retrofit+ok+rxjava+fresco的demo

这是m层
package cui.com.myapplication.model;import cui.com.myapplication.Bean;import retrofit2.http.GET;import rx.Observable;/** * Created by ZMoffice on 2017.12.1. */public interface Mmodel {    @GET("v1/restserver/ting?method=baidu.ting.billboard.billList&type=1&size=10&offset=0")    Observable<Bean> getbean();}
这是v层
package cui.com.myapplication.view;import java.util.List;import cui.com.myapplication.Bean;/** * Created by ZMoffice on 2017.12.1. */public interface Mview {    void  setdata(List<Bean.SongListBean> list);}
这是p层
package cui.com.myapplication.presenter;import android.content.Context;import android.util.Log;import java.util.List;import cui.com.myapplication.Bean;import cui.com.myapplication.LoggingInterceptor;import cui.com.myapplication.model.Mmodel;import cui.com.myapplication.view.Mview;import okhttp3.OkHttpClient;import retrofit2.Retrofit;import retrofit2.adapter.rxjava.RxJavaCallAdapterFactory;import retrofit2.converter.gson.GsonConverterFactory;import rx.Observer;import rx.android.schedulers.AndroidSchedulers;import rx.schedulers.Schedulers;/** * Created by ZMoffice on 2017.12.1. */public class Mpresenter {    Mview view;    Mmodel model;    Context context;    public Mpresenter(Mview view, Context context) {        this.view = view;        this.context = context;    }    public void getdata()    {        OkHttpClient client=new OkHttpClient.Builder().                addInterceptor(new LoggingInterceptor()).                build();        Retrofit retrofit=new Retrofit.Builder()                .baseUrl("http://tingapi.ting.baidu.com/")                .client(client)                .addConverterFactory(GsonConverterFactory.create())                .addCallAdapterFactory(RxJavaCallAdapterFactory.create())                .build();        model=retrofit.create(Mmodel.class);        model.getbean()                .subscribeOn(Schedulers.io())            .observeOn(AndroidSchedulers.mainThread())            .subscribe(new Observer<Bean>() {            @Override            public void onCompleted() {            }            @Override            public void onError(Throwable e) {            }            @Override            public void onNext(Bean bean) {                Log.i("111111", "onNext: "+bean.toString());                List<Bean.SongListBean> list=bean.getSong_list();                view.setdata(list);            }        });    }}
mainactivity
package cui.com.myapplication;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.support.v7.widget.LinearLayoutManager;import android.support.v7.widget.RecyclerView;import android.widget.Button;import android.widget.Toast;import java.util.List;import butterknife.BindView;import butterknife.ButterKnife;import butterknife.OnClick;import cui.com.myapplication.presenter.Mpresenter;import cui.com.myapplication.view.Mview;public class MainActivity extends AppCompatActivity implements Mview {    @BindView(R.id.rv)    RecyclerView rv;    @BindView(R.id.bt)    Button bt;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ButterKnife.bind(this);        LinearLayoutManager l = new LinearLayoutManager(MainActivity.this);        rv.setLayoutManager(l);        Mpresenter p = new Mpresenter(this, this);        p.getdata();    }    @Override    public void setdata(List<Bean.SongListBean> list) {        Myadp adp = new Myadp(list, MainActivity.this);        rv.setAdapter(adp);    }    @OnClick(R.id.bt)    public void onViewClicked() {        Toast.makeText(MainActivity.this,"笑死我了",Toast.LENGTH_SHORT).show();    }}
适配器
package cui.com.myapplication;import android.content.Context;import android.net.Uri;import android.support.v7.widget.RecyclerView;import android.util.Log;import android.view.View;import android.view.ViewGroup;import android.widget.TextView;import com.facebook.drawee.view.SimpleDraweeView;import java.util.List;/** * Created by ZMoffice on 2017.12.1. */public class Myadp extends RecyclerView.Adapter<Myadp.Vh> {    List<Bean.SongListBean> list;    Context context;    public Myadp(List<Bean.SongListBean> list, Context context) {        this.list = list;        this.context = context;    }    @Override    public Vh onCreateViewHolder(ViewGroup parent, int viewType) {        View v=View.inflate(context, R.layout.item,null);        return new Vh(v);    }    @Override    public void onBindViewHolder(Vh holder, int position) {        Uri uri=Uri.parse(list.get(position).getPic_small());        Log.i("img=============",list.get(position).getPic_small());        holder.img.setImageURI(uri);        Log.i("img=============",list.get(position).getTitle());        holder.tv.setText(list.get(position).getTitle());    }    @Override    public int getItemCount() {        return list.size();    }    class Vh extends RecyclerView.ViewHolder {        SimpleDraweeView img;        TextView tv;        public Vh(View v) {            super(v);            img =  v.findViewById(R.id.img);            tv = v.findViewById(R.id.tv);        }    }}
bean类可以自己替换，拦截器也可以自定义，
一定注意fresco的初始化
App
package cui.com.myapplication;import android.app.Application;import com.facebook.drawee.backends.pipeline.Fresco;/** * Created by ZMoffice on 2017.12.1. */public class App extends Application {    @Override    public void onCreate() {        super.onCreate();        Fresco.initialize(this);    }}
