Question

我正在使用本地基础的抽屉来为我的反应本机应用程序。当你点击菜单按钮抽屉没有打开，我得到这个错误（_this._drawer.open）不是一个多么好的isse这里是我的代码

import React, { Component } from 'react';
import {
AppRegistry,View
} from 'react-native';
import {ScrollableTab,TabHeading, Drawer, Container,Content, Header, 
Title, Button, Left, Right, Body, Icon ,Text,Tab, Tabs } from 'native-base';
import SecondStatus from './component/StatusComponent';
import HeaderComponent from './component/headerComponent';
import Sports from './component/Sports';
import MainPage from './component/MainPage';
import SideBar from './component/SideBar';

export default class Point extends Component {
    closeDrawer = () => {
    this.drawer.close()
   };
   openDrawer = () => {
    alert('asasa click');
    console.log('asad--');
    this._drawer.open();
    };
   render() {

   return (
          <Container>
           <Drawer
          ref={(ref) => { this._drawer = ref; }}
          content={<SideBar  />}
          onClose={() => this.closeDrawer()} >

            <Header  >
              <Left>
                <Button transparent onPress={this.openDrawer}>
                    <Icon name='arrow-back' />
                </Button>
            </Left>
            <Body>
                <Title>UrduPoint</Title>
            </Body>
            <Right>
                <Button transparent onPress=
         {this.openDrawer.bind(this)}>
                        <Icon name='menu' />
                    </Button>
            </Right>
            </Header>

         </Drawer>




        </Container>
     );
  }
 }

AppRegistry.registerComponent('Point', () => Point);

这是我的SideBar.js

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

export default class SideBar extends Component{
render(){
    return(
 <View>
   <Text>
     asad
     </Text>
   </View>

    )
   };

 }

PS。这个抽屉与npm'alse-native-drawer'

相同

Answer 1

根据native base documentation，您应该致电：

this.drawer.root.open()

Answer 2

我已经使用了反应原生抽屉this npm，这对我有用

Answer 3

以下是其文档中提供的NativeBase Drawer示例示例，其中包含You need to create your own SideBar component and import it.

的说明

抽屉样本代码

import React, { Component } from 'react';
import { Drawer } from 'native-base';
import SideBar from './yourPathToSideBar';
export default class DrawerExample extends Component {
    render() {
      closeDrawer = () => {
        this.drawer._root.close()
      };
      openDrawer = () => {
        this.drawer._root.open()
      };
        return (
            <Drawer
              ref={(ref) => { this.drawer = ref; }}
              content={<SideBar navigator={this.navigator} />}
              onClose={() => this.closeDrawer()} >
            // Main View
          </Drawer>
        );
    }
}

从Sidebar Sample Code

检查NativeBase-KitchenSink

Answer 4

this._drawer._root.open（）

正在为我工作

_this._drawer.open不是函数react-native
