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
生成实体bean类：
public class Bean {
private String msg;
private RetEntity ret;
private String code;
public String getMsg() {
return msg;
}
public void setMsg(String msg) {
this.msg = msg;
}
public RetEntity getRet() {
return ret;
}
public void setRet(RetEntity ret) {
this.ret = ret;
}
public String getCode() {
return code;
}
public void setCode(String code) {
this.code = code;
}
public static class RetEntity {
private AdvEntity adv;
private int pnum;
private int totalRecords;
private int records;
private int totalPnum;
private List bannerList;
private List list;
public AdvEntity getAdv() {
return adv;
}
public void setAdv(AdvEntity adv) {
this.adv = adv;
}
public int getPnum() {
return pnum;
}
public void setPnum(int pnum) {
this.pnum = pnum;
}
public int getTotalRecords() {
return totalRecords;
}
public void setTotalRecords(int totalRecords) {
this.totalRecords = totalRecords;
}
public int getRecords() {
return records;
}
public void setRecords(int records) {
this.records = records;
}
public int getTotalPnum() {
return totalPnum;
}
public void setTotalPnum(int totalPnum) {
this.totalPnum = totalPnum;
}
public List getBannerList() {
return bannerList;
}
public void setBannerList(List bannerList) {
this.bannerList = bannerList;
}
public List getList() {
return list;
}
public void setList(List list) {
this.list = list;
}
public static class AdvEntity {
private String imgURL;
private String dataId;
private String htmlURL;
private String shareURL;
private String title;
public String getImgURL() {
return imgURL;
}
public void setImgURL(String imgURL) {
this.imgURL = imgURL;
}
public String getDataId() {
return dataId;
}
public void setDataId(String dataId) {
this.dataId = dataId;
}
public String getHtmlURL() {
return htmlURL;
}
public void setHtmlURL(String htmlURL) {
this.htmlURL = htmlURL;
}
public String getShareURL() {
return shareURL;
}
public void setShareURL(String shareURL) {
this.shareURL = shareURL;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
}
public static class ListEntity {
private int airTime;
private String duration;
private String loadtype;
private int score;
private String angleIcon;
private String dataId;
private String description;
private String loadURL;
private String shareURL;
private String pic;
private String title;
private String roomId;
public int getAirTime() {
return airTime;
}
public void setAirTime(int airTime) {
this.airTime = airTime;
}
public String getDuration() {
return duration;
}
public void setDuration(String duration) {
this.duration = duration;
}
public String getLoadtype() {
return loadtype;
}
public void setLoadtype(String loadtype) {
this.loadtype = loadtype;
}
public int getScore() {
return score;
}
public void setScore(int score) {
this.score = score;
}
public String getAngleIcon() {
return angleIcon;
}
public void setAngleIcon(String angleIcon) {
this.angleIcon = angleIcon;
}
public String getDataId() {
return dataId;
}
public void setDataId(String dataId) {
this.dataId = dataId;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public String getLoadURL() {
return loadURL;
}
public void setLoadURL(String loadURL) {
this.loadURL = loadURL;
}
public String getShareURL() {
return shareURL;
}
public void setShareURL(String shareURL) {
this.shareURL = shareURL;
}
public String getPic() {
return pic;
}
public void setPic(String pic) {
this.pic = pic;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getRoomId() {
return roomId;
}
public void setRoomId(String roomId) {
this.roomId = roomId;
}
}
}
} 封装工具类：
RequestApi接口
public interface RequestApi {
public static final String BASE_URL = "http://api.svipmovie.com/front/";
//get和RxJava
@GET("columns/getVideoList.do?catalogId=402834815584e463015584e539330016&pnum=2")
Observable getData();
@Streaming
@POST("{fileName}")
