private String bg_url;

public ThemeListAdapter(List<ThemeEntity.DataEntity> list, Context context) {
super(list,context);

imageLoader = new ImageLoader(MyApp.getInstance().getRequestQueue(), new ImageLoader.ImageCache() {
//定义内存缓存

//获取图片地址

//设置图片

ivImage = (ImageView) convertView.findViewById(R.id.ivImage);
}
}
