个人用起来最舒服的MVP框架

框架使用

关于项目代码中的基础框架搭建
presenter和view的基类中加入了内存的优化
map介绍：
契约：连接M,V,P三层（通过接口实现的方式）
Model:数据的获取（一般是网络请求）
Presenter：代码逻辑的处理
View：控件等的展示

1.设置好你的Apiservice

Apiservice是你一切的基础，如果你需要使用网络请求的话`.

public interface IApi {//登陆注册@POSTObservable<ResponseBody> postMap(@Url String url, @QueryMap Map<String, String> map);//GET复用@GETObservable<ResponseBody> getMap(@Url String url, @QueryMap Map<String, String> map);//delete复用@DELETEObservable<ResponseBody> deleteMap(@Url String url, @QueryMap Map<String, String> map);//文件上传@Multipart@POSTObservable<ResponseBody> filePost(@Url String url, @Query("content") String content, @Part List<MultipartBody.Part> list);//put请求复用@PUTObservable<ResponseBody> putMap(@Url String url, @QueryMap Map<String, String> map);
}

2.设计好你的契约

第二步，设置好你的契约，用来连接三个层

public interface Contract {interface IView<T>{void OnSuccess(T t);void OnError(String error);}//连接p层interface IPresenter{//发送复用void postMap(String url, Map<String, String> map, Class aClass);//获取复用void getMap(String url, Map<String, String> map, Class aClass);//删除复用void deleteMap(String url, Map<String, String> map, Class aClass);//多图上传void filePost(String url,String content, List<MultipartBody.Part>list, Class aClass);//put上传复用void putMap(String url, Map<String, String> map, Class aClass);}
//连接modelinterface IModel{//发送复用void postMap(String url, Map<String, String> map, Class aClass, ModelCallBack callBack);//获取复用void getMap(String url, Map<String, String> map, Class aClass, ModelCallBack callBack);//删除复用void deleteMap(String url, Map<String, String> map, Class aClass, ModelCallBack callBack);//多图上传void filePost(String url,String content, List<MultipartBody.Part>list, Class aClass,ModelCallBack callBack);//put上传复用void putMap(String url, Map<String, String> map, Class aClass,ModelCallBack callBack);}interface ModelCallBack<T>{void OnSuccess(T t);void OnError(String error);}}

3.构建好网络工具类（2/3）

public class MyHttpUtils {//retrofit对象private final Retrofit mretrofit;private IApi miapi;//单例模式（双重锁）private static MyHttpUtils MY_HTTP_UTILS;public static MyHttpUtils getInstance(){if(MY_HTTP_UTILS == null){synchronized (MyHttpUtils.class){if(MY_HTTP_UTILS == null){MY_HTTP_UTILS = new MyHttpUtils();}}}return MY_HTTP_UTILS;}//初始化okpublic MyHttpUtils(){//拦截器HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();//设置interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);//okOkHttpClient okHttpClient = new OkHttpClient.Builder().connectTimeout(5, TimeUnit.SECONDS).writeTimeout(5,TimeUnit.SECONDS).readTimeout(5,TimeUnit.SECONDS).addInterceptor(interceptor).addInterceptor(new HeaderInterceptor()).build();//retrofitmretrofit = new Retrofit.Builder().baseUrl(Constant.BASE_URL).addConverterFactory(GsonConverterFactory.create()).addCallAdapterFactory(RxJava2CallAdapterFactory.create()).client(okHttpClient).build();//结合miapi = mretrofit.create(IApi.class);}//接口public interface NetCallBack<T>{void onSuccess(T t);void onError(String error);}//网络判断public static boolean isNetWork(Context context){//系统ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);//网络NetworkInfo networkInfo = manager.getActiveNetworkInfo();if (networkInfo!=null){return networkInfo.isAvailable();}return false;}//头参class HeaderInterceptor implements Interceptor {@Overridepublic Response intercept(Chain chain) throws IOException {//sp存储SharedPreferences user = MyApplication.context.getSharedPreferences("user", Context.MODE_PRIVATE);//取两个参数String userId = user.getString("userId","");String sessionId = user.getString("sessionId","");
//            Log.i("头参",userId+"分割"+sessionId);//创建请求Request build = chain.request();Request request = build.newBuilder().addHeader("userId",userId).addHeader("sessionId",sessionId).addHeader("ak","0110010010000").build();return chain.proceed(request);}}////登陆注册等复用public void PostMap(String url, Map<String,String>map, final Class aClass, final NetCallBack netCallBack){miapi.postMap(url,map).subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread()).subscribe(new Observer<ResponseBody>() {@Overridepublic void onSubscribe(Disposable d) {}@Overridepublic void onNext(ResponseBody responseBody) {Gson gson = new Gson();try {Object o = gson.fromJson(responseBody.string(),aClass);if(netCallBack != null){netCallBack.onSuccess(o);}} catch (IOException e) {e.printStackTrace();}}@Overridepublic void onError(Throwable e) {if(netCallBack != null){netCallBack.onError(e.getMessage());}}@Overridepublic void onComplete() {}});}//get请求复用public void getMap(String url, Map<String,String>map, final Class aClass, final NetCallBack netCallBack){miapi.getMap(url, map).subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread()).subscribe(new Observer<ResponseBody>() {@Overridepublic void onSubscribe(Disposable d) {}@Overridepublic void onNext(ResponseBody responseBody) {Gson gson = new Gson();try {String obj = responseBody.string();Object o = gson.fromJson(obj, aClass);Log.i("信息",obj);if (netCallBack!=null){netCallBack.onSuccess(o);}} catch (IOException e) {e.printStackTrace();}}@Overridepublic void onError(Throwable e) {if (netCallBack!=null){netCallBack.onError(e.getMessage());}}@Overridepublic void onComplete() {}});}

