抽屉导航

导航中的常见模式是使用左侧（有时是右侧）的抽屉在屏幕之间导航。

¥Common pattern in navigation is to use drawer from left (sometimes right) side for navigating between screens.

在继续之前，首先安装并配置 @react-navigation/drawer 及其依赖，然后安装 安装说明。

¥Before continuing, first install and configure @react-navigation/drawer and its dependencies following the installation instructions.

要使用此抽屉式导航器，请从 @react-navigation/drawer 导入它：（向右滑动打开）

¥To use this drawer navigator, import it from @react-navigation/drawer: (swipe right to open)

import * as React from 'react';
import { Button, View } from 'react-native';
import { createDrawerNavigator } from '@react-navigation/drawer';
import { NavigationContainer } from '@react-navigation/native';

function HomeScreen({ navigation }) {
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Button
        onPress={() => navigation.navigate('Notifications')}
        title="Go to notifications"
      />
    </View>
  );
}

function NotificationsScreen({ navigation }) {
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Button onPress={() => navigation.goBack()} title="Go back home" />
    </View>
  );
}

const Drawer = createDrawerNavigator();

export default function App() {
  return (
    <NavigationContainer>
      <Drawer.Navigator initialRouteName="Home">
        <Drawer.Screen name="Home" component={HomeScreen} />
        <Drawer.Screen name="Notifications" component={NotificationsScreen} />
      </Drawer.Navigator>
    </NavigationContainer>
  );
}

打开和关闭抽屉

¥Opening and closing drawer

要打开和关闭抽屉，请使用以下助手：

¥To open and close drawer, use the following helpers:

navigation.openDrawer();
navigation.closeDrawer();

如果你想切换抽屉，请调用以下命令：

¥If you would like to toggle the drawer you call the following:

navigation.toggleDrawer();

这些函数中的每一个都在幕后简单地调度操作：

¥Each of these functions, behind the scenes, are simply dispatching actions:

navigation.dispatch(DrawerActions.openDrawer());
navigation.dispatch(DrawerActions.closeDrawer());
navigation.dispatch(DrawerActions.toggleDrawer());

如果你想确定抽屉是打开还是关闭，你可以执行以下操作：

¥If you would like to determine if drawer is open or closed, you can do the following:

import { useDrawerStatus } from '@react-navigation/drawer';

// ...

const isDrawerOpen = useDrawerStatus() === 'open';
