            ButterKnife.bind(this, view);

    }
}

代码如上,本人使用了代码

 
         adapter.bind(illegallist);
         adapter.notifyDataSetChanged();

获取bind()方法里的Log,发现list是改变了的,但是notifyDataSetChanged()无效。
求高手帮助!

listView的数据源要保持唯一 ,简单的说,你bind()的时候,传入的list必须是同一个对象(指向同一个地址).

recycleview 的刷新 不建议你直接调用
 notifyDataSetChanged

, 建议你看下最新的一个谷歌最近更新了Support Library 24.2.0,而DiffUtil就是在这个版本添加的一个工具类。
使用这个来刷新界面最好

更新时,在设置一次adpater

虽然没有亲测,但貌似一楼是对的,绑定不是同一个list 意思就是你 bind方法不要对 list进行重新赋值,首次绑定数据可以赋值一次,以后刷新应该直接刷新就可以了,不必再赋值。
