我有4页：App.js，HomeScreen.js，Login.js，Toolbar.js

使用StackNavigator的“我的应用程序”页面：

import React, { Component } from 'react';
import {
  Platform,
  StyleSheet,
  Text,
  View
} from 'react-native';

import { StackNavigator, DrawerNavigator } from 'react-navigation';

import Splash from './screens/Splash';
import HomeScreen from './screens/HomeScreen';
import Login from './screens/Login';
import Lobby from './screens/Lobby';
import Wifi from './screens/Wifi';
import Toolbar from './components/ToolBar/Toolbar';
import Mobile from './screens/Mobile';


;

const Navigation = StackNavigator({
  Splash:{screen: Splash},
  HomeScreen:{screen: HomeScreen},
  Login:{screen: Login},
  Lobby:{screen: Lobby},
  Wifi:{screen: Wifi},
  Mobile:{screen:Mobile}
}, {
  mode: 'modal',
  headerMode: 'none'
});


export default Navigation;

我要将工具栏导入到HomeScreen，并希望将导航道具从HomeScreen传递到工具栏，以便可以从工具栏和HomeScreen访问登录页面。 …
