我是使用React Native的新手,我在使用React Navigation显示/显示标题标题时遇到问题,我尝试查找但全部失败。
这是我完整的脚本:
Loginscreen.js
class LoginScreen extends Component {
static navigationOptions = {
title: 'Login',
};
render() {
return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
<Text>Login Screen</Text>
<Button title="Login To" onPress={() => this.props.navigation.navigate('Tabs')} />
<Button title="Go To Register" onPress={() => this.props.navigation.navigate('Register')} />
</View>
);
}
}
RegisterScreen.js
class RegisterScreen extends Component {
static navigationOptions = {
title: 'Register',
};
render() {
return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
<Text>Register Screen</Text>
<Button title="Go to Login" onPress={() => this.props.navigation.navigate('Login')} />
</View>
);
}
}
HomeScreen.js
class HomeScreen extends Component {
static navigationOptions = {
title: 'Home',
};
render() {
return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
<Text>Home Screen</Text>
<Button title="Go to Login" onPress={() => this.props.navigation.navigate('Login')} />
</View>
);
}
}
ProfileScreen.js
class ProfileScreen extends Component {
static navigationOptions = {
title: 'Profile',
};
render() {
return (
<View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
<Text>Profile Screen</Text>
<Button title="Go to Login" onPress={() => this.props.navigation.navigate('Login')} />
</View>
);
}
}
请任何人帮助我显示/显示标题标题(红色圆圈),组件LoginScreen和Register中的标题很好,但是丢失了HomeScreen和ProfileScreen组件。请帮助我显示/显示它。
谢谢。

在堆栈导航器中定义headerMode: 'screen',
。
即您的rootStack
const rootStack = createStackNavigator(
{
},{
headerMode: 'screen'
})

如果没有,则必须重新加载应用程序,因为navigationOptions是静态的,因此它们仅在应用程序启动时加载一次,并且不会更新。
