我从NativeScript市场代码示例here学习NativeScript。我试图用下面的自定义选项卡创建一个TabView，但我认为我对路由器配置感到困惑。我的home.component.html内容不会显示在tabview中，它始终显示为空。知道为什么吗？

我有以下文件：

• main.component.html
• home.component.html
• profile.component.html

在我的app-routing.module.ts中，：

export const routes: Routes = [
    { 
        path: "",redirectTo: "/main/(homeOutlet:home//profileOutlet:profile)",pathMatch: "full" 
    },{
        path: "main",component: MainComponent,runGuardsAndResolvers: 'always',canactivate: [AuthGuard],children: [
            { path: "home",component: HomeComponent,outlet: "homeOutlet"},{ path: "profile",component: ProfileComponent,outlet: "profileOutlet"}
        ]

    }
];

main.component.html：

<!-- https://docs.nativescript.org/angular/core-concepts/angular-navigation.html#page-router-outlet -->
<GridLayout columns="*,*,*" rows="*,auto,auto" class="page" >

  <TabView col="0" row="0" colSpan="3" rowSpan="2" [(ngModel)]="tabIndex"
      width="100%" androidTabsPosition="bottom" (loaded)="onTabViewLoaded($event)">

      <page-router-outlet *tabItem="{title: 'profile'}" name="profileOutlet">
      </page-router-outlet>
      <page-router-outlet *tabItem="{title: 'home'}" name="homeOutlet">
      </page-router-outlet>

  </TabView>

  <android>
      <StackLayout col="0" row="2" colSpan="3" class="bottom-bar-background"
          verticalAlignment="bottom"></StackLayout>

  <GridLayout col="0" row="2" height="48" class="bottom-bar-btn" (tap)="changetabIndex(0)">
      <Image [src]="getIconSource('profile',0)" class="image"
          verticalAlignment="center" (loaded)="onFavIconLoaded($event)"></Image>
  </GridLayout>

  <android>
      <StackLayout col="1" row="2" rowSpan="2" class="btn-square btn-cta m-b-20 over"
          (tap)="changetabIndex(1)">
          <GridLayout class="btn-cta-background" [class.active]="tabIndex === 1"
              borderRadius="12">
              <Image [src]="getIconSource('portalest',1)" class="image"></Image>
          </GridLayout>
      </StackLayout>

  <GridLayout col="2" row="2" height="48" class="bottom-bar-btn" (tap)="changetabIndex(2)">

          verticalAlignment="center"></Image>
