Rxjava操作符zip

方法和参数：

public static <T1, T2, R> Observable<R> zip(Observable<? extends T1> o1, Observable<? extends T2> o2, final Func2<? super T1, ? super T2, ? extends R> zipFunction)

这里的第一个和第二个都是retrofit返回的两个Observable结果，我们需要把里面的内容取出来拼接成一个新的bean，用于之后的链式。

class GetRealTask extends Thread {//这里是因为我的项目需要轮询，所以新建一个线程，当然也可以用Rxjava的repeatWhen操作符实现更优雅。
    volatile boolean stop = false;
    public void run() {
        while (!stop) {
            getData();
            SystemClock.sleep(10*1000);
        }
    }

}

private void getData() {
    Observable
            .zip(PRRetrofit.getmInstance().getmPRService().getDetail(did1), PRRetrofit.getmInstance().getmPRService().getDetail(did2), new Func2<DeviceDetailBean, DeviceDetailBean, List<DeviceDetailBean.RealTimeParamsEntity>>() {
                @Override
                public List<DeviceDetailBean.RealTimeParamsEntity> call(DeviceDetailBean deviceDetailBean, DeviceDetailBean deviceDetailBean2) {
                    mRealTimeParamsList.clear();
                    String deviceName = deviceDetailBean.getDeviceName();
                    for (DeviceDetailBean.RealTimeParamsEntity bean : deviceDetailBean.getRealTimeParams()) {
                        bean.setPName(deviceName + "-" + bean.getPName());
                        mRealTimeParamsList.add(bean);
                    }
                    String deviceName2 = deviceDetailBean2.getDeviceName();
                    for (DeviceDetailBean.RealTimeParamsEntity bean2 : deviceDetailBean2.getRealTimeParams()) {
                        bean2.setPName(deviceName2 + "-" + bean2.getPName());
                        mRealTimeParamsList.add(bean2);
                    }
                    return mRealTimeParamsList;
                }
            })
            .subscribeOn(Schedulers.io())
            .unsubscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(new Subscriber<List<DeviceDetailBean.RealTimeParamsEntity>>() {
                @Override
                public void onCompleted() {
     
                }

                @Override
                public void onError(Throwable e) {
                     //处理错误异常

                }

                @Override
                public void onNext(List<DeviceDetailBean.RealTimeParamsEntity> deviceDetailBean) {                    
                    if (deviceDetailBean != null) {
                   //处理数据显示adapter更新等；
                    } else {
                        TUtil.t("无数据");
                    }
                }
            });
