自己写的RxJava和Retrofit结合

依赖:

compile 'io.reactivex.rxjava2:rxandroid:2.0.1'
compile 'io.reactivex.rxjava2:rxjava:2.0.1'
compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'

ApiService:

public interface ApiService {
    @GET
    io.reactivex.Observable get(@Url String url);
}

Util:

public class RetrofitUtil {
    private ApiService apservice;
    private static volatile RetrofitUtil retrofitutils;
