我正在使用反应导航 . 我想在屏幕的 Headers 上显示抽屉 . 当我打开抽屉时，我的 Headers 目前没有隐藏在抽屉下面 .

import React from 'react';
import { View, Text, StyleSheet } from 'react-native';
import { createStackNavigator, createDrawerNavigator  } from 'react-navigation';
import CategoryScreen from './CategoryScreen';
import ProductsScreen from './ProductsScreen';
import CartScreen from './CartScreen';


const drawerScreens = createDrawerNavigator ({
    Category: CategoryScreen,
    Products: ProductsScreen,
},{
    initialRouteName: 'Category'
}
)


export default AppStack = createStackNavigator(
    { 
        drawer: {
            screen: drawerScreens,
            navigationOptions: ({ navigation }) => ({
                header: <View style={styles.container}><Text>Header</Text></View>
              }),
        }, 
        cart: {screen: CartScreen} 
    },
    {
        initialRouteName: 'drawer',
    }
);

const styles = StyleSheet.create({
    container: {
        height: 100,
        justifyContent: 'center',
        alignItems: 'center',
        backgroundColor: 'orange',
    }
})

那么如何显示抽屉导航抽屉重叠或覆盖的 Headers .

目前看起来像这样

    • 您应该为 CategoryScreen 和 ProductScreen 创建一个新的StackNavigator

    • 您在 CategoryScreen 和 ProductScreen 导航选项上设置 Headers

    这就是我的意思

    // wrap your screen inside the drawer into StackNavigator
const CategoryNavigator = createStackNavigator({
  CategoryList: {
    screen: CategoryScreen,
    navigationOptions: {
      title: "Category",
      header: // any custom header here
    }
  },
});

const drawerScreens = createDrawerNavigator({
  Category: CategoryNavigator,
  Products: ProductNavigator,
}, {
  initialRouteName: 'Category'
})


export default AppStack = createStackNavigator({
  drawer: {
    screen: drawerScreens,
  },
  cart: {
    screen: CartScreen
  }
}, {
  initialRouteName: 'drawer',
});

    结果就是这样

    Embedded StackNavigator

    Following will make a floating header which similar with your screenshot

    将 Headers 模式设置为 float （您不需要将 CategoryScreen 和 ProductScreen 包装成 StackNavigator ）

    export default AppStack = createStackNavigator({
  drawer: {
    screen: drawerScreens,
  },
  cart: {
    screen: CartScreen
  }
}, {
  headerMode: 'float', // set this header mode to float so you can share the header
  initialRouteName: 'drawer',
});

    如果您将 Headers 模式更改为float
    Float header
    ，则会出现此结果

    在我的情况下，我制作自己的Header组件并在我想要的每个页面中使用它 . 它使我能够为每个页面自定义 Headers .

    绝对是后门的方式，我希望其他人有你的问题的确切答案 .

    这是一个例子......

    主页：

    export default class Home extends Component {
    render() {  
        return (
            <View style={{ flex: 1 }}>

                <Header showBorder={true}/>

                <ScrollView>
                   ...
                </ScrollView>
            </View>
        );
    }
}

    Headers 组件：

    export default class Header extends React.PureComponent {

  renderTitle = () => {
    if (this.props.title) {
      return (
        <View style={{ flexDirection: 'column', flex: 3, justifyContent: 'center' }}>
          <View style={{ alignSelf: 'flex-start' }}>
            <Text style={[styles.fontBold, { fontSize:17, color: colors.borderWidthColor }]}>{this.props.title}</Text>
          </View>
        </View>
      )
    }
  }

  renderBack = () => {
    if (this.props.back) {
      return (
        <View style={{ marginTop:3 }}>
          <TouchableOpacity
            onPress={() => {
              this.props.navigation.goBack()
            }}
            style={{ alignSelf: 'flex-start' }}>
            <Icon name="md-arrow-back" size={23} color="black" />
          </TouchableOpacity>
        </View>
      )
    }
  }


  render() {
    return (
      <View style={[{ height: 70, backgroundColor: this.props.backgroundColor, width: win.width, borderBottomWidth: this.props.showBorder ? 1 : 0 }]}>
        <View style={{ flex: 1, flexDirection: 'row', marginTop: Platform.OS == 'ios' ? 17 : 3 }}>
          <View style={{ flexDirection: 'column', flex: 1, justifyContent: 'center', marginLeft: 12 }}>
            {this.renderBack()}
            {this.renderTitle()}
          </View>
        </View>
      </View>
    )
  }
}