Call downloadFile(@Path("fileName") String fileName, @Header("Range") String range);
@Streaming
@POST("{fileName}")
Call getFileLenght(@Path("fileName") String fileName);
}
RetrofitUtils类：
public class RetrofitUtils {
//支持RxJava
public static RequestApi getNetDatas(){
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(5, TimeUnit.SECONDS)
.readTimeout(5, TimeUnit.SECONDS)
// .addNetworkInterceptor(new MyInterceptro())
.build();
Retrofit retrofit = new Retrofit.Builder()
.addCallAdapterFactory(RxJavaCallAdapterFactory.create())
.addConverterFactory(GsonConverterFactory.create())
.client(client)
.baseUrl(RequestApi.BASE_URL)
.build();
RequestApi api = retrofit.create(RequestApi.class);
return api;
}
public static RequestApi download(){
OkHttpClient client = new OkHttpClient.Builder()
.connectTimeout(5, TimeUnit.SECONDS)
.readTimeout(5, TimeUnit.SECONDS)
//.addNetworkInterceptor(new MyInterceptro())
.build();
Retrofit retrofit = new Retrofit.Builder()
.client(client)
.baseUrl("http://10.0.2.2:8080/aaa/")
.build();
RequestApi api = retrofit.create(RequestApi.class);
return api;
}
}view层：
public interface IRecyView {
void showRecy(Bean bean);
}model层：
IRecyModel接口
public interface IRecyModel {
void recy(Observer observer);
} RecyModel是IRecyView的实现类
public class RecyModel implements IRecyModel {
@Override
public void recy(Observer observer) {
//OkHttpUtils.getInstance().doGet("http://api.svipmovie.com/front/columns/getVideoList.do?catalogId=402834815584e463015584e539330016", callback);
RetrofitUtils.getNetDatas().getData()
.subscribeOn(Schedulers.io()) //定义被观察者在子线程执行
.observeOn(AndroidSchedulers.mainThread()) //定义观察者在主线程执行
.subscribe(observer);
}
} presenter层：
public class RecyPresenter {
private IRecyView view;
private IRecyModel model;
public RecyPresenter(IRecyView view) {
this.view = view;
model = new RecyModel();
}
public void showRecy(){
model.recy(new Observer() {
@Override
public void onCompleted() {
Log.i("我用retrofit+RxJava好使啦", "onCompleted: ");
}
@Override
public void onError(Throwable e) {
Log.i("我用retrofit+RxJava好使啦", "onError: ");
}
@Override
public void onNext(Bean bean) {
Log.i("我用retrofit+RxJava好使啦", "onNext: ");
view.showRecy(bean);
}
});
}
//解绑
public void onDestory(){
view = null;
}
} 适配器：
public class MyRecyAdapter extends RecyclerView.Adapter{
private Context context;
private Bean bean;
public MyRecyAdapter(Context context, Bean bean) {
this.context = context;
this.bean = bean;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(context).inflate(R.layout.recy_item, parent, false);
MyViewHolder holder = new MyViewHolder(view);
return holder;
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
Glide.with(context).load(bean.getRet().getList().get(position).getPic()).into(holder.iv_item);
holder.tv_item.setText(bean.getRet().getList().get(position).getDescription());
}
@Override
public int getItemCount() {
return bean.getRet().getList().size();
}
static class MyViewHolder extends RecyclerView.ViewHolder{
ImageView iv_item;
TextView tv_item;
public MyViewHolder(View itemView) {
super(itemView);
iv_item = itemView.findViewById(R.id.iv_item);
tv_item = itemView.findViewById(R.id.tv_item);
}
}
}
MainActivity：
//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
public class MainActivity extends AppCompatActivity implements IRecyView{
private XRecyclerView xrv;
private RecyPresenter presenter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
presenter = new RecyPresenter(this);
presenter.showRecy();
}
private void initView() {
xrv = (XRecyclerView) findViewById(R.id.xrv);
LinearLayoutManager manager = new LinearLayoutManager(this);
manager.setOrientation(LinearLayoutManager.VERTICAL);
xrv.setLayoutManager(manager);
//下面是加载更多的方法
}
@Override
public void showRecy(Bean bean) {
MyRecyAdapter myRecyAdapter = new MyRecyAdapter(this, bean);
xrv.setAdapter(myRecyAdapter);
}
}
