React Native，自定义 DrawerContent 导航器问题

Question

我有一个自定义 DrawerContent 组件，我无法使用 navigator.navigate('DrawerHelp').

从它导航到屏幕

我仍然收到这个错误，我真的不知道如何解决它。

我正在尝试从“帮助”按钮导航到它自己的名为 DrawerHelp 的组件。

问题带有负载 {"name":"DrawerHelp"} 的操作 'NAVIGATE' 未被任何导航器处理

下面是我的代码。

function DrawerComponent() {
    return (
        <Drawer.Navigator 
            drawerContentOptions={{activeBackgroundColor: '#efefef', activeTintColor: '#000000'}}
            initialRouteName="Tabs" 
            drawerStyle={{ backgroundColor:'#ffffff', width:'85%', paddingBottom: 50 }} 
            drawerContent={ 
                props => ( <CustomDrawerContent {...props} /> )
            }>
            <Drawer.Screen name="Dashboard" component={Tabs} options={{
                drawerIcon: config => <Ionicons name={'ios-home'} size={18} color={'#444'} headerTitle="AAA" />,
            }} />

            <Drawer.Screen name="Help" component={DrawerHelp} 
                options={{
                    drawerIcon: config => <Ionicons name={'ios-people-circle-outline'} size={18} color={'#444'}/>,
                }}
            />
        </Drawer.Navigator>
    );
}

export function CustomDrawerContent (props) {

    const [ tabs, setTabs ] = useState([
        { 
            name: 'Help',
            icon: 'ios-call',
            borderColor: '#e7c53f',
            backgroundColor: '#fff',
            color: '#e7c53f',
            fontWeight: '500'
        },{ 
            name: 'Share',
            icon: 'ios-megaphone',
            borderColor: '#e7c53f',
            backgroundColor: '#fff',

            fontWeight: '500'
        }
    ]);

    return (

Answer 1

它不起作用，因为您定义了名称为 'Help'

的 DrawerComponent

<Drawer.Screen name="Help" component={DrawerHelp} 
  options={{drawerIcon: config => <Ionicons name={'ios-people-circle-outline'} size={18} color={'#444'}/>
                

if(tab.name == 'Help') {
 props.navigation.navigate('DrawerHelp'); <== Change here to Help not DrawerHelp
}
