React Navigation 5 隐藏抽屉项目

Question

我试图隐藏在抽屉导航器中按下我的一条路线的能力，因为它是另一个导航器和应用程序中的默认位置。我希望抽屉仅用于导航到不适合其他地方的用户流的无关路线。在 React Navigation 5 之前，我可以通过简单地设置 drawerLabel: () => null 来实现这一点。但是现在有了这些更改，我无法弄清楚如何以相同的方式隐藏它。

以下是我当前的导航器代码：

const DrawerNavigator = () => {
    const dispatch = useDispatch();
    return (
    <MainDrawerNavigator.Navigator 
        drawerContent={props => customDrawerContent(props, dispatch)}
        drawerStyle={drawerStyle}
    >
        <MainDrawerNavigator.Screen 
            name="DrawerNav"
            component={MainTabNavigator}
            options={{
                drawerLabel: () => null,
                title: null,
                drawerIcon: () => null
            }}
        />

        <MainDrawerNavigator.Screen
            name="FAQNav"
            component={FAQStackNavigator}
            options={
                { 
                    drawerLabel: "FAQ", 
                    drawerIcon: ({tintColor}) => <EvilIcons name={'question'} size={30} color={tintColor} />
                }
            }
        />
    </MainDrawerNavigator.Navigator>
    )
}

const customDrawerContent = (props, dispatch) => {
    console.log(props.descriptors)
    return (
        <View style={{flex: 1}}>
            <View style={{height: '90%'}}>

                <DrawerContentScrollView {...props}>
                        <View style={styles.logoContainer}>
                            <Image 
                                style={styles.image} 
                                fadeDuration={0} 
                                resizeMode={'contain'} 
                                source={require('../assets/images/spikeball-logo-horizontal.png')} 
                            />
                        </View>

                        <TouchableOpacity style={styles.contactUsContainer} onPress={() => { Linking.openURL('https://spikeball.com/')}}>
                            <AntDesign style={styles.iconStyle} name={'shoppingcart'} size={25} color={'black'} />

                            <Text style={styles.drawerText}>Shop</Text>                    
                        </TouchableOpacity>

                        <TouchableOpacity style={styles.contactUsContainer} onPress={() => { Linking.openURL('https://support.spikeball.com/')}}>
                            <AntDesign style={styles.iconStyle} name={'contacts'} size={25} color={'black'} />

                            <Text style={styles.drawerText}>Contact Us</Text>                    
                        </TouchableOpacity>

                        <DrawerItemList 
                            {...props}
                        />

                </DrawerContentScrollView>
            </View>

            <TouchableOpacity 
                style={styles.logoutContainer} 
                onPress={() => { 
                    dispatch(authActions.logout());
                }}>
                    <Text style={styles.logoutText}>SIGN OUT</Text>                    
            </TouchableOpacity>
        </View>
    )
}

Answer 1

最好的解决方案是在将 props 传递给 DrawerItemList 之前对其进行过滤。这只适用于反应导航 5

//custom drawer content
export default props => {
const { state, ...rest } = props;
const newState = { ...state}  //copy from state before applying any filter. do not change original state
newState.routes = newState.routes.filter(item => item.name !== 'Login') //replace "Login' with your route name

return (
     <DrawerContentScrollView {...props}>
         <DrawerItemList state={newState} {...rest} />
    </DrawerContentScrollView>
)

}

Answer 3

浏览了 React Navigation 源代码后，我认为最好的选择是在要隐藏的抽屉屏幕上添加一个drawerItemStyle 选项。只需将高度设置为 0。

例如

<Drawer.Screen
  name="Home"
  component={MainStackScreen}
  options={{
    drawerItemStyle: { height: 0 }
  }}
/>

它似乎工作得很好。

我正在使用 React Navigation 6，但这可能也适用于 v5。

Answer 4

对我来说，您最好创建一个嵌套导航器，其中包含 https://reactnavigation.org/docs/nesting-navigators/#navigator-specific-methods-are-available-in-the-navigators-nested-inside 中记录的堆栈和抽屉屏幕，而不是隐藏抽屉项目。

React Navigation 5 的解决方案

我最终使用了以下代码 -

drawerContent={props => customDrawerContent(props, dispatch)}

customDrawerContent 的代码 -

{state.routes.map((route, i) => {
          if(route.name === 'App') return;
          const focused = i === state.index;
          const { title, drawerLabel, drawerIcon } = descriptors[route.key].options;

          return (
            <DrawerItem
              key={route.key}
              label={
                drawerLabel !== undefined
                  ? drawerLabel
                  : title !== undefined
                  ? title
                  : route.name
              }
              icon={drawerIcon}
              focused={focused}
              activeTintColor={activeTintColor}
              inactiveTintColor={inactiveTintColor}
              activeBackgroundColor={activeBackgroundColor}
              inactiveBackgroundColor={inactiveBackgroundColor}
              labelStyle={labelStyle}
              style={itemStyle}
              to={buildLink(route.name, route.params)}
              onPress={() => {
                navigation.dispatch({
                  ...(focused
                    ? DrawerActions.closeDrawer()
                    : CommonActions.navigate(route.name)),
                  target: state.key,
                });
              }}
            />
          );
        })}

Answer 6

在我踩到 Github 上的 How to hide DrawerView.Item in DrawerNavigator contentComponent #795 之前，上述解决方案均不适合我。

