javascript - 改变反应原生tabBar的背景颜色

Question

所以我真的是反应原生和移动开发的新手，我想改变底部标签栏导航的背景颜色，我似乎不知道该怎么做，因为我从一个带导航的反应原生项目开始（世博会初始化阶段的选项），内容的编写方式与我在网上看到的不同，我知道我需要添加

      tabBarOptions: {
        style: { backgroundColor: 'orange'}
      }

但老实说，我知道确切的位置，如果有人可以提供帮助，将不胜感激！这是我的代码：

import React from 'react';
import { Platform } from 'react-native';
import { createStackNavigator } from 'react-navigation-stack';
import { createBottomTabNavigator } from 'react-navigation-tabs';

import TabBarIcon from '../components/TabBarIcon';
import HomeScreen from '../screens/HomeScreen';
import LinksScreen from '../screens/LinksScreen';
import SettingsScreen from '../screens/SettingsScreen';


const config = Platform.select({
  web: { headerMode: 'screen' },
  default: {},
});

const HomeStack = createStackNavigator(
  {
    Home: HomeScreen,
  },{
    defaultNavigationOptions: {
      headerTintColor: '#444',
      headerStyle: {
        backgroundColor: 'pink'
      }
    }
  },
  config
);

HomeStack.navigationOptions = {
  tabBarLabel: 'Home',
  tabBarIcon: ({ focused, tintColor }) => (
    <TabBarIcon
      focused={focused}
      name={
        Platform.OS === 'ios'
          ? `ios-information-circle${focused ? '' : '-outline'}`
          : 'md-information-circle'
      }
      color= {"#cd077dr"}
    />
  ), style: {
    backgroundColor: 'pink'
  }
};

HomeStack.path = '';

const LinksStack = createStackNavigator(
  {
    Links: LinksScreen,
  },{
    defaultNavigationOptions: {
      headerTintColor: '#444',
      headerStyle: {
        backgroundColor: 'pink'
      }
    }
  },
  config
);

LinksStack.navigationOptions = {
  tabBarLabel: 'Links',
  tabBarIcon: ({ focused }) => (
    <TabBarIcon focused={focused} name={Platform.OS === 'ios' ? 'ios-link' : 'md-link'} />
  )
};

LinksStack.path = '';

const SettingsStack = createStackNavigator(
  {
    Settings: SettingsScreen,
  },{
    defaultNavigationOptions: {
      headerTintColor: '#444',
      headerStyle: {
        backgroundColor: 'pink'
      },
      tabBarOptions: {
        style: { backgroundColor: 'orange'}
      }
    }
  },
  config
);

SettingsStack.navigationOptions = {
  tabBarLabel: 'Settings',
  tabBarIcon: ({ focused }) => (
    <TabBarIcon focused={focused} name={Platform.OS === 'ios' ? 'ios-options' : 'md-options'} />
  ),
};

SettingsStack.path = '';


const tabNavigator = createBottomTabNavigator({
  HomeStack,
  LinksStack,
  SettingsStack,
});

tabNavigator.path = '';

export default tabNavigator;

我认为您应该将 const tabNavigator 编辑为类似

const tabNavigator = createBottomTabNavigator({
  HomeStack,
  LinksStack,
  SettingsStack,
}, {
    defaultNavigationOptions: {
      tabBarOptions: {
        style: { backgroundColor: 'orange'}
      }
    }
});
