从react中的嵌套导航器导航到父屏幕

import React from 'react';
import { View, Button } from 'react-native';
import { createStackNavigator } from 'react-navigation';

// 子屏幕组件
class ChildScreen extends React.Component {
  render() {
    return (
      <View>
        {/* 子屏幕的内容 */}
      </View>
    );
  }
}

// 父屏幕组件
class ParentScreen extends React.Component {
  static navigationOptions = {
    title: '父屏幕',
  };

  // 导航到子屏幕的函数
  navigateToChildScreen = () => {
    this.props.navigation.navigate('Child');
  };

  render() {
    return (
      <View>
        {/* 父屏幕的内容 */}
        <Button title="导航到子屏幕" onPress={this.navigateToChildScreen} />
      </View>
    );
  }
}

// 创建导航器对象
const AppNavigator = createStackNavigator({
  Parent: { screen: ParentScreen },
  Child: { screen: ChildScreen },
});

export default class App extends React.Component {
  render() {
    return <AppNavigator />;
  }
}
