使用方法：

new DialogUtils(MainActivity.this, R.layout.dialog_view) {            @Override            public void initLayout(ViewHepler hepler, final Dialog dialog) {                //加载文字                hepler.setText(R.id.tv_close, "提示：");                hepler.setText(R.id.tv_hint, "内容test内容test内容test内容test内容test");                // 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() {                    @Override                    public void doClickAction(View v) {                        dialog.dismiss();                    }                });                hepler.setViewClick(R.id.tv_ok, new ViewHepler.ViewClickCallBack() {                    @Override                    public void doClickAction(View v) {                        Toast.makeText(MainActivity.this,"确定",Toast.LENGTH_SHORT).show();                    }                });            }        };
