案例：实现原生登录注册和个人中心模块。（100分）

需求分析：

1. 新建一个工程，命名为UserCenter

2. 实现如图登录注册模块和个人中心模块，登录成功后跳转到个人中心页面；

3. 第二次进入自动登录；

  

效果图描述：

1. 使用RxJava结合Retrofit+OkHTTP封装工具类请求数据，使用MVP分层，进行原生登录,注册,个人信息页；

2. 使用Fresco加载图片，设置用户头像（图片上传或拍照）。

3. 实现如图登录注册模块和个人中心模块，登录成功后跳转到个人中心页面；

    第二次使用 SharedPreferences保存信息 进入自动登录；

首先在项目Model的build.gradle里面导入依赖

//butterknife在Studio3.0版本上需使用以下8.8.1版本（下面2行代码都要加）
compile 'com.jakewharton:butterknife:8.8.1'
annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'

compile 'com.facebook.fresco:fresco:1.5.0'

//由于Retrofit是基于OkHttp，所以还需要添加OkHttp库依赖
compile 'com.squareup.retrofit2:retrofit:2.3.0'
compile 'com.squareup.retrofit2:converter-scalars:2.3.0'
compile 'com.squareup.okhttp3:okhttp:3.9.0'
//如果采用了 Gson 解析，需要在 Gradle加入retrofit2类库中的gson依赖
compile 'com.squareup.retrofit2:converter-gson:2.3.0'     //较新版本

compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex.rxjava2:rxjava:2.1.7'
compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'

新建MyApplication 继承Application ,并在清单文件中配置，添加网络权限

import android.app.Application;
import com.facebook.drawee.backends.pipeline.Fresco;

/**
 * 用于全局配置初始化异步加载类
 */
public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();

        //  用于全局配置初始化Fresco 图片加载
        Fresco.initialize(this);
    }
}

 <application

android :name= ".app.MyApplication"

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

请求网络获得的数据生成实体类(自己根据接口生成，这里不再重写)

1. 登录信息 LoginBean

用户登录信息 http://120.27.23.105/user/login?mobile=18631090582&password=888888

2. 注册信息 RegBean

用户注册数据  http://120.27.23.105/user/reg?mobile=18631090582&password=888888

3.个人信息  PersonInfoBean

个人信息数据  http://120.27.23.105/user/getUserInfo?uid=100

新建网络请求接口类GetDataInterface

import io.reactivex.Observable;
import retrofit2.http.FieldMap;
import retrofit2.http.FormUrlEncoded;
import retrofit2.http.GET;
import retrofit2.http.POST;
import retrofit2.http.Query;

/**
 * 网络接口数据的请求类
 */
public interface GetDataInterface {

    //注册的接口
    //https://www.zhaoapi.cn/user/reg?mobile=18631090582&password=888888
    @FormUrlEncoded
    @POST("/user/reg")
    Observable reg(@FieldMap Map map);

    //登录的接口
    //https://www.zhaoapi.cn/user/login?mobile=18631090582&password=888888
      @FormUrlEncoded
    @POST("/user/login")
    Observable login(@FieldMap Map map);

    //个人中心接口：
    //https://www.zhaoapi.cn/user/getUserInfo?uid=100
    @GET("/user/getUserInfo")
    Observable person(@Query("uid") int uid);
}

自定义 Retrofit+RxJava+OkHttp封装类请求接口数据

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

/**
 * Retrofit+Rxjava+OkHttp 单例模式+双重锁模式 封装类
 */
public class RetrofitUnitl {
    private Retrofit mRetrofit;
    private String baseUrl;
    OkHttpClient client;
    private static RetrofitUnitl mRetrofitManager;
    private RetrofitUnitl(String baseUrl,OkHttpClient client){
        this.baseUrl=baseUrl;
        this.client=client;
        initRetrofit();
    }

    //单例模式+双重锁模式 封装方法
    public static synchronized RetrofitUnitl getInstance(String baseUrl,OkHttpClient client){
        if (mRetrofitManager == null){
            mRetrofitManager = new RetrofitUnitl(baseUrl,client);
        }
        return mRetrofitManager;
    }

    //实例化Retrofit请求
    private void initRetrofit() {
        mRetrofit = new Retrofit.Builder()
                .baseUrl(baseUrl)
                .addConverterFactory(GsonConverterFactory.create())
                .addCallAdapterFactory(RxJava2CallAdapterFactory.create())

    }

    //封装泛型方法
    public <T> T setCreate(Class<T> reqServer) {
        return mRetrofit.create(reqServer);

自定义添加公共请求参数的拦截器

import java.io.IOException;
import okhttp3.Interceptor;
import okhttp3.Request;
import okhttp3.Response;

//自定义添加公共请求参数的拦截器
public class LoggingInterceptor implements Interceptor {
  @Override public Response intercept(Chain chain) throws IOException {
    Request request = chain.request();

    //开始响应的时间
    long t1 = System.nanoTime();
    //执行请求，返回响应的数据
    Response response = chain.proceed(request);
    //请求结束，响应返回
    long t2 = System.nanoTime();

    //响应的耗费时间
    System.out.println(" this request  url  " + response.request().url() + "  "  + (t2 - t1)/1000000);

    return response;
  }
}

自定义存取数据的SharedUtils

import android.content.Context;
import android.content.SharedPreferences;
import android.content.SharedPreferences.Editor;

public class SharedUtils {
   static SharedPreferences preferences;
   static String  File = "data";
   
   //保存数据的方法
   public static void savaBooleanData(Context context, String key,boolean value){
      if (preferences == null) {
         preferences = context.getSharedPreferences(File, Context.MODE_PRIVATE);
      }
      
      //获取编辑器对象
      Editor editor = preferences.edit();
      editor.putBoolean(key, value).commit();
   }
   
   //获取数据的方法
   public static boolean getBooleanData(Context context, String key,boolean defValue){
      if (preferences == null) {
         preferences = context.getSharedPreferences(File, Context.MODE_PRIVATE);
      }
      
      return preferences.getBoolean(key, defValue);
   }
}
