Retrofit2 + RxJava + Okhttp + RecyclerView用MVP架构展示数据

写代码思路流程：

//1.权限和依赖
//2.布局文件
//3.生成实体bean类
//4.封装工具类 Retrofit + RxJava + OkHttp
//5.搭建MVP架构
//6.创建适配器
//7.在Activity或者Fragment中进行加载布局管理器和绑定适配器

 

 

效果图：

 

a.添加联网权限：

<uses-permission android:name="android.permission.INTERNET"></uses-permission>

b.依赖：（带libs的依赖需要自己导入jar包，也可以自己在网上搜直接添加）

compile 'com.squareup.okhttp3:okhttp:3.9.0'
compile 'io.reactivex:rxjava:1.0.14'
compile 'io.reactivex:rxandroid:1.0.1'
compile 'com.squareup.retrofit2:retrofit:2.0.2'                  //Retrofit2库文件
compile 'com.squareup.retrofit2:converter-gson:2.0.2'           //支持Gson解析
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'           //支持RxJava
compile 'com.jcodecraeer:xrecyclerview:1.3.2'
compile 'com.github.bumptech.glide:glide:3.7.0'

 

布局文件：

activity_main.xml

1. <?xml version="1.0" encoding="utf-8"?>
2. <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. xmlns:app="http://schemas.android.com/apk/res-auto"
4. xmlns:tools="http://schemas.android.com/tools"
5. android:layout_width="match_parent"
6. android:layout_height="match_parent"
7. tools:context="com.ccm.mvpretrofitrxjava.activity.MainActivity">
8.  
9. <com.jcodecraeer.xrecyclerview.XRecyclerView
10. android:id="@+id/xrv"
11. android:layout_width="match_parent"
12. android:layout_height="match_parent"></com.jcodecraeer.xrecyclerview.XRecyclerView>
13.  
14. </android.support.constraint.ConstraintLayout>

 

 

recy_item

1. <?xml version="1.0" encoding="utf-8"?>
2. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
3. android:layout_width="match_parent"
4. android:layout_height="50dp"
5. android:orientation="horizontal">
6.  
7. <ImageView
8. android:id="@+id/iv_item"
9. android:layout_width="50dp"
10. android:layout_height="match_parent" />
11.  
12. <TextView
13. android:id="@+id/tv_item"
14. android:layout_width="match_parent"
15. android:layout_height="match_parent"
16. android:text="我是文本"
17. android:textSize="20sp"/>
18. </LinearLayout>

封装工具类：

RequestApi接口

1. public interface RequestApi {
2. public static final String BASE_URL = "http://api.svipmovie.com/front/";
3.  
4. //get和RxJava
5. @GET("columns/getVideoList.do?catalogId=402834815584e463015584e539330016&pnum=2")
6. Observable<Bean> getData();
7.  
8. @Streaming
9. @POST("{fileName}")
10. Call<ResponseBody> downloadFile(@Path("fileName") String fileName, @Header("Range") String range);
11.  
12. @Streaming
13. @POST("{fileName}")
14. Call<ResponseBody> getFileLenght(@Path("fileName") String fileName);
15. }

RetrofitUtils类：

1. public class RetrofitUtils {
2. //支持RxJava
3. public static RequestApi getNetDatas(){
4. OkHttpClient client = new OkHttpClient.Builder()
5. .connectTimeout(5, TimeUnit.SECONDS)
6. .readTimeout(5, TimeUnit.SECONDS)
7. // .addNetworkInterceptor(new MyInterceptro())
8. .build();
9.  
10. Retrofit retrofit = new Retrofit.Builder()
11. .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
12. .addConverterFactory(GsonConverterFactory.create())
13. .client(client)
14. .baseUrl(RequestApi.BASE_URL)
15. .build();
16.  
17. RequestApi api = retrofit.create(RequestApi.class);
18.  
19. return api;
20. }
21.  
22.  
23. public static RequestApi download(){
24. OkHttpClient client = new OkHttpClient.Builder()
25. .connectTimeout(5, TimeUnit.SECONDS)
26. .readTimeout(5, TimeUnit.SECONDS)
27. //.addNetworkInterceptor(new MyInterceptro())
28. .build();
29.  
30. Retrofit retrofit = new Retrofit.Builder()
31. .client(client)
32. .baseUrl("http://10.0.2.2:8080/aaa/")
33. .build();
34.  
35. RequestApi api = retrofit.create(RequestApi.class);
36.  
37. return api;
38. }
39. }

view层：

1. public interface IRecyView {
2. void showRecy(Bean bean);
3. }

 

