> RN 项目 安装 react-navigation 路由导航库 react-native-vector-icons 图标库

# 安装 react-navigation 
    yarn add react-navigation react-native-gesture-handler react-native-vector-icons

// package.json
    { 
      "name": "RNApp",
      "version": "0.0.1",
      "private": true,
      "scripts": { 
        "start": "react-native start",

        "lint": "eslint .",
        "postinstall": "npx jetify"
      },

      },
      "jest": { 
        "preset": "react-native"
      }
    }

> android环境运行，需安装 **jetifier**，在package.json中配置 “postinstall”: “npx jetify”，执行 yarn

# 安装 jetifier
    yarn add jetifier --dev

> 具体使用方法如下：  
> createStackNavigator：用于定义路由，实现页面跳转  
> createBottomTabNavigator：用于定义底部导航栏，实现页面切换  
> createAppContainer：用于管理路由、导航容器  
> Icon：用于定义字体图标  
> this.props.navigation.navigate(“NewsDetail”, \{ content: “I come from News” \})：用于父子路由跳转，传参  
> this.props.navigaiton.state.params：用于接收父级路由传参  
> 同时还可以动态设置子路由组件的标题
