import React , {Component} from 'react';
import {
  AppRegistry,  
  View,
  StyleSheet,
  Text,
  Button
} from 'react-native';
import {StackNavigator} from 'react-navigation' 

export class ChatScreen extends Component {
   static navigationOptions = {
    title: 'chat with lucy',
  };
  render() {
    return (
      <View>
        <Text>Chat with Lucy</Text>
      </View>
    );
  }
}

export default class HomeScreen extends Component{
  static navigationOptions = {
    title: 'Welcome',
  };
  render(){
    const {navigate} = this.props.navigation;
    return( 
      <View> 
        <Text>Hello, Chat App!</Text>
        <Button 
          onPress={() => navigate('Chat')}
          title='Chat with Lucy'
        />
      </View> 
    )
  }
}
const SimpleApp = StackNavigator({
  Home: {screen: HomeScreen},
  Chat: {screen: ChatScreen},
}); 

AppRegistry.registerComponent('thirtyDayOfReactNative', () => SimpleApp);

• 页面直接传递参数

export class ChatScreen extends Component { 
  static navigationOptions = ({ navigation }) => ({  
    title: 'Chat with ' + navigation.state.params.user,
  });
  render() {
    const {params} = this.props.navigation.state;
    return (
      <View>
        <Text>Chat with {params.user}</Text>
      </View>
    );
  }
}

export default class HomeScreen extends Component{
  static navigationOptions = {
    title: 'Welcome',
  };
  render(){
    const {navigate} = this.props.navigation;
    return( 
      <View> 
        <Text>Hello, Chat App!</Text>
        <Button 
          onPress={() => navigate('Chat', {user: 'huage'})}
          title='Chat with huage'
        />
      </View> 
    )
  }
}
const SimpleApp = StackNavigator({
  Home: {screen: HomeScreen},
  Chat: {screen: ChatScreen},
}); 

2. Tab Navigators

export class ChatScreen extends Component {  
  render() { 
    return (
      <View>
        <Text style={{marginTop:20}}>Chat with huage</Text>
      </View>
    );
  }
}

export default class HomeScreen extends Component{ 
  render(){ 
    return( 
      <View> 
        <Text style={{marginTop:20}}>Hello, Chat App!</Text> 
      </View> 
    )
  }
}
const SimpleApp = TabNavigator({
  Home: {screen: HomeScreen},
  Chat: {screen: ChatScreen},
}); 

AppRegistry.registerComponent('thirtyDayOfReactNative', () => SimpleApp);
