAdapter = new HomeRecycleViewAdapter(mContext, moduleBeanList);
rvHome.setAdapter(homeRecycleAdapter);
//recycleView不仅要设置适配器还要设置布局管理者,否则图片不显示
//第一个参数是上下文，第二个参数是只有一列
GridLayoutManager manager = new GridLayoutManager(getActivity(), 1);
rvHome.setLayoutManager(manager);