 

model层：

IRecyModel接口

1. public interface IRecyModel {
2. void recy(Observer<Bean> observer);
3. }

RecyModel是IRecyView的实现类

1. public class RecyModel implements IRecyModel {
2. @Override
3. public void recy(Observer<Bean> observer) {
4. //OkHttpUtils.getInstance().doGet("http://api.svipmovie.com/front/columns/getVideoList.do?catalogId=402834815584e463015584e539330016", callback);
5. RetrofitUtils.getNetDatas().getData()
6. .subscribeOn(Schedulers.io()) //定义被观察者在子线程执行
7. .observeOn(AndroidSchedulers.mainThread()) //定义观察者在主线程执行
8. .subscribe(observer);
9. }
10. }

presenter层：

1. public class RecyPresenter {
2. private IRecyView view;
3. private IRecyModel model;
4.  
5.  
6. public RecyPresenter(IRecyView view) {
7. this.view = view;
8. model = new RecyModel();
9. }
10.  
11. public void showRecy(){
12. model.recy(new Observer<Bean>() {
13. @Override
14. public void onCompleted() {
15. Log.i("我用retrofit+RxJava好使啦", "onCompleted: ");
16. }
17.  
18. @Override
19. public void onError(Throwable e) {
20. Log.i("我用retrofit+RxJava好使啦", "onError: ");
21. }
22.  
23. @Override
24. public void onNext(Bean bean) {
25. Log.i("我用retrofit+RxJava好使啦", "onNext: ");
26. view.showRecy(bean);
27. }
28. });
29. }
30.  
31. //解绑
32. public void onDestory(){
33. view = null;
34. }
35. }

适配器：

1. public class MyRecyAdapter extends RecyclerView.Adapter<MyRecyAdapter.MyViewHolder>{
2. private Context context;
3. private Bean bean;
4.  
5. public MyRecyAdapter(Context context, Bean bean) {
6. this.context = context;
7. this.bean = bean;
8. }
9.  
10. @Override
11. public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
12. View view = LayoutInflater.from(context).inflate(R.layout.recy_item, parent, false);
13. MyViewHolder holder = new MyViewHolder(view);
14. return holder;
15. }
16.  
17. @Override
18. public void onBindViewHolder(MyViewHolder holder, int position) {
19. Glide.with(context).load(bean.getRet().getList().get(position).getPic()).into(holder.iv_item);
20. holder.tv_item.setText(bean.getRet().getList().get(position).getDescription());
21. }
22.  
23. @Override
24. public int getItemCount() {
25. return bean.getRet().getList().size();
26. }
27.  
28. static class MyViewHolder extends RecyclerView.ViewHolder{
29.  
30. ImageView iv_item;
31. TextView tv_item;
32.  
33. public MyViewHolder(View itemView) {
34. super(itemView);
35. iv_item = itemView.findViewById(R.id.iv_item);
36. tv_item = itemView.findViewById(R.id.tv_item);
37. }
38. }
39. }

 

MainActivity：

1. //1.权限和依赖
2. //2.布局文件
3. //3.生成实体bean类
4. //4.封装工具类 Retrofit + RxJava + OkHttp
5. //5.搭建MVP架构
6. //6.创建适配器
7. //7.在Activity或者Fragment中进行加载布局管理器和绑定适配器
8. public class MainActivity extends AppCompatActivity implements IRecyView{
9.  
10. private XRecyclerView xrv;
11. private RecyPresenter presenter;
12.  
13. @Override
14. protected void onCreate(Bundle savedInstanceState) {
15. super.onCreate(savedInstanceState);
16. setContentView(R.layout.activity_main);
17.  
18. initView();
19. presenter = new RecyPresenter(this);
20. presenter.showRecy();
21. }
22.  
23.  
24. private void initView() {
25. xrv = (XRecyclerView) findViewById(R.id.xrv);
26. LinearLayoutManager manager = new LinearLayoutManager(this);
27. manager.setOrientation(LinearLayoutManager.VERTICAL);
28. xrv.setLayoutManager(manager);
29. //下面是加载更多的方法
30. }
31. @Override
32. public void showRecy(Bean bean) {
33. MyRecyAdapter myRecyAdapter = new MyRecyAdapter(this, bean);
34. xrv.setAdapter(myRecyAdapter);
35. }
36. }
