使用OKHttp处理Volley的底层HTTP请求

1) 导入Volley（目前没有官方的jar包，需要自己下载源码编译）

2) 导入OkHttp，okhttp-urlconnection

3) 创建OkHttpStack

public class OkHttpStack extends HurlStack {
    private OkHttpClient okHttpClient;

    /**
     * Create a OkHttpStack with default OkHttpClient.
     */
    public OkHttpStack() {
        this(new OkHttpClient());
    }

    /**
     * Create a OkHttpStack with a custom OkHttpClient
     *
     * @param okHttpClient Custom OkHttpClient, NonNull
     */
    public OkHttpStack(OkHttpClient okHttpClient) {
        this.okHttpClient = okHttpClient;
    }

    @Override
    protected HttpURLConnection createConnection(URL url) throws IOException {
        OkUrlFactory okUrlFactory = new OkUrlFactory(okHttpClient);
        return okUrlFactory.open(url);
    }
}

4) 创建Volley队列

Volley.newRequestQueue(context, new OkHttpStack());
