我知道我需要使用Dataview来创建列表。但我不知道如何使用dataview创建这样的布局。任何帮助都将不胜感激。

以下是创建布局所需的代码

Ext.Loader.setConfig({
    enabled: true
});

Ext.application({
    launch: function () {
        Ext.define('MyListItem', {
            extend: 'Ext.dataview.component.DataItem',
            requires: ['Ext.Button'],
            xtype: 'mylistitem',
            config: {
                labelPanel:{
                    itemId:'labelpanel',
                    layout:'hbox',
                    defaults:{
                        //flex:1,
                        xtype:'label'
                    }
                },
                fnameLabel: true,
                lnameLabel: {
                    style:'margin-left:5px'    
                },                
                horizontalPanel: {
                    layout: 'hbox',
                    defaults:{
                        xtype:'button',
                        flex:1
                    },
                    items: [{
                        text: 'First Name',
                        btnId:1
