我想从选项卡上的特定按钮打开抽屉(例如,选项菜单),而不是导航至屏幕。我当前的解决方案正在使用react-navigation v2,但是随着我们从v2升级到react-navigation的v3,并从v57升级到react-native的v60,该解决方案已停止工作。
在标签栏中有一个分配给菜单标签按钮的虚拟屏幕,我正在使用tabBarOnPress()
拦截导航操作。该方法将打开抽屉,如果与菜单按钮的路径名称匹配,则返回该方法,否则它将导航。不论我分配给tabBarOnPress()
的哪种方法,该选项卡导航器似乎都在导航至虚拟屏幕,并且该方法也被调用。
以下是当前代码,该代码在v2上运行良好,但是在v3中已停止运行:
class SlideMenuScreen extends Component {
render() {
return null;
}
}
const tab = createBottomTabNavigator({
Products: {
screen: AppStack,
navigationOptions: {
tabBarLabel: 'Home',
tabBarIcon: ({ tintColor }) => (
<SimpleLineIcons name='home' size={20} color={tintColor} />
)
}
},
Cart: {
screen: CartScreen,
navigationOptions: {
tabBarLabel: 'Cart',
tabBarIcon: ({ tintColor }) => (
<EvilIcons
reverse
name='cart'
type='font-awesome'
color={tintColor}
size={30}
/>
)
}
},
SignIn: {
screen: AuthStack,
navigationOptions: {
tabBarLabel: 'Sign in',
tabBarIcon: ({ tintColor }) => (
<SimpleLineIcons
name='login'
color={tintColor}
size={20}
/>
)
}
},
SideMenu: {
screen: SlideMenuScreen,
navigationOptions: (props) => ({
tabBarLabel: 'Menu',
tabBarIcon:
<Entypo
name='menu'
color={props.tintColor}
size={20}
/>
})
}
},
{
initialRouteName: 'Products',
swipeEnabled: true,
tabBarOptions: {
showLabel: false,
showIcon: true,
activeTintColor: config.themeBackgroundColor,
inactiveTintColor: 'grey',
},
}
);
tab.navigationOptions = ({ navigation }) => {
const { routeName } = navigation.state.routes[navigation.state.index];
if (routeName === 'SideMenu') {
navigation.openDrawer();
return;
}
navigation.navigate(routeName);
};
const sideMenu = createDrawerNavigator({
Home: tab
}, {
initialRouteName: 'Home',
drawerPosition: 'right',
drawerOpenRoute: 'DrawerOpen',
drawerCloseRoute: 'DrawerClose',
drawerToggleRoute: 'DrawerToggle',
drawerWidth: 250,
contentComponent: signedOutDrawerContent
}
);

您可以通过在tabBarOnPress
上使用navigationOptions
来将默认选项卡图标按处理程序更改为所需的任何内容:
Search: {
screen: SearchStack,
navigationOptions: {
tabBarIcon: ({ tintColor }) => <Icon name='search' color={tintColor} size={25} />,
tabBarOnPress: () => alert('hello')
}
},