其他人 cmets 允许我为 react-native v5 提出一个动态且可行的解决方案。

const CustomDrawer = props => {
  const {state, descriptors, navigation} = props;
  const buildLink = useLinkBuilder();

  return (
    <DrawerContentScrollView {...props}>
      {state.routes.map((route, i) => {
        const isHidden = descriptors[route.key].options?.hidden; // <--- Added this line
        if (isHidden === true) return null; // <--- Added this line

        const focused = i === state.index;
        const {
          title,
          drawerLabel,
          drawerIcon,
          drawerActiveTintColor,
          drawerInactiveTintColor,
          drawerActiveBackgroundColor,
          drawerInactiveBackgroundColor,
          drawerLabelStyle,
          drawerItemStyle,
        } = descriptors[route.key].options;

        return (
          <DrawerItem
            key={route.key}
            label={
              drawerLabel !== undefined
                ? drawerLabel
                : title !== undefined
                ? title
                : route.name
            }
            icon={drawerIcon}
            focused={focused}
            activeTintColor={drawerActiveTintColor}
            inactiveTintColor={drawerInactiveTintColor}
            activeBackgroundColor={drawerActiveBackgroundColor}
            inactiveBackgroundColor={drawerInactiveBackgroundColor}
            labelStyle={drawerLabelStyle}
            style={drawerItemStyle}
            to={buildLink(route.name, route.params)}
            onPress={() => {
              navigation.dispatch({
                ...(focused
                  ? DrawerActions.closeDrawer()
                  : CommonActions.navigate(route.name)),
                target: state.key,
              });
            }}
          />
        );
      })}
    </DrawerContentScrollView>
  );
};

export default CustomDrawer;

那么你所要做的就是在 Drawer.Navigator 中使用 CustomDrawer 并将隐藏选项传递给 Drawer.Screen，如下所示：

<Drawer.Navigator
              initialRouteName={ROUTES.SIGN_IN}
              drawerPosition="right"
              drawerContent={props => <CustomDrawer {...props} />}>
              <Drawer.Screen
                name={ROUTES.SIGN_IN}
                component={SignInContainer}
                options={{headerShown: false, hidden: true}}
              />
              <Drawer.Screen
                name={ROUTES.DASHBOARD}
                component={withHeader(DashboardContainer)}
                options={{headerLeft: false}}
              />
</Drawer.Navigator>

Answer 7

@Lenin Sheikh 解决方案有效，但正如 cmets 中强调的那样，它引入了另一个问题，即无法单击抽屉菜单中的某些组件。我通过两个步骤解决了这个问题（显然是在应用@Lenin Sheikh 解决方案之后）。

1. 将隐藏的项目移到列表底部

2. 选择一个默认组件，尤其是当它是隐藏组件之一时

   <Drawer.Navigator
             initialRouteName='Home'// Specify the default component
          drawerContent={
            (props) => (
              <DrawerList {...props} />)
          }>
   
          <Drawer.Screen name="Component 1"
                         component={Component1}
                         options={{ title: "Component one", headerShown: 
      false }} />
   
    <Drawer.Screen name="Component 2"
                     component={Component2}
                     options={{ title: "Component 2", headerShown: false 
   }} />
   
   
   
    <Drawer.Screen name="Logout"
                 component={LogoutPage}
                 options={{ title: "Logout", headerShown: true }} />
   
   <Drawer.Screen name="Home" component={HomePage}
                 options={{
                   title: "",
                   headerShown: false,
   
                 }} />//This is the hidden component
   
   </Drawer.Navigator>
   

Answer 8

我刚刚找到了解决类似问题的方法。长话短说，我使用 Stack、Tabs 和 Drawer（用于汉堡菜单）。我设法合并了所有导航，但抽屉显示了我不想要的主页按钮。

我找到的解决方案在这里：

• https://aboutreact.com/how-to-hide-navigation-drawer-sidebar-option/

• https://snack.expo.io/embedded/@aboutreact/keeping-the-screen-in-navigation-drawer-but-hide-its-name-from-navigation-options?iframeId=thkothhhej&preview=true&platform=ios&theme=dark

我也遇到了问题，第一个抽屉菜单选项被突出显示并且不可点击。为此，我只需将隐藏的菜单屏幕移动到抽屉导航的底部。 :) 我知道这不是最漂亮的解决方案，但我想我明白了。我希望它会帮助某人。这是我的代码：

function DrawerNavigator() {
  return (
    <NavigationContainer>
      <Drawer.Navigator
        initialRouteName="Home"
        drawerContent={props => {
          const filteredProps = {
            ...props,
            state: {
              ...props.state,
              routeNames: props.state.routeNames.filter(routeName => {
                routeName !== 'Home';
              }),
              routes: props.state.routes.filter(route => route.name !== 'Home'),
            },
          };
          return (
            <DrawerContentScrollView {...filteredProps}>
              <DrawerItemList {...filteredProps} />
            </DrawerContentScrollView>
          );
        }}>
        <Drawer.Screen name="Notifications" component={ProfileScreen} />
        <Drawer.Screen name="Notifications2" component={ProfileScreen} />
        <Drawer.Screen name="Home" component={StackNavigator} />
      </Drawer.Navigator>
    </NavigationContainer>
  );
