主Activity

public class SupperActivity extends BaseMvpActivity<SupperView, SupperPresenter> implements SupperView {    @BindView(R.id.rv)    RecyclerView rv;    @Override    public SupperPresenter initPresenter() {        return new SupperPresenter(this);    }    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_supper);        ButterKnife.bind(this);        p.login();//调用 p层定义的方法    }    @Override    public void Success(Bean bean) {        //线性格式  布局管理器        LinearLayoutManager manager = new LinearLayoutManager(this,LinearLayoutManager.VERTICAL,false);        rv.setLayoutManager(manager);        //适配器        SupperApdata adapter = new SupperApdata(SupperActivity.this,bean);        rv.setAdapter(adapter);  //绑定    }   //失败    @Override    public void Failure(Exception e) {    }    //内存泄漏    @Override    public void onDestroy() {        super.onDestroy();        //解绑        p.data();    }}

主布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.my_12_6.SupperActivity">    <android.support.v7.widget.RecyclerView        android:id="@+id/rv"        android:layout_width="match_parent"        android:layout_height="match_parent">    </android.support.v7.widget.RecyclerView></LinearLayout>

BaseMvpActicity 相当于我们主布局继承的Activity

public abstract class BaseMvpActivity<V,P extends BasePresenter<V>> extends Activity{    public P p; //p层的泛型    public abstract P initPresenter();    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        p = initPresenter(); //实例化    }    //这里是相当于p层持有了View层的接口    @Override    protected void onResume() {        super.onResume();        p.Hold((V) this);    }     //释放持有View的接口， 防止内存泄漏    @Override    protected void onDestroy() {        super.onDestroy();        p.Datach();    }}

网络请求

public interface objGet {    @GET("/nba")    Observable<Bean> get(@QueryMap Map<String ,String> Map);}

MyApp

//数据的初始化public class MyApp extends Application {    public static objGet objget;    @Override    public void onCreate() {        super.onCreate();        Fresco.initialize(this);//图片框架的初始化        Retrofit retrofit = new Retrofit.Builder()                .baseUrl("http://api.tianapi.com")//请求头                .addConverterFactory(GsonConverterFactory.create())//数据的解析                .addCallAdapterFactory(RxJava2CallAdapterFactory.create()) //数据解析                .build();        objget = retrofit.create(objGet.class);//拿到objget里的请求方式    }}

View层

public interface SupperView  {    void Success(Bean bean);    void Failure(Exception e);}

Model层接口

public interface SupperModleINf {    void Success(Bean bean);    void Failure(Exception e);}

Modle层类

public class SupperModle extends SupperActivity {    //自己定义一个请求的方法    public  void getData(final SupperModleINf supperModleINf){        //创建HashMap        Map<String, String> map = new HashMap<>();        //传值        map.put("key","71e58b5b2f930eaf1f937407acde08fe");        map.put("num","10");        MyApp.objget.get(map)                .subscribeOn(Schedulers.io())//子线程                .observeOn(AndroidSchedulers.mainThread())//主线程                .subscribe(new Consumer<Bean>() {                    @Override                    public void accept(Bean bean) throws Exception {                        supperModleINf.Success(bean);                    }                });    }}

Presenter层

public class SupperPresenter extends BasePresenter<SupperView>{    SupperModle supperModle;  //model层的实体类    //WeakReference弱引用    WeakReference<SupperView> supperViewWeakReference;    //构造参数    public SupperPresenter(SupperActivity supperModle) {        this.supperModle = new  SupperModle();    }    //自己定义的方法    public void login(){        //  判断//        view.success();        //new LoginModelImpl.LoginModelCallBack() 用modle层的实体类莱调用实体类的接口 得到成功的方法        supperModle.getData(new SupperModleINf() {            //成功的方法            @Override            public void Success(Bean bean) {                view.Success(bean);            }                //失败的方法            @Override            public void Failure(Exception e) {                 view.Failure(e);            }        });    }    // 绑定 内存泄漏    public  void  datach(SupperView view){        supperViewWeakReference = new WeakReference(view);    }    //解绑    public  void  data(){        supperViewWeakReference.clear();    }}

适配器

public class SupperApdata extends RecyclerView.Adapter<SupperApdata.ViewHolder> {    private Context context;    private Bean bean;    public SupperApdata(Context context, Bean bean) {        this.context = context;        this.bean = bean;    }    @Override    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View view = View.inflate(context, R.layout.rv_litem, null);        return new ViewHolder(view);    }    @Override    public void onBindViewHolder(ViewHolder holder, int position) {        //加载文字        holder.tv.setText(bean.getNewslist().get(position).getTitle());        holder.iv.setImageURI(bean.getNewslist().get(position).getPicUrl());    }    @Override    public int getItemCount() {        return bean.getNewslist().size();    }    static    public class ViewHolder extends RecyclerView.ViewHolder {        @BindView(R.id.iv)        SimpleDraweeView iv;        @BindView(R.id.tv)        TextView tv;        public ViewHolder(View itemView) {            super(itemView);            ButterKnife.bind(this, itemView);        }    }}

封装View层

 //这里的V就相当于View层public class BasePresenter<V>{   // v相当于View层的接口    public  V view;  //这里相当于把View初始化    //这里相当于持有View层  public  void  Hold(V views){       this.view = views;   }   //防止内存泄漏   public  void Datach(){       view =null;   }}

适配器布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent">    <com.facebook.drawee.view.SimpleDraweeView        android:layout_width="100dp"        android:layout_height="100dp"        android:id="@+id/iv"/>    <TextView        android:layout_width="match_parent"        android:layout_height="100dp"        android:id="@+id/tv"/></LinearLayout>
