在vendor\yiisoft\yii2\widgets路径下新增文件ListViewtest，将下列代码粘贴并保存

在视图模板中调用这个ListViewtest
<?php
use yii\widgets\ListViewtest;
?>
<?=ListViewtest::widget([
'layout' => "{items}\n{pager}",
'dataProvider' => $dataProvider,
'itemView' => '_test',//子视图
'itemView_top' => '_test1',//top模板
'num_top' => 1,//使用top模板的数目
'start_num' => 10,//从第几开始计数？默认0
//调用原模板（itemView模板，非itemView_top模板）时前后包夹标签
'front_moban' => [
'flag' => true, //开关，默认关
'tag_front' => '<front>', //前标签
'tag_back' => '</front>', //后标签
],
//每打印多少条数据的末尾，出现一次html标签
'extra' => [
'flag' => false, //开关，默认关
'tag' => '<hr>', //该标签
'num' => 5, //条数
]
//是否允许用div框住，默认否
'div_allowed' => true,
'options' => [ //该div的属性
'class' => null,
'id' => 'eee',
]
]);?>
