我打算在Android Studio中使用rxjava进行改造。实际上我遵循了 https://code.tutsplus.com/tutorials/getting-started-with-retrofit-2--cms-27792教程这就是我所做的一切：

compile 'com.android.support:appcompat-v7:25.1.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.squareup.retrofit2:retrofit:2.2.0'
    compile 'com.google.code.gson:gson:2.8.0'
    compile 'com.squareup.retrofit2:converter-gson:2.2.0'
    compile 'com.android.support:recyclerview-v7:25.1.0'
    compile 'com.squareup.retrofit2:adapter-rxjava2:2.2.0'
    compile 'io.reactivex.rxjava2:rxjava:2.0.9'
    compile 'io.reactivex:rxandroid:1.2.1'
    compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
    compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'

我创建了Retrofit客户端和Interface订阅方法。说不能解决

mService.getAnswer().subscribeOn(Schedulers.io()).observeOn(AndroidSchedulers.mainThread())
             .subscribe(new Subscriber<SOAnswersResponse>() {
                            @Override
                            public void onCompleted() {

                            }

                            @Override
                            public void onError(Throwable e) {

                            }

                            @Override
                            public void onNext(SOAnswersResponse soAnswersResponse) {

                            }


       }
         );

我在主要活动中导入了此内容：

import android.os.Bundle;
import android.support.v7.widget.DividerItemDecoration;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;

import android.widget.Toast;