4.IModel

model和p层中通过实现契约中对应的接口做到mvp的逻辑分层

public class IModel implements Contract.IModel {@Overridepublic void postMap(String url, Map<String, String> map, Class aClass, final Contract.ModelCallBack callBack) {MyHttpUtils.getInstance().PostMap(url, map, aClass, new MyHttpUtils.NetCallBack() {@Overridepublic void onSuccess(Object o) {callBack.OnSuccess(o);}@Overridepublic void onError(String error) {callBack.OnError(error);}});}@Overridepublic void getMap(String url, Map<String, String> map, Class aClass, final Contract.ModelCallBack callBack) {MyHttpUtils.getInstance().getMap(url, map, aClass, new MyHttpUtils.NetCallBack() {@Overridepublic void onSuccess(Object o) {callBack.OnSuccess(o);}@Overridepublic void onError(String error) {callBack.OnError(error);}});}@Overridepublic void deleteMap(String url, Map<String, String> map, Class aClass, final Contract.ModelCallBack callBack) {MyHttpUtils.getInstance().deleteMap(url, map, aClass, new MyHttpUtils.NetCallBack() {@Overridepublic void onSuccess(Object o) {callBack.OnSuccess(o);}@Overridepublic void onError(String error) {callBack.OnError(error);}});}@Overridepublic void filePost(String url,String content, List<MultipartBody.Part> list, Class aClass, Contract.ModelCallBack callBack) {MyHttpUtils.getInstance().filePost(url, content, list, aClass, new MyHttpUtils.NetCallBack() {@Overridepublic void onSuccess(Object o) {callBack.OnSuccess(o);}@Overridepublic void onError(String error) {callBack.OnError(error);}});}@Overridepublic void putMap(String url, Map<String, String> map, Class aClass, Contract.ModelCallBack callBack) {MyHttpUtils.getInstance().putMap(url, map, aClass, new MyHttpUtils.NetCallBack() {@Overridepublic void onSuccess(Object o) {callBack.OnSuccess(o);}@Overridepublic void onError(String error) {callBack.OnError(error);}});}
}

5.basepresenter和presenterImpl

public abstract class BasePresenter<V extends Contract.IView> implements Contract.IPresenter {//private IModel iModel;//弱引用private WeakReference<V> vWeakReference;//构造public BasePresenter(){iModel = new IModel();}//绑定public void attachView(V v){if(vWeakReference == null){vWeakReference = new WeakReference<>(v);}}//解绑public void detachView(){if(vWeakReference != null){vWeakReference.clear();vWeakReference = null;}}//getpublic V getView(){return vWeakReference.get();}public IModel getiModel(){return iModel;}}

public class PresenterImpl extends BasePresenter {@Overridepublic void postMap(String url, Map<String, String> map, Class aClass) {getiModel().postMap(url, map, aClass, new Contract.ModelCallBack() {@Overridepublic void OnSuccess(Object o) {getView().OnSuccess(o);}@Overridepublic void OnError(String error) {getView().OnError(error);}});}@Overridepublic void getMap(String url, Map<String, String> map, Class aClass) {getiModel().getMap(url, map, aClass, new Contract.ModelCallBack() {@Overridepublic void OnSuccess(Object o) {getView().OnSuccess(o);}@Overridepublic void OnError(String error) {getView().OnError(error);}});}@Overridepublic void deleteMap(String url, Map<String, String> map, Class aClass) {getiModel().deleteMap(url, map, aClass, new Contract.ModelCallBack() {@Overridepublic void OnSuccess(Object o) {getView().OnSuccess(o);}@Overridepublic void OnError(String error) {getView().OnError(error);}});}@Overridepublic void filePost(String url,String content, List<MultipartBody.Part> list, Class aClass) {getiModel().filePost(url, content, list, aClass, new Contract.ModelCallBack() {@Overridepublic void OnSuccess(Object o) {getView().OnSuccess(o);}@Overridepublic void OnError(String error) {getView().OnError(error);}});}@Overridepublic void putMap(String url, Map<String, String> map, Class aClass) {getiModel().putMap(url, map, aClass, new Contract.ModelCallBack() {@Overridepublic void OnSuccess(Object o) {getView().OnSuccess(o);}@Overridepublic void OnError(String error) {getView().OnError(error);}});}
}

6.view层基类及实类调用

实类继承基类重写抽象方法即可（fragment等基类方式相同）
实类中通过基类暴露出来的p对象调用网络方法即可实现网络请求
调用逻辑：
p调用到p层中的对应方法——p层中方法通过契约的桥梁调用到model中的对应方法，进行网络请求。
返回的数据按照与之相反的逻辑传递到实类view中的OnSuccess方法中
eg：p.getMap(Constant.InformationShowList_URL,map, Bean_Recommend.class);

public abstract class BaseActivity<P extends PresenterImpl> extends AppCompatActivity implements Contract.IView {//泛型对象public P p;@Overridepublic void onCreate(@Nullable Bundle savedInstanceState) {super.onCreate(savedInstanceState);init();}void init(){if(getLayout() != 0){setContentView(getLayout());if(p == null){p = initPresenter();p.attachView(this);}initView();}else {//参数不合法异常throw new IllegalArgumentException();}}//初始化protected abstract P initPresenter();protected abstract int getLayout();protected abstract void initView();
//    protected abstract void initData();@Overrideprotected void onDestroy() {super.onDestroy();if(p != null){p.detachView();p = null;}}}

总结

到这里就ok了，接下来就可以调用方法进行网络请求了
