反应本机createbottomtabnavigator隐藏选项卡栏标签

Question

我需要知道如何隐藏底部标签。

我尝试了以下操作：

  

tabBarShowLabels：“隐藏”，tabbarlabelvisible：否。

我还删除了tabbarlabel: 'Home'，它仍然显示

我们将不胜感激，或者如果有人可以将我指出正确的方向，那么

import {createBottomTabNavigator} from 'react-navigation'
import Icon from 'react-native-vector-icons/Ionicons'


const Tabs = createBottomTabNavigator ({
  Home:{
    screen: Home,
    navigationOptions:{
      tabBarIcon: ({ focused, tintcolor }) => (
        <Icon name="ios-home" size={24}  />
      )
    }
  },
  Inbox:{screen: Inbox,
    navigationOptions:{
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-mail" size={24} />
      )
    }
  },
  Search:{screen: Search,
    navigationOptions:{
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-search" size={24} />
      )
    }
  },
  Favorites:{screen: Favorites,
    navigationOptions:{ 
    tabBarIcon: ({ tintcolor }) => (
      <Icon name="ios-heart" size={24} />
    )
  }
  },
  Settings:{screen: Settings,
    navigationOptions:{ 
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-settings" size={24} />
      )
    }
  }

}
});



export default class App extends Component {
  render() {

    return <Tabs />
  }
}

Answer 1

您必须按照docs的定义来定义showLabel: false，就像

const Tabs = createBottomTabNavigator ({
  Home:{
    screen: Home,
    navigationOptions:{
      tabBarIcon: ({ focused, tintcolor }) => (
        <Icon name="ios-home" size={24}  />
      )
    }
  },
  ...
  ,
  Settings:{screen: Settings,
    navigationOptions:{
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-settings" size={24} />
      )
    }
  }

}
}, {
  tabBarOptions: { showLabel: false }
});

Answer 2

在新版本的React Navigation中，您只需将showLabel属性传递为false

<Tab.Navigator tabBarOptions={{ showLabel: false }}>

Answer 3

以上答案是完美的，但它使括号有些混乱。所以对于像我这样的新蜜蜂，这是正确的代码。

const ProfileStack = createStackNavigator({
  Profile: SettingsScreen
});
ProfileStack.navigationOptions = {
  tabBarIcon: ({ focused }) => (
    <TabBarIcon
      focused={focused}
      title={'Profile'}
      name={focused ? 'tabIcon' : 'tabIconFocused'}
    />
  ),
  tabBarOptions: { showLabel: false }
};

Answer 4

对于react-navigation v4，请将labeld属性设置为false，以仅显示图标。

    const Tabs = createBottomTabNavigator ({
  Home:{
    screen: Home,
    navigationOptions:{
      tabBarIcon: ({ focused, tintcolor }) => (
        <Icon name="ios-home" size={24}  />
      )
    }
  },
  ...
  ,
  Settings:{screen: Settings,
    navigationOptions:{
      tabBarIcon: ({ tintcolor }) => (
        <Icon name="ios-settings" size={24} />
      )
    }
  }

}
}, {labeled:false});
