                // 加载Resource图片
                hepler.setImageResource(R.id.img_cancel,R.drawable.ic_cancel);
                //加载网络图片
                hepler.setImageByUrl(R.id.img_content,"http://img3.imgtn.bdimg.com/it/u=2730707097,3811913056&fm=26&gp=0.jpg");

                //加载点击事件
                hepler.setViewClick(R.id.img_cancel, new ViewHepler.ViewClickCallBack() {
                    @Override
                    public void doClickAction(View v) {
                        dialog.dismiss();
                    }
                });
                hepler.setViewClick(R.id.tv_cancel, new ViewHepler.ViewClickCallBack() {
