React Native 中 react-navigation 导航器的使用 [亲测可用] webflexrnreactnative

 

在 React Native 中，官方已经推荐使用 react-navigation 来实现各个界面的跳转和不同板块的切换。 react-navigation 主要包括三个组件：

• TabNavigator 切换组件 ，用来实现同一个页面上不同界面的切换，即tab选项卡
• StackNavigator 导航组件，用于实现各个页面之间的跳转，即页面跳转（通过stack栈记录）
• DrawerNavigator 抽屉组件，可以实现侧滑的抽屉效果 

我这主要用 StackNavigator 先.因为用的是组件之间的跳转

先创建路由文件: 导入相关.导入组件,定义好地址

navigator/AppNavigator.js

​

//导航器
import React, {Component} from 'react';
import {Platform,Button,ScrollView,SafeAreaView,View} from 'react-native';
import {createStackNavigator,createMaterialTopTabNavigator,createBottomTabNavigator,createDrawerNavigator,DrawerItems,createSwitchNavigator} from 'react-navigation'
import Ionicons from 'react-native-vector-icons/Ionicons'
import MaterialIcons from 'react-native-vector-icons/MaterialIcons'


//引入组件页面
import HomePage from '../pages/HomePage'
import Page1 from '../pages/Page1'
import Page2 from '../pages/Page2'
import Page3 from '../pages/Page3'
import Page4 from '../pages/Page4'
import Page5 from '../pages/Page5'
import Login from '../pages/Login'


//1 创建两个导航器,用于演示createSwitchNavigator
const AppStack = createStackNavigator({
    Home: {
        screen:HomePage
    },
    Page1: {
        screen:Page1
    },
    Page2: {
        screen:Page2
    }
})
const AuthStack = createStackNavigator({ //默认启动打开的组件 相当于 web 的  index.html
    Login: {
        screen:HomePage
    }
})
//2 将用于演示 1 createSwitchNavigator导航器导出
export const AppSwitchNavigator =  createSwitchNavigator({
    Auth:AuthStack,
    App:AppStack
}, {
    initialRouteName:'Auth'
})

然后创建对应的组件文件:

​

再在App.js 中:

import React, {Component} from 'react';
import {Platform, StyleSheet, Text, View,Image} from 'react-native';



export default class App extends Component<Props> {

  constructor(props) {
    super(props);
    this.state = {
      selectedTab:'home'
    }
  }

  render() {
    return (
        <View style={styles.container}>
          <Text>{'首页'}</Text>
        </View>
    );
  }
}

const styles = StyleSheet.create({
  container: {
    flex: 1
  }
});

最后再index.js里面:

/**
 * @format
 */

import {AppRegistry} from 'react-native';
import {name as appName} from './app.json';

import App from './App';
import {createAppContainer} from 'react-navigation'

//导入导航器(SwitchNavigator)
import {AppSwitchNavigator} from './navigator/AppNavigator'


//在新版的react-navigation里面提供了 一个createAppContainer组件
const AppSwitchNavigatorContainer = createAppContainer(AppSwitchNavigator)

AppRegistry.registerComponent(appName, () => AppSwitchNavigatorContainer);
