adapter中数据修改了如何更新

//点赞功能异步请求接口实现

TipOffBean.class.getSimpleName());

return obj;
}

}
@Override

super.onResult(what, result);

Result<TipOffBean> re2 = (Result<TipOffBean>) result;
if(re2.getType() == 1){
showText("点赞成功！");

}
showText(re2.getMsg());

}


}
}
如何将点赞后的数据holder.dz_id.setText(bean.getPraise_times());这个的值如何修改为最新数据

[一不小心_]

listview在数据更新后，调用adapter.notifyDataSetchanged,textview你得手动重新赋值

[码猿]

就是重新赋值这一块不太会，该怎么做
