用到的依赖

compile 'com.jakewharton:butterknife:8.8.1'annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'compile 'com.android.support:recyclerview-v7:26.1.0'compile 'com.squareup.okhttp3:okhttp:3.9.0'compile 'com.squareup.okio:okio:1.13.0'compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'compile 'com.facebook.fresco:fresco:1.5.0'

App图片框架的初始化

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

View层

public interface EvMainView {    void Suuer(EvBean bean);//成功    void Defeat(Exception e);//失败}

Modle层的接口

public interface EvMainModleInterface {    void Suuer(EvBean bean);//成功    void Defeat(Exception e);//失败}

Modle层的实体类

public class EvMainModle {    //获取数据传入 modle接口    public  void getData(final EvMainModleInterface evMainModleInterface){        OkhttpUtils.getInstance().asy(null, "http://v.juhe.cn/weixin/query?key=88f7bbc507e3ecacfaeab2b47dd8936f", new AbstractUiCallBack<EvBean>() {            @Override            public void success(EvBean bean) {                evMainModleInterface.Suuer(bean);            }            @Override            public void failure(Exception e) {                evMainModleInterface.Defeat(e);            }        });    }}

Prenter层

public class EvPresenter {    EvMainModle em;//modle类    EvMainView ev;//View接口    public EvPresenter(EvMainView ev) {        this.ev = ev;        this.em = new EvMainModle();    }    //获取参数    public  void  getData(){        em.getData(new EvMainModleInterface() {            @Override            public void Suuer(EvBean bean) {                if (ev!=null){                    ev.Suuer(bean);                }            }            @Override            public void Defeat(Exception e) {                if(ev ==null ){                    ev.Defeat(e);                }            }        });    }    //防止内存泄漏    public  void datch(){        ev =null;    }}

适配器

public class EvApdata extends RecyclerView.Adapter<EvApdata.ViewHolder> {    //传入上下文    Context context;     List<EvBean.ResultBean.ListBean> listDa;        //有参构造    public EvApdata(Context context) {        this.context = context;    }        //这里是添加数据  更新适配器    public void addData(List<EvBean.ResultBean.ListBean> list) {        if(listDa==null){            listDa=new ArrayList<>();        }       listDa.addAll(list);        notifyDataSetChanged();    }    @Override    public EvApdata.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {        View  view = View.inflate(context,R.layout.rcy_main,null);        return new ViewHolder(view);    }    @Override    public void onBindViewHolder(EvApdata.ViewHolder holder, int position) {        holder.tv1.setText(listDa.get(position).getTitle());        holder.tv2.setText(listDa.get(position).getTitle());        Uri uri =  Uri.parse(listDa.get(position).getFirstImg());        DraweeController controller = Fresco.newDraweeControllerBuilder()                .setUri(uri)                .setAutoPlayAnimations(true)                .build();        holder.simpdv.setController(controller);    }    @Override    public int getItemCount(){        return listDa==null?0:listDa.size();    }    public class ViewHolder extends RecyclerView.ViewHolder {        SimpleDraweeView simpdv;        TextView tv1,tv2;        public ViewHolder(View itemView) {            super(itemView);            simpdv = itemView.findViewById(R.id.simpdv);            tv1 = itemView.findViewById(R.id.tv1);            tv2 = itemView.findViewById(R.id.tv2);        }    }    public UpdateUiListener listener;    public void setListener(UpdateUiListener listener) {        this.listener = listener;    }    //更新接口数据    public interface UpdateUiListener {        public void setTotal(String total, String num, boolean allCheck);    }}

主方法

public class MainActivity extends AppCompatActivity implements EvMainView {    EvApdata evApdata;    EvPresenter evPresenter;    EvBean evBean;    @BindView(R.id.rcv)    RecyclerView rcv;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        rcv.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));        evPresenter = new EvPresenter(this);        evPresenter.getData();        evApdata = new EvApdata(this);    }    @Override    public void Suuer(EvBean bean) {        //这里是调用适配器的添加方法 来获取请求到的数据        evApdata.addData(bean.getResult().getList());        rcv.setAdapter(evApdata);    }    @Override    public void Defeat(Exception e) {    }    //防止内存泄漏    @Override    protected void onDestroy() {        super.onDestroy();        evPresenter.datch();    }}
