折腾:

【已解决】ReactNative的导航库:native-navigation vs react-native-navigation

决定用:native-navigation

去参考:

Navigating Between Screens – React Native

Hello Mobile Navigation | React Navigation

安装:

➜  rn_rse npm install –save react-navigation
npm WARN gentlyRm not removing /Users/crifan/dev/dev_root/daryun/Projects/xxxsourcecode/react_native/rn_rse/rn_rse/node_modules/metro-bundler/node_modules/.bin/json5 as it wasn’t installed by /Users/crifan/dev/dev_root/daryun/Projects/xxxrn_rse/node_modules/metro-bundler/node_modules/json5

added 8 packages, removed 1073 packages and updated 20 packages in 54.585s

结果期间出错:

【已解决】npm start出错:react-native-scripts: command not found

 然后用代码:

App.js

import React from ‘react’;
import { StackNavigator } from ‘react-navigation’;
import Home from ‘./Home’;
import Profile from ‘./Profile’;
const RseApp = StackNavigator({
  Home: { screen: Home },
  Profile: { screen: Profile },  
});
export default class App extends React.Component {
  render() {
    return <RseApp />;
  }
}

Home.js

import React from ‘react’;
import {
  StyleSheet,
  Text,
  View,
  TextInput,
  Button
} from ‘react-native’;
import { StackNavigator } from ‘react-navigation’;
import Profile from ‘./Profile’;
export default class Home extends React.Component {
  static navigationOptions = {
    title: ‘主页标题’,
  };
  constructor(props) {
    super(props);
  }
  render() {
    const { navigate } = this.props.navigation;
    return (
      <View style={styles.container}>
        <Text>主页内容</Text>
        <Button
          onPress={() => navigate(‘Profile’, { user: ‘Crifan Li’ })}
          title="跳转到Profile页"
        />
      </View>
    );
  }
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: ‘#fff’,
    alignItems: ‘center’,
    justifyContent: ‘center’,
  },
});

Profile.js

import React from ‘react’;
import {
  StyleSheet,
  Text,
  View,
  TextInput,
  Button
} from ‘react-native’;
import { StackNavigator } from ‘react-navigation’;
export default class Profile extends React.Component {
  static navigationOptions = ({ navigation }) => ({
    title: `个人中心:${navigation.state.params.user}`,
  });
  constructor(props) {
    super(props);
  }
  render() {
    const { navigate } = this.props.navigation;
    // The screen’s current route is passed in to `props.navigation.state`:
    const { params } = this.props.navigation.state;
    
    return (
      <View style={styles.container}>
        <Text>当前用户:{params.user}</Text>
        <Button
          onPress={() => navigate(‘Home’)}
          title="跳回Home页"
        />
      </View>
    );
  }
}
const styles = StyleSheet.create({
  container: {
    flex: 1,
    backgroundColor: ‘#fff’,
    alignItems: ‘center’,
    justifyContent: ‘center’,
  },
});

效果:

所以就需要去解决:

【已解决】react-navigation导航栏被状态栏遮盖挡住了一部分

react-navigation的TabNavigator设置bottom,实现底部的tab,但是:

然后,再去试试底部的tab:

参考:

TabNavigator | React Navigation

不过先要去找点tab的图标:

【已解决】ReactNative中使用icon图标

去尝试期间出错:

【基本解决】react-navigation用TabNavigator出错:undefined is not an object evaluating params.user

然后可以看到icon是可以生效的。

再去试试别的icon:

但是后来发现,同样的代码,在iOS和android上,效果还是有不少差别的:

iPhone6,底部tab的高度比较合适,大概估计就49

而Android中,高分屏中,底部tab的高度好像很高,估计有60+:
