MVP+Retrofit+RxJava的简单使用(仅登录模块)

首先要封装好的Retrofit工具类 —— RetrofitManager

package com.example.mvpretrofitrxjava.utils;

import java.util.concurrent.TimeUnit;

import okhttp3.OkHttpClient;
import retrofit2.Retrofit;
import retrofit2.adapter.rxjava2.RxJava2CallAdapterFactory;
import retrofit2.converter.gson.GsonConverterFactory;

/**
 * Created by DELL on 2018/7/11.
 */

public class RetrofitManager {

    //设置公共的请求url
    private static String BASE_URL = "https://www.zhaoapi.cn/";
    private final Retrofit retrofit;

    private static class SingleHolder {
        private static final RetrofitManager _INSTANCE = new RetrofitManager(BASE_URL);
    }

    public static RetrofitManager getDefault() {

        return SingleHolder._INSTANCE;

    }

    private RetrofitManager(String baseUrl) {

        retrofit = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .client(buildOkhttpClient())
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())
                .build();

    }

    private OkHttpClient buildOkhttpClient() {

        OkHttpClient client = new OkHttpClient.Builder()
                .readTimeout(5000, TimeUnit.MILLISECONDS)
                .writeTimeout(5000, TimeUnit.MILLISECONDS)
                .connectTimeout(5000, TimeUnit.MILLISECONDS)
                .build();

        return client;
    }

    public  T create(Class Clazz) {

        return retrofit.create(Clazz);

    }
}

登录的Api —— ILoginApi：

package com.example.mvpretrofitrxjava.mvp.view.iview;

import com.example.mvpretrofitrxjava.mvp.model.bean.LoginBean;

import io.reactivex.Observable;
import retrofit2.http.GET;
import retrofit2.http.Query;

/**
 * Created by DELL on 2018/7/11.
 */

public interface ILoginApi {

    @GET("user/login")
    Observable login(@Query("mobile") String mobile, @Query("password") String password);

}

登录回调的接口 —— ILoginView：

package com.example.mvpretrofitrxjava.mvp.view.iview;

import com.example.mvpretrofitrxjava.mvp.model.bean.LoginBean;

/**
 * Created by DELL on 2018/7/11.
 */

public interface ILoginView {

    void onLoginSuccess(LoginBean loginBean);

    void onLoginFailed(String error);

}

随后就是Model层 —— LoginModel：

package com.example.mvpretrofitrxjava.mvp.model;

import com.example.mvpretrofitrxjava.mvp.model.bean.LoginBean;
import com.example.mvpretrofitrxjava.mvp.view.iview.ILoginApi;
import com.example.mvpretrofitrxjava.utils.RetrofitManager;

import io.reactivex.Observable;

/**
 * Created by DELL on 2018/7/11.
 */

public class LoginModel {

    public Observable login(String mobile, String password) {

        return RetrofitManager.getDefault().create(ILoginApi.class).login(mobile, password);

    }

}

Presenter层 —— LoginPresenter：

package com.example.mvpretrofitrxjava.mvp.presenter;

import com.example.mvpretrofitrxjava.mvp.model.LoginModel;
import com.example.mvpretrofitrxjava.mvp.model.bean.LoginBean;
import com.example.mvpretrofitrxjava.mvp.view.iview.ILoginView;

import io.reactivex.Observable;
import io.reactivex.Observer;
import io.reactivex.android.schedulers.AndroidSchedulers;
import io.reactivex.disposables.Disposable;
import io.reactivex.schedulers.Schedulers;

/**
 * Created by DELL on 2018/7/11.
 */

public class LoginPresenter {

    private LoginModel loginModel;
    ILoginView mILoginView;

    public LoginPresenter(ILoginView loginView) {

        mILoginView = loginView;
        loginModel = new LoginModel();

    }

    public void login(String mobile, String password) {

        loginModel.login(mobile, password)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Observer() {
                    @Override
                    public void onSubscribe(Disposable d) {

                    }

                    @Override
                    public void onNext(LoginBean loginBean) {
                        if (mILoginView != null) {
                            mILoginView.onLoginSuccess(loginBean);
                        }
                    }

                    @Override
                    public void onError(Throwable e) {
                        if (mILoginView != null) {
                            mILoginView.onLoginFailed(e.toString());
                        }
                    }

                    @Override
                    public void onComplete() {

                    }
                });
    }

}

最后是MainActivity中的代码：

package com.example.mvpretrofitrxjava.mvp.view.activity;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Toast;

import com.example.mvpretrofitrxjava.R;
import com.example.mvpretrofitrxjava.mvp.model.bean.LoginBean;
import com.example.mvpretrofitrxjava.mvp.presenter.LoginPresenter;
import com.example.mvpretrofitrxjava.mvp.view.iview.ILoginView;

public class MainActivity extends AppCompatActivity implements ILoginView {

    private LoginPresenter presenter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        presenter = new LoginPresenter(this);
    }

    public void login(View view) {

        presenter.login("15201161615", "123456");

    }

    @Override
    public void onLoginSuccess(final LoginBean loginBean) {

        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(MainActivity.this, "登录成功" + loginBean.getData().getMobile(), Toast.LENGTH_SHORT).show();
            }
        });

    }

    @Override
    public void onLoginFailed(final String error) {

        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                Toast.makeText(MainActivity.this, "登录失败" + error, Toast.LENGTH_SHORT).show();
            }
        });

    }
}

写在最后：只是简单的利用MVP+Retrofit+RxJava框架实现了登录功能，不喜勿喷！！！
