2.清单文件中注册初始化
  初始化:x.Ext.init(this);
         x.Ext.setDebug(BuildConfig.DEBUG); // 是否输出debug日志, 开启debug会影响性能.//上线后参数设为false 将debug关掉

3.使用utils3加载网络图片
   x.image().bind(image, "https://p.ssl.qhimg.com/t01d15b1004b11cb0a7.jpg");

4.使用utils3加载本地动态图片
  1)创建assets文件 存放动态图片
  2)ImageOptions imageOptions = new ImageOptions.Builder()
                        .setIgnoreGif(false)
                        .setImageScaleType(ImageView.ScaleType.CENTER).build();
                x.image().bind(image, "assets://d.gif", imageOptions);

5.使用utils3加载网络数据
  RequestParams requestParams=new RequestParams("http://apicloud.mob.com/v1/cook/category/query?key=1d11949556a24");
                x.http().get(requestParams, new Callback.CommonCallback<String>() {
                    @Override
                    public void onSuccess(String result) {
                        Log.d("sss","onSuccess::"+result);

                    }

                    @Override
                    public void one rror(Throwable ex, boolean isOnCallback) {
                        Log.d("sss","onError::"+ex.getMessage());
                    }

                    @Override
                    public void onCancelled(CancelledException cex) {
                        Log.d("sss","onCancelled::"+cex.getMessage());
                    }

                    @Override
                    public void onFinished() {
                        Log.d("sss","onFinished::");

                    }
                });
