从页面导航后离子条消失

Question

我在 Ionic Angular 中使用登录组件。当我登录时，我重定向到选项卡模块。之后，选项卡显示 tab1 屏幕。问题是标签栏消失了。我不知道这怎么会发生。

app.routing.module.ts

import { NgModule } from '@angular/core';
import { PreloadAllModules, RouterModule, Routes } from '@angular/router';

const routes: Routes = [
  {
    path: '',
    loadChildren: () =>
      import('./login/login.module').then((m) => m.LoginPageModule),
    //import('./tabs/tabs.module').then((m) => m.TabsPageModule),
  },
  {
    path: 'login',
    loadChildren: () =>
      import('./login/login.module').then((m) => m.LoginPageModule),
  },
  {
    path: 'tabs',
    loadChildren: () =>
      import('./tabs/tabs.module').then((m) => m.TabsPageModule),
  },
  {
    path: 'tabs/tab1',
    loadChildren: () =>
      import('./tab1/tab1.module').then((m) => m.Tab1PageModule),
  },
  {
    path: 'tabs/tab2',
    loadChildren: () =>
      import('./tab2/tab2.module').then((m) => m.Tab2PageModule),
  },
  {
    path: 'tabs/tab3',
    loadChildren: () =>
      import('./tab3/tab3.module').then((m) => m.Tab3PageModule),
  },
  {
    path: 'edit-event',
    loadChildren: () =>
      import('./edit-event/edit-event.module').then(
        (m) => m.EditEventPageModule
      ),
  },
];
@NgModule({
  imports: [
    RouterModule.forRoot(routes, { preloadingStrategy: PreloadAllModules }),
  ],
  exports: [RouterModule],

export class AppRoutingModule {}

tabs-routing.module.ts

    component: TabsPage,
    children: [

        loadChildren: () =>
          import('../tab2/tab2.module').then((m) => m.Tab2PageModule),

      {
        path: 'tab3',
        loadChildren: () =>
          import('../tab3/tab3.module').then((m) => m.Tab3PageModule),
      },
      {
        path: '',
        redirectTo: '/tabs/tab1',
        pathMatch: 'full',
      },
    ],
  },
  {
    path: '',
    redirectTo: '/tabs/tab1',
    pathMatch: 'full',
  },
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
})
export class TabsPageRoutingModule {}

login-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

import { LoginPage } from './login.page';

const routes: Routes = [
  {
    path: '',
    component: LoginPage,
  },
  {
    path: 'tabs',
    loadChildren: () =>
      import('../tabs/tabs.module').then((m) => m.TabsPageModule),
  },
  {
    path: 'tab1',
    loadChildren: () =>
      import('../tab1/tab1.module').then((m) => m.Tab1PageModule),
  },
  {
    path: 'tab2',
    loadChildren: () =>
      import('../tab2/tab2.module').then((m) => m.Tab2PageModule),
  },
  {
    path: 'tab3',
    loadChildren: () =>
      import('../tab3/tab3.module').then((m) => m.Tab3PageModule),
  },
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule],
})
export class LoginPageRoutingModule {}

登录()

this.router.navigate(['/tabs']);

如果你能帮助我，请告诉我。
