RxJava与RetroFit的封装

1.在Build.gradler文件中搭建环境
 2.自定义RetroFit网络请求接口APISever
 3.对RetroFit网络进行封装RetfitFactory
 4.使用适配器设计模式，简化RetroFit请求代码,BaseObserver

 5.完善

依赖文件
    /*RxJava与RxAndroid的依赖*/
    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
    compile 'io.reactivex.rxjava2:rxjava:2.1.0'

    /*Retrofit与RxAndroid配置依赖*/
    compile 'com.squareup.retrofit2:retrofit:2.3.0'
    compile 'com.squareup.retrofit2:adapter-rxjava2:2.3.0'

    /*使Retrofit的转化器自定义完成数据的转化
    * 就是我们可以接口中少写一些bean类
    * */
    compile 'com.squareup.retrofit2:converter-scalars:+'
    /** 日至拦截器 */
    compile 'com.squareup.okhttp3:logging-interceptor:3.9.0'
    /*gson解析*/

    compile 'com.google.code.gson:gson:2.8.1'
