Sono un principiante in react-native, non importa se faccio una domanda di base, volevo sapere, qual è la procedura passo passo per implementare il cassetto di navigazione.Cassetto di navigazione in React-Native

collegamenti di cui this Link

io non sono in grado di integrarlo.

Anche qualsiasi cassetto di implementazione del progetto Demo funzionerà. Qualsiasi aiuto per quanto riguarda questo sarà grande.

Grazie

Attuazione del riquadro di navigazione a reagire nativo come segue:

index.ios.js

'use strict'; 

import React, { AppRegistry } from 'react-native'; 
import App from './components/App'; 

AppRegistry.registerComponent('ReactNativeProject',() => App); 

App.js:

'use strict' 

import React, { Component } from 'react'; 
import { DeviceEventEmitter, Navigator, Text, TouchableOpacity, View } from 'react-native'; 

import Drawer from 'react-native-drawer'; 
import Icon from 'react-native-vector-icons/MaterialIcons'; 
import { EventEmitter } from 'fbemitter'; 

import Menu from './Menu'; 
import HomePage from './HomePage' 
import ProfilePage from './ProfilePage' 

import navigationHelper from '../helpers/navigation'; 

import styles from '../styles/root'; 

let _emitter = new EventEmitter(); 

class App extends Component { 
    componentDidMount() { 
     var self = this; 

     _emitter.addListener('openMenu',() => { 
      self._drawer.open(); 
     }); 

     _emitter.addListener('back',() => { 
      self._navigator.pop(); 
     }); 
    } 

    render() { 
     return (
      <Drawer 
       ref={(ref) => this._drawer = ref} 
       type="overlay" 
       content={<Menu navigate={(route) => { 
        this._navigator.push(navigationHelper(route)); 
        this._drawer.close() 
       }}/>} 
       tapToClose={true} 
       openDrawerOffset={0.2} 
       panCloseMask={0.2} 
       closedDrawerOffset={-3} 
       styles={{

        main: {paddingLeft: 3} 
       }} 
       tweenHandler={(ratio) => ({ 
        main: { opacity:(2-ratio)/2 } 
       })}> 
       <Navigator 
        ref={(ref) => this._navigator = ref}

    _renderScene(route, navigator) {

molto disponibile, ma è necessario mettere stile e –

In primo luogo, è necessario installare il pacchetto reagire-navigazione: NPM installare --save reagire-navigazione
Per rendere più facile e più comodo, ho messo ogni linee di codici e commenti nel mio App.js file di

import React, { Component } from 'react'; 
import { 
    Text, 
    View, 
    StyleSheet 
} from 'react-native'; 
import { DrawerNavigator } from 'react-navigation'; 

// Create HomeScreen class. When 'Home' item is clicked, it will navigate to this page 
class HomeScreen extends Component { 
    render() { 
     return <Text> Home Page </Text> 
    } 
} 

// Create ProfileScreen class. When 'Profile' item is clicked, it will navigate to this page 
class ProfileScreen extends Component { 
    render() { 
    return <Text> Profile Page </Text> 
    } 
} 

// Create SettingsScreen class. When 'Settings' item is clicked, it will navigate to this page 
class SettingsScreen extends Component { 
    render() { 
    return <Text> Settings Page </Text> 
    } 
} 

const RootNavigation = DrawerNavigator({ 
    Home: { screen: HomeScreen }, 
    Profile: { screen: ProfileScreen}, 
    Settings: { screen: SettingsScreen} 
}); 

export default class App extends Component { 
    render() { 
    return <RootNavigation /> 
    } 
} 

Here is my demo
