Sencha触摸面板内的2个列表

Question

Have a pretty common task to do where I need a search form above a list to display the results, the problem is that the list is not showing the results, the store and the proxy work correctly because when I use firebug to locate the list items the list always have height of 0px.

I have already searched and the common ways to workaround this is to use a fit layout, but using that on the parent panel makes all look small as if the width used was 10px.

I cant set a fixed height because I want the list to fill the remaining space, and neither the flex option cause that stretches the search form when I want that to use the default size of the buttons and input fields.

Here is the config Im using on the view

Ext.define('MyApp.view.search.Search', {
extend:'Ext.navigation.View',
xtype: 'search_view',
config:{
    items:[
        {
            fullscreen:true,
            scroll:false,
            xtype:'panel',
            title:'Search',
            items:[
                {
                    xtype:'searchfield',
                    name:'search',
                    label:'Search',
                },
                {
                    xtype:'container',
                    layout:'hbox',
                    width:'100%',
                    margin:'3 0 0 0',
                    defaults:{
                        flex:1
                    },
                    items:[
                        {
                            xtype:'selectfield',
                            options:[
                                {text:'Option 1', value:'opt1'},
                                {text:'Option 2', value:'opt2'}
                            ]
                        },
                        {
                            xtype:'button',
                            text:'Search',
                            action:'search'
                        }
                    ]   
                },
                {
                    xtype:'list',
                    itemTpl:['{title}'],
                    onItemDisclosure:true,
                    plugins:[
                        { xclass: 'Ext.plugin.ListPaging' }
                    ]
                }

            ]
        },
    ],      
}
});

This image describes what Im trying to achieve, I took this screenshot by setting manually a height to the list container, as you can see it works the problem is that the list height doesn't fill the space below the form by default.

This is what I ended up doing to solve this, it's more of a workaround since I had to change the layout to only have the list in it, and use toolbars for the search options, this way the toolbar controls only use the minimum height they need to draw themselves correctly.

Ext.define('MyApp.view.search.Search', {
extend:'Ext.Container',
xtype: 'search_view',
config:{
    fullscreen:true,
    layout:'card'
    items:[
        {
            xtype:'toolbar',
            docked:'top',
            items:[
                {
                    xtype:'searchfield',
                    name:'search',
                    flex:6
                },
                {
                    xtype:'button',
                    action:'search',
                    iconCls:'search',
                    iconMask:true,
                    ui:'simple',
                    flex:1
                }
                    ]
        },
        {
            xtype:'toolbar',
            docked:'top',
            items:[
                {
                    xtype:'selectfield',
                    flex:1,
                    options:[
                        {text:'Option 1', value:'opt1'},
                        {text:'Option 2', value:'opt2'}
                    ]
                }
            ]
        },
        {
             xtype:'list',
             itemTpl:['{title}'],
             onItemDisclosure:true,
             plugins:[
                 { xclass: 'Ext.plugin.ListPaging' }
             ]

        },
        ],      
    }
});

As you can see I have two toolbars docked at the top, and the list filling the whole layout. Here is a screenshot of how it looks now.

Thanks for your time.

你尝试过将容器布局设置为“适合”吗？基本上它会使用所有剩余的可用高度，这里有一个关于sencha touch布局的精彩指南： http ： //docs.sencha.com/touch/2-0/从文档中直接＃！/ guide / layouts ！

Panel should have vbox layout, list should have fit layout and set flex option.

As seen if example bellow, if flex value is not set to a button, it should get default size.

From the documentation :

Flexing means we divide the available area up based on the flex of each child component...

Here is an example:

Ext.define('MyApp.view.Main', { extend: 'Ext.tab.Panel',

config: {
  tabBarPosition: 'bottom',

  items: [
    {
      title: 'Welcome',
      iconCls: 'home',

      html: [
        "Some content"
      ].join("")
    },

    {
      title: "About",
      iconCls: 'star',
      layout: "vbox", // this card has vbox layout

      items: [{
        docked: 'top',
        xtype: 'titlebar',
        title: 'List'
      },

      {
        xtype: "list",
        layout: "fit", // take as much space as available
        flex: 1, // define flex
        data: [
          {name: 'Jamie Avins',  age: 100},
          {name: 'Rob Dougan',   age: 21},
          {name: 'Tommy Maintz', age: 24},
          {name: 'Jacky Nguyen', age: 24},
          {name: 'Ed Spencer',   age: 26}
        ],
        itemTpl: '{name} is {age} years old'
      },

      {
        xtype: 'button',
        text: "Button"
      }

      ]
    }
  ]
}

});
