使用示例js

 1 Ext.define('app.view.new.List', {
 2     alternateClassName: 'newList',
 3     extend: 'ux.SimpleList',
 4     requires: ['app.view.new.Info'],
 5     xtype: 'newList',
 6     config: {
 7         store: 'newList',
 8         cls: 'list', //自定义css
 9         itemTpl: new Ext.XTemplate('<div class="left w20"><div class="img" style="background: url({litpic}) no-repeat center;background-size: 100%;"></div></div>', '<div class="right w80"><div class="row">{title}</div><div class="row grayF">{time}</div></div>')
10     }
11 });

控制器js

 1 /*
 2 *新闻类
 3 */
 4 Ext.define('app.controller.New', {
 5     extend: 'Ext.app.Controller',
 6     config: {
 7         models: ['New'],
 8         stores: ['NewList'],
 9         views: ['new.List'],
10         refs: {
11             newList: 'newList'
12         },
13         control: {
14             //新闻列表
15             newList: {
16                 initialize: function (list) {
17                     MyUtil.showListByParams('newList', MyUtil.newParams, MyUtil.isNewLoad);
18                 },
19                 //itemtap事件被用来处理检测是否在编辑状态，所以这里使用itemsingletap而不能使用itemtap
20                 itemsingletap: function (list, index, target, record, e) {
21                     this.redirectTo('newInfo');
22                     MyUtil.showInfo(record, 'newInfo', 'NewInfo.ashx', 'body', {
23                         id: record.data.id
24                     });
25                 },
26                 //结束多选事件触发
27                 simpleSuccess: function (list, items, ids, type) {
28                     console.log(ids);
29                 }
30             }
31         }
32     }
33 });

效果：

单击

长按

确定后触发simpleSuccess事件，输出ids
