TabNavigator 也是react-navigation包下的,用法也相当简单

const ITNewsTabNavigator = TabNavigator({
  Main: {
    screen: HomeComponent,
    navigationOptions: {
      title: 'IT资讯',
      headerTitle: 'IT资讯',
      tabBarLabel: "IT资讯",
      tabBarIcon: ({tintColor}) => (
        <Icon
          name="home"
          size={24}
          color={tintColor}
        />
      )
    }
  },
  User: {
    screen: UserComponent,
    navigationOptions: {
      title: '我的',
      headerTitle: '我的',
      tabBarLabel: "我的",
      tabBarIcon: ({tintColor}) => (
        <Icon
          name="user"
          size={24}
          color={tintColor}
        />
      )
    }
  }
}, {
  tabBarComponent: TabBarBottom,
  tabBarPosition: 'bottom',
  swipeEnabled: false,
  animationEnabled: false,
  backBehavior: 'none',
})

这样就可以得到一个底部有两栏的一个布局,效果图可见 https://github.com/tomoya92/ITNews-React-Native

说明:

  • tabBarComponent: TabBarBottom, tabBarPosition: 'bottom', 这两个配置是将Android上显示在上面tabbar弄下来显示的
  • swipeEnabled: false, 允许左右滑动切换视图,iOS上可以,Android不行
  • animationEnabled: false, 滑动的时候动画,iOS上可以,Android不行
