我是 Sencha Touch 2 的新手。我正在为 Android 2.3.4 构建一个 PhoneGap + Sencha Touch 2 应用程序。我完成了我的应用程序的开发。在测试应用程序时，我发现我使用的导航视图在点击披露项时响应非常慢。我正在使用列表容器视图、列表视图和编辑器视图。下面给出了它们的代码。下面的代码工作正常，但在点击披露项时，事件编辑器视图会在 10 秒后显示，有时我什至不知道它是否被点击。
所以我在两件事上需要帮助：1.）当我点击披露项目时，我应该显示屏蔽以知道我至少点击了它 2.）或者加快事件编辑器视图的显示
列表容器视图：
Ext.define('Sample.view.ListContainer', {
extend: 'Ext.NavigationView',
xtype:'listContainer',
id: 'idListContainer',
config: {
id:'idIncidentListContainer',
items:[
{
xtype:"incidentsList",
cls: "clsHeader"
}
]
}
});
列表显示：
Ext.define("Sample.view.IncidentsList", {
extend: "Ext.Panel",
xtype: 'incidentsList',
id: 'idIncidentList',
requires:[
'Ext.dataview.List',
'Ext.data.proxy.Memory',
'Ext.data.Store',
],
alias:'widget.incidentslist',

},
{ xtype: 'spacer'},
{ xtype: 'title' ,

},
]
},
{
xtype: "list",

itemId:"incidentsList",
id:"inclist",
loadingText: "Loading Incidents...",
emptyText: "<div class=\"empty-text\">No incidents found.</div>",
onItemDisclosure: true,

listeners: [

]
},
initialize: function() {
this.callParent(arguments);
var getLoginData = localStorage.getItem('userData');
var parseData = JSON.parse(getLoginData);
var fname = parseData[0].FIRST_NAME;
var getIncidentData = localStorage.getItem('userIncidentData');
var parseIncidentData = JSON.parse(getIncidentData);
Ext.getCmp("idIncidentsListTitle").setTitle("Welcome, " + fname);
Ext.getStore("IncidentStore").setData(localStorage.userIncidentData).load();
},
onIncidentsListDisclose: function (list, record, target, index, evt, options) {
console.log("editIncidentCommand");
/*var list = Ext.getCmp('idIncidentList');
list.setMasked({
xtype:'loadmask',
message:'Loading...'
});*/
this.fireEvent('editIncidentCommand', this, record);
}
});
编辑器视图：
Ext.define("Sample.view.IncidentEditor", {
extend: 'Ext.form.Panel',
xtype: 'incidentsEditor',
id:'incidentsEditorView',
alias: "widget.incidenteditorview",
config: {

},
],
},
initialize: function() {
var getLoginData = localStorage.getItem('userData');
var parseData = JSON.parse(getLoginData);
var fname = parseData[0].FIRST_NAME;
Ext.getCmp("idIncidentEditorTitle").setTitle("Welcome, " + fname);
//var list = Ext.getCmp('idIncidentList');
//list.unmask();
},
onIncidentsListDisclose: function (list, record, target, index, evt, options) {
console.log("editIncidentCommand");
this.fireEvent('editIncidentCommand', this, record);
}
});
控制器：
Ext.define("Sample.controller.Incidents", {
extend: "Ext.app.Controller",
config: {
refs: {
//lookup for views by xtype
incidentsListView:'incidentslist',
incidentEditorView: 'incidenteditorview',
incidentsList: 'incidentsList',
listContainer:'listContainer'
},
control: {
incidentsListView: {
//commands fired by the Incidents list container.
editIncidentCommand: "onEditIncidentCommand",
},
}
},
//Transitions
slideLeftTransition: { type: 'slide', direction: 'left' },
slideRightTransition: { type: 'slide', direction: 'right' },
//Helper function(generates random integer)
getRandomInt: function (min, max) {
return Math.floor(Math.random() * (max - min + 1)) + min;
},
//Function to get incident details and set them to incidentview
activateIncidentEditor: function (record) {
var incidentContainer = this.getListContainer();
var incidentEditorView = Ext.create("Sample.view.IncidentEditor");
incidentEditorView.setRecord(record); // load() is deprecated.
incidentContainer.push(incidentEditorView);
},
//on edit incident command
onEditIncidentCommand: function (list, record) {
this.activateIncidentEditor(record);
}
});
请帮帮我......提前谢谢......！！！
