React Navigation Header 总是显示

Question

I am trying to create multiple screens and to switch between them I thought react-navigation would be great. But I am getting this problem of header appearing automatically, despite setting header to null. I have my App.js createStackNavigation as:

const AppNavigator = createStackNavigator({


register : {
  screen: RegisterScreen, 
},

login: {
  screen: LoginScreen,
},

home : {
  screen: HomeScreen
},

  },

  {
    navigationOptions: {
      header:null,
      headerMode: 'none',
    }
  }
  );

Here I have three screens. Namely register, login and home. Inside register screen I have other createStackNavigator for registerFinal, login and register screen itself. It is shown below.

const registerNavigation = createStackNavigator(
    {
        register: {
            screen: RegisterScreen,
            headerMode: 'none',
            navigationOptions: ({ navigation }) => ({
                header: null,
              }),
        }, 
        registerFinal: {
            screen: RegisterFinalScreen, 
            navigationOptions: ({ navigation }) => ({
                header: null,
                headerShown: false

              }),
        } ,
        login: {
            screen: LoginScreen, 
            navigationOptions: ({ navigation }) => ({
                header: null,
                headerShown: false
              }),
        },
    },

    {
        navigationOptions: ({ navigation }) => ({
            header: null,
            headerShown: false
          }),
    }
    );

Though, I have header disabled in navigationOptions using both methods as specified in other questions, none of them seems to work for me. I am getting two header in my screen. How do I solve this?

Answer 1

Restarting the emulator solved the problem. OMG. This thing had me change my project so many times. But sometimes, you just have to laugh at it.

Answer 2

Another way of hiding Headers are:

export default class LoginPage extends Component{
  static navigationOptions = { // remove header on this page
      header: null
  }
}

Answer 3

Use headerMode not headerShown on the registeration stack as well.

Basically change your registeration stack to reflect the following:

const registerNavigation = createStackNavigator(
    {
        register: {
            screen: RegisterScreen,
            headerMode: 'none',
            navigationOptions: ({ navigation }) => ({
                header: null,
            }),
        },
        registerFinal: {
            screen: RegisterFinalScreen,
            navigationOptions: ({ navigation }) => ({
                header: null,
                headerMode: 'none'

            }),
        },
        login: {
            screen: LoginScreen,
            navigationOptions: ({ navigation }) => ({
                header: null,
                headerMode: 'none'
            }),
        },
    },

    {
        navigationOptions: ({ navigation }) => ({
            header: null,
            headerMode: 'none'
        }),
    }
);const registerNavigation = createStackNavigator(
    {
        register: {
            screen: RegisterScreen,
            headerMode: 'none',
            navigationOptions: ({ navigation }) => ({
                header: null,
            }),
        },
        registerFinal: {
            screen: RegisterFinalScreen,
            navigationOptions: ({ navigation }) => ({
                header: null,
                headerMode: 'none'

            }),
        },
        login: {
            screen: LoginScreen,
            navigationOptions: ({ navigation }) => ({
                header: null,
                headerMode: 'none'
            }),
        },
    },

    {
        navigationOptions: ({ navigation }) => ({
            header: null,
            headerMode: 'none'
        }),
    }
);

Hope this Helps!

Answer 4

headerMode: 'none' should not be inside navigationOptions :

const AppNavigator = createStackNavigator({
 // ...
}, {
  // No `navigationOptions` here
  headerMode: 'none'
})

Answer 5

Most of the times you will need to restart EXPO or RN cli in order for Simulator to take the change.

This is how you hide the header on one screen

`yourComponentName`.navigationOptions = () => {
    return {
        headerShown: false
    }
}

//above code needs to be before you EXPORT your component

export default `yourComponentName`

You could also hide header on all screens, check like this.

Tip: instead of adding headerShown: false to each screen's option, you can add screenOptions={{ headerShown: false }} to the navigator to set the option for all of the screens.

Answer 6

Create one object as below

const screenOptions = {
    headerShown: false,
};

And then use options like I used below

    <NavigationContainer>
        <Stack.Navigator initialRouteName="Home"  >
            <Stack.Screen name="Home" component={Home} options={screenOptions} />
        </Stack.Navigator>
    </NavigationContainer>

Following this will not show component name when called.

Final version will look like this

import React from 'react';
import { createStackNavigator } from '@react-navigation/stack';
import { NavigationContainer } from '@react-navigation/native';
import Home from './screens/Home';

export default function RootNavigation() {
const Stack = createStackNavigator();

const screenOptions = {
    headerShown: false,
};

return (
    <NavigationContainer>
        <Stack.Navigator initialRouteName="Home"  >
            <Stack.Screen name="Home" component={Home} options={screenOptions} />
        </Stack.Navigator>
    </NavigationContainer>
);
}
