如何在RNRF中使自定义导航栏透明

npm install @react-navigation/native

import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

const Stack = createStackNavigator();

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator
        screenOptions={{
          headerTransparent: true, // 设置导航栏透明
          headerTitle: '', // 隐藏导航栏标题
          headerTintColor: 'white', // 设置导航栏文字颜色
        }}
      >
        {/* 在这里定义你的屏幕 */}
      </Stack.Navigator>
    </NavigationContainer>
  );
}

export default App;

function HomeScreen() {
  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>Home Screen</Text>
    </View>
  );
}

function DetailsScreen() {
  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>Details Screen</Text>
    </View>
  );
}

<Stack.Navigator>
  <Stack.Screen
    name="Home"
    component={HomeScreen}
    options={{
      headerStyle: { backgroundColor: 'transparent' }, // 设置导航栏背景透明
    }}
  />
  <Stack.Screen
    name="Details"
    component={DetailsScreen}
    options={{
      headerStyle: { backgroundColor: 'transparent' }, // 设置导航栏背景透明
    }}
  />
</Stack.Navigator>

npm install react-native-navigation

import { Navigation } from 'react-native-navigation';

Navigation.setDefaultOptions({
  topBar: {
    background: {
      color: 'transparent', // 设置导航栏背景透明
    },
    title: {
      color: 'white', // 设置导航栏标题颜色
    },
  },
});

Navigation.registerComponent('HomeScreen', () => HomeScreen);
Navigation.registerComponent('DetailsScreen', () => DetailsScreen);

Navigation.setRoot({
  root: {
    stack: {
      children: [
        {
          component: {
            name: 'HomeScreen',
            options: {
              topBar: {
                visible: true,
                drawBehind: true, // 设置导航栏透明
              },
            },
          },
        },
      ],
    },
  },
});

import { Navigation } from 'react-native-navigation';

function HomeScreen() {
  useEffect(() => {
    Navigation.mergeOptions(componentId, {
      topBar: {
        background: {
          color: 'transparent', // 设置导航栏背景透明
        },
        title: {
          color: 'white', // 设置导航栏标题颜色
        },
      },
    });
  }, []);

  return (
    <View style={{ flex: 1, justifyContent: 'center', alignItems: 'center' }}>
      <Text>Home Screen</Text>
    </View>
  );
}
