Api包裏倆個類

public interface BeanApi {
    @GET("nba/")
    Observable<Bean> bean( @QueryMap Map<String,String> map);
    //http://api.tianapi.com/nba/?key="+APIKEY+"&num=10
}

public class MyAPI {
    public static final  String APIKEY="71e58b5b2f930eaf1f937407acde08fe";
    public static final  String  utils="http://api.tianapi.com/";
}

MyApp

public class MyApp extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Fresco.initialize(this);
    }
}


model包

接口
public interface IMOdel {

    // 處理數據的方法
    void GetData(int a);
}

工具類

public class BeanModel implements IMOdel {
    ArrayList<Bean.NewslistBean> lists;

    private OnFinish onFinish;

    public BeanModel(OnFinish onFinish) {
        this.onFinish = onFinish;
    }

    // 建立接口
    public interface OnFinish{
        void onFinishLinisher(ArrayList<Bean.NewslistBean> lists);
    }

    @Override
    public void GetData(int a) {
        lists = new ArrayList<>();

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(MyAPI.utils)
                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
                .addConverterFactory(GsonConverterFactory.create())
                .build();

        // 經過動態代理得到網絡接口數據
        BeanApi apiService = retrofit.create(BeanApi.class);
//        Observable<Bean> data= (Observable<Bean>) apiService.bean();
        Map<String,String> map=new HashMap<>();
        map.put("key",MyAPI.APIKEY);
        map.put("num",a+"");
        Observable<Bean> data=apiService.bean(map);
        // 設置請求數據時候的線程
        data.subscribeOn(Schedulers.io())
                // 設置請求結束後的線程
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer<Bean>() {
                    @Override
                    public void onCompleted() {

                    }

                    @Override
                    public void onError(Throwable e) {

                    }

                    @Override
                    public void onNext(Bean bean) {
                       // Log.d("main2", "onNext: " + bean.newslist + "----");
                        lists = (ArrayList<Bean.NewslistBean>) bean.newslist;
                        onFinish.onFinishLinisher(lists);
                    }
                });
    }
}

 presenter包

public class UserPresenter implements BeanModel.OnFinish {
    private final IView iview;
    private final BeanModel userModel;

    public UserPresenter(IView iview) {
        this.iview = iview;
        userModel = new BeanModel(this);
    }

    // 處理model與view的邏輯
    public void getData(){
        userModel.GetData(10);
    }

    @Override
    public void onFinishLinisher(ArrayList<Bean.NewslistBean> lists) {
        iview.ShowData(lists);
    }
}

view包

public interface IView {
    void ShowData(ArrayList<Bean.NewslistBean> lists);
}
  
MainActivity類

public class MainActivity extends AppCompatActivity  implements IView{
     private RecyclerView rlv;
    UserPresenter presenter;
    MyXrecyclerviewAdapter adapter;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        init();
    }
    private void init() {
        rlv= (RecyclerView) findViewById(R.id.rlv);

        // 初始化數據
        initData();

    }

    private void initData() {
        presenter = new UserPresenter(this);
        presenter.getData();
    }

    @Override
    public void ShowData(ArrayList<Bean.NewslistBean> lists) {
        rlv.setLayoutManager(new LinearLayoutManager(this));
        rlv.setAdapter(adapter = new MyXrecyclerviewAdapter(lists,this));
    }
}

適配器

public class MyXrecyclerviewAdapter  extends RecyclerView.Adapter<MyXrecyclerviewAdapter.MyViewHolder> {    // 數據源    ArrayList<Bean.NewslistBean> lists;    // 上下文    Context context;    public MyXrecyclerviewAdapter(ArrayList<Bean.NewslistBean> lists, Context context) {        this.lists = lists;        this.context = context;    }    @Override    public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType)    {        MyViewHolder holder = new MyViewHolder(LayoutInflater.from(context).inflate(R.layout.recy_item, parent,                false));        return holder;    }    @Override    public void onBindViewHolder(MyViewHolder holder, int position)    {        holder.tv.setText(lists.get(position).title);        Uri uri = Uri.parse(lists.get(position).picUrl);        holder.img.setImageURI(uri);    }    @Override    public int getItemCount()    {        return lists.size();    }    class MyViewHolder extends RecyclerView.ViewHolder    {        TextView tv;        SimpleDraweeView img;        public MyViewHolder(View view)        {            super(view);            tv =  view.findViewById(R.id.recy_item_tv);            img = view.findViewById(R.id.recy_item_img);        }    }}
