ZhuyeActivity（首页布局含TabLayout）

public class ZhuyeActivity extends AppCompatActivity {
 private ViewPager viewpager;
 private TabLayout tablayout;
 private FragmentAdapter adapter;
 private List<Fragment> fragments;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);

  fragments.add(threeFragment);
  fragments.add(fourFragment);
  adapter = new FragmentAdapter(getSupportFragmentManager(),fragments);
  viewpager.setAdapter(adapter);
  tablayout.setupWithViewPager(viewpager);
 }
}

activity_zhuye（首页布局xml文件）

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 {
 private XRecyclerView xr;
 private List<String> list = new ArrayList<>();
 //获取数据的开始
 private int curr;
 private XRAdapter adapter;
 @Nullable
 @Override
 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
  View view = inflater.inflate(R.layout.y1, null, false);
  //初始化xr控件
  xr=(XRecyclerView)view.findViewById(R.id.xre_xrv);

  //加布局管理器
  LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
  layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
  xr.setLayoutManager(layoutManager);

  getData(API.TYPE_HOME,1);
  xr.setLoadingListener(new XRecyclerView.LoadingListener() {

    /*下拉刷新*/

   @Override
   public void onRefresh() {
    curr=0;
    list.clear();
    getData(API.TYPE_HOME,curr);
    xr.refreshComplete();
   }

    /*上拉加载*/

   @Override
   public void onLoadMore() {
    /*curr++;
    getData(API.TYPE_HOME,curr);
    xr.refreshComplete();*/
//    xr.loadMoreComplete();
   }
  });
  return view;

 private void getData(String url,int curr){
  OkHttp3Utils.getInstance().doGet(url, new GsonObjectCallback<MyGsonFr>() {

    XRAdapter mxradapter=new XRAdapter(getActivity(),myGsonFr.getTop_stories());
    xr.setAdapter(mxradapter);
   }

   @Override
   public void onFailed(Call call, IOException e) {

   }
  });

XRAdapter（适配器对条目）

public class XRAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

  Typeone,Typetwo,Typethree,Typefour,Typefive,Typesix,Typeseven;

 }

 @Override

 }

 @Override
 public int getItemCount() {
  return 2;
 }

 @Override

  if(position==0){
   return Item_Type.Typeone.ordinal();
  }else if(position==1){

  return -1;
 }
 class ViewHolderA extends RecyclerView.ViewHolder{

  private RecyclerView re;
  public ViewHolderB(View itemView) {
   super(itemView);
   re = (RecyclerView) itemView.findViewById(R.id.id_recyclerview);
  }
 }
}

recycle_item_a（banner轮播xml）

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical" android:layout_width="match_parent"
 android:layout_height="150dp">
 <com.youth.banner.Banner
  android:id="@+id/mybanner"
  android:layout_width="match_parent"
  android:layout_height="150dp">
 </com.youth.banner.Banner>
</LinearLayout>

recycle_item_a（Recyclerview布局xml）

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

 <android.support.v7.widget.RecyclerView
  android:id="@+id/id_recyclerview"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"

</LinearLayout>

ViewHolderBa（Recyclerview小适配器）

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

 List<MyGsonFr.TopStoriesBean> lists;
 Context mc;

 public ViewHolderBa(List<MyGsonFr.TopStoriesBean> lists, Context mc) {
 this.lists = lists;

 return holder;
 }

 @Override
 public void onBindViewHolder(MyViewHolder holder, int position) {
 holder.tv.setText(lists.get(position).getTitle());
 ImageLoader instance = ImageLoader.getInstance();
 instance.displayImage(lists.get(position).getImage(),holder.img);
 }

 @Override
 public int getItemCount() {
 return lists.size();
 }

 class MyViewHolder extends RecyclerView.ViewHolder {

 TextView tv;
 ImageView img;

 public MyViewHolder(View view) {
  super(view);
  tv = (TextView) view.findViewById(R.id.text_a1);
  img = (ImageView) view.findViewById(R.id.img_a1);
 }
 }
