RetrofitUtil

BaseObservaer

public abstract class BaseObserver implements Observer {
    public void onSubscribe(Disposable d) {

    }

    /**
     * 执行成功的方法
     *
     * @param s
     */
    @Override
    public void onNext(String s) {
        onSuccess(s);
    }

    /**
     * 执行失败的方法
     *
     * @param e
     */
    @Override
    public void onError(Throwable e) {
        onFailed(e);
    }

    @Override
    public void onComplete() {

    }

    public abstract void onSuccess(String s);

    public abstract void onFailed(Throwable e);
}

Model操作

 //获取工具类对象
        RetrofitUtil.getRetrofitUtil().create(ILoad.class).showBanner()
                //订阅者
                .subscribeOn(Schedulers.io())
                //观察者
                .observeOn(AndroidSchedulers.mainThread())
                //订阅对象
                .subscribe(new BaseObserver() {
                    @Override
                    public void onSuccess(String s) {
                        bannerModelCallBack.getSuccess(实体类bean对象);
                    }

                    @Override
                    public void onFailed(Throwable e) {
                        bannerModelCallBack.getFaid(e);
                    }
