调用

HttpNetUtils：

public class Model { public void getData( final IPresenter iPresenter) { //调用工具类，得到被观察者 final HttpNetUtils instance = HttpNetUtils. getInstance() ; ApiService service = instance.getService() ; Flowable<MessageBean<LeftBean>> data = service.getData() ; left.subscribeOn(Schedulers. io()) .observeOn(AndroidSchedulers. mainThread()) //创建被观察者对象 .subscribe( new DisposableSubscriber<MessageBean<LeftBean>>() { @Override public void onNext(MessageBean<LeftBean> leftBeanMessageBean) {

                     iPresenter.success(leftBeanMessageBean);

} @Override public void onError(Throwable t) { } @Override public void onComplete() { } }) ; }}
