QuickAdapter 的创建
来源：互联网 发布：外贸网络销售平台 编辑：程序博客网 时间：2024/05/29 13:40
详解：http://blog.csdn.net/lmj623565791/article/details/44014941- 这里是只支持一种布局的Quick，要使用多种布局，参考以上链接,
- 注意：由于setImageUrl()方法会根据图片的url加载图片，
- 需要导入Picasso包
- 使用方法 ： 一般情况下，只需要创建适配器QuickAdapter，
- adapter = new QuickAdapter< SearchShop>(context, R.layout.recommend_shop_list_item) {
@Override
protected void convert(BaseAdapterHelper helper, SearchShop shop) {
helper.setText(R.id.name, shop.getName())
.setText(R.id.address, shop.getAddr())
.setImageUrl(R.id.logo, shop.getLogo()); // 自动异步加载图片
}
}; - SearchShop 封装数据的对象，
- 然后加载数据， List < SearchShop> list,调用 adapter.addAll(list);更新数据源 6.
