OneFragment（首页以第一个fragment 里面的API是自行供应的接口）

public class OneFragment extends Fragment {

XRAdapter（适配器对条目）

recycle_item_a（banner轮播xml）

recycle_item_a（Recyclerview布局xml）

<?xml version="1.0" encoding="utf-8"?>

ViewHolderBa（Recyclerview小适配器）

public class ViewHolderBa extends RecyclerView.Adapter<ViewHolderBa.MyViewHolder>{
