抽屉式导航栏在阵营母语

Question

我在反应原生一个新手，不要介意我问一个基本的问题，我想知道，什么是一步一步的过程来实现导航的抽屉里。

简称链接this Link

我不能够整合它。

任何演示项目实施抽屉也可以工作。任何有关此帮助将是巨大的。

谢谢

导航抽屉中实现原生的反应如下：

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={{
                    drawer: {shadowColor: '#000000', shadowOpacity: 0.8, shadowRadius: 3},
                    main: {paddingLeft: 3}
                }}
                tweenHandler={(ratio) => ({
                    main: { opacity:(2-ratio)/2 }
                })}>
                <Navigator
                    ref={(ref) => this._navigator = ref}
                    configureScene={(route) => Navigator.SceneConfigs.FloatFromLeft}
                    initialRoute={{
                        id: 'HomePage',
                        title: 'HomePage',

                    renderScene={(route, navigator) => this._renderScene(route, navigator)}
                    navigationBar={

                    }
                />
            </Drawer>
        );
    }

    _renderScene(route, navigator) {
        switch (route.id) {
            case 'HomePage':
                return ( <HomePage navigator={navigator}/> );

            case 'ProfilePage':
                return ( <ProfilePage navigator={navigator}/> );
        }
    }
}

const NavigationBarRouteMapper = {
    LeftButton(route, navigator, index, navState) {
        switch (route.id) {

首先，你需要安装反应导航包：NPM安装--save反应导航 为了更方便，更舒适，我把代码和注释的每一行我App.js文件

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

Answer 3

从这里下载源代码（Navigation Drawer In React Native）

创建像下面的抽屉式导航菜单：

const MyDrawerNavigator = createDrawerNavigator({
  Home: {
 screen: HomeScreen,
},
Settings: {
screen: SettingScreen,
},
Profile:{
screen: ProfileScreen
}
});


const MyAppdrawer = createAppContainer(MyDrawerNavigator);

谢谢！
