Retrofit2.0 android.os.NetworkOnMainThreadException解决方法

在使用Retrofit2.0中出现了android.os.NetworkOnMainThreadException异常，代码如下：

FamousInfoModel.getInstance(getActivity()).queryLookUp("人才",mCurrentPage)
                        .subscribeOn(Schedulers.io())
                        .observeOn(AndroidSchedulers.mainThread())
                        .subscribe(mSubscriber);

根据网上意思，是要起一个新线程，代码如下：

new Thread() {
            @Override
            public void run() {
                FamousInfoModel.getInstance(getActivity()).queryLookUp("人才",mCurrentPage)
                        .subscribeOn(Schedulers.io())
                        .observeOn(AndroidSchedulers.mainThread())
                        .subscribe(mSubscriber);
            }
        }.start();

运行没有问题，但总看着别扭，有没有更好的方式呢？结果是肯定的。Schedulers.io()改为Schedulers.newThread()即可。

FamousInfoModel.getInstance(getActivity()).queryLookUp("人才",mCurrentPage)
                .subscribeOn(Schedulers.newThread())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(mSubscriber);

当我们在自定义view里面请求数据时，上面的方法就不行了，如下

public class HomeSlideShowView extends FrameLayout {

    public HomeSlideShowView(Context context) {
        this(context, null);
    }

    public HomeSlideShowView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public HomeSlideShowView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        this.context = context;

        initView();
    }

    private void initView() {
        LayoutInflater.from(context).inflate(R.layout.layout_slideshow, this,
                true);
        dotLayout = (LinearLayout) findViewById(R.id.dotLayout);
        adverList = new ArrayList<>();

        imageViewsList = new ArrayList<>();
        dotViewsList = new ArrayList<>();

        viewPager = (ViewPager) findViewById(R.id.viewPager);
        viewPager.setFocusable(true);

        mAdapter = new MyPagerAdapter(adverList);
        viewPager.setAdapter(mAdapter);

        viewPager.setOnPageChangeListener(new MyPageChangeListener());

    }

    //此处省去...

    private void processData() {
        Log.d(TAG, "processData ");
        APIWrapper.getInstance().getBannerImages()
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(new Subscriber<JavaResponse<List<Advertisement>>>() {
                    @Override
                    public void onCompleted() {
                    }

                    @Override
                    public void onError(Throwable e) {
                    }

                    @Override
                    public void onNext(JavaResponse<List<Advertisement>> response) {
                        List<Advertisement> list = response.data;
                        mHandler.obtainMessage(FRESH_BANNER_DATA, list).sendToTarget();
                    }
                });

    }


}

android.os.NetworkOnMainThreadException异常出现时，.subscribeOn(Schedulers.newThread()) 与 .subscribeOn(Schedulers.io()) 总有个能解决问题。
