Fiori application 内的View 之间的导航
作者：互联网
1: 根据template创建一个Free style的 Fiori application。 https://www.cnblogs.com/liyafei/p/15742879.html
创建两个View和两个controller。提供json文件作为数据源。
2： 给view 添加 table 和column. https://www.cnblogs.com/liyafei/p/15748430.html
View1.xml
<mvc:View
controllerName="hansentestnavigation.controller.View1" //指定controller
xmlns:mvc="sap.ui.core.mvc" //指定使用的 component或者framework, 并给一个别名。
displayBlock="true"
xmlns="sap.m"
>
<Shell id="shell">
<App id="app">
<pages>
<Page id="page" title="{i18n>title}">
<content>
<Table class="sapUiSizeCompact" id="table1" includeItemInSelection="true" items="{path: 'DataModel>/Objects'}" mode="MultiSelect"
selectionChange="onselectionChange"> //id指定id, path指定数据源，从哪个datamodel中哪个字段json object. selectionChange 定义一个事件 onselectionchange
<columns> // 指定列。
<Column>
<Label text="Product Name"/>
</Column>
<Column>
<Label text="Supplier"/>
</Column>
<Column>
<Label text="Price"/>
</Column>
<Column>
<Label text="Units Ordered"/>
</Column>
</columns>
<ColumnListItem press="onPress" type="Navigation"> // 指定onPress事件，指定类型为导航。
<Text text="{DataModel>Name}"></Text> 指定从哪个datamodel获取值，DataModel该名字应该和controller 中的datamodel名字相同。
<Text text="{DataModel>Supplier}"></Text>
<Text text="{DataModel>Price}"></Text>
<Text text="{DataModel>Units}"></Text>
</ColumnListItem>
</Table>
</content>
</Page>
</pages>
</App>
</Shell>
</mvc:View>
View2.xml
<mvc:View
controllerName="hansentestnavigation.controller.View2" //指定controller2， 如果不指定，该controll将不能在前端页面加载出来。
xmlns:mvc="sap.ui.core.mvc"
displayBlock="true"
xmlns="sap.m"
>
<Shell id="shell">
<App id="app">
<pages>
<Page id="page2" navButtonPress="onNavBack" showNavButton="true" title="Tableview2"> //指定一个事件 onNavBack
<content>
<Table class="sapUiSizeCompact" id="abc" items="{path: 'navigationModel>/Objects'}"> // 指定model
<columns>
<Column width="11rem">
<Label text="Product Name"/>
</Column>
<Column width="11rem">
<Label text="Supplier"/>
</Column>
<Column hAlign="End" width="6rem">
<Label text="Price"/>
</Column>
<Column hAlign="End" width="15rem">
<Label text="Units Ordered"/>
</Column>
</columns>
<ColumnListItem press="onPress" type="Navigation">
<Text text="{navigationModel>Name}"></Text>
<Text text="{navigationModel>Supplier}"></Text>
<Text text="{navigationModel>Price}"></Text>
<Text text="{navigationModel>Units}"></Text>
</ColumnListItem>
</Table>
</content>
</Page>
</pages>
</App>
</Shell>
</mvc:View>

4： component.js 。 该js文件会加载一些component。
sap.ui.define([

"sap/ui/Device",
"hansentestnavigation/model/models",
"sap/ui/model/json/JSONModel" //初始化json model

"use strict";

metadata: {
manifest: "json"
},
/**
* The component is initialized by UI5 automatically during the startup of the app and calls the init method once.
* @public
* @override
*/
init: function () {
// call the base component's init function
UIComponent.prototype.init.apply(this, arguments);
// enable routing
this.getRouter().initialize(); // 初始化路由。
// set the device model
this.setModel(models.createDeviceModel(), "device"); // 调用model.js 文件，设置device model.
}
});
}
);
model.js

5: View1.controller.js

});
},

});
View2.controller.js
sap.ui.define([
"sap/ui/core/mvc/Controller",
"sap/ui/model/json/JSONModel",
"sap/ui/core/routing/History"
],
/**
