【水滴石穿】bstmy-blend-app

这个项目是一个简单的底部导航切换页面

项目的地址为：https://github.com/Bstmy/bstmy-blend-app

先看效果



点击首页是首页面，点击个人中心是个人中心页面

先看代码

//index.js
//引用的是根app.js
import {AppRegistry} from 'react-native';
import App from './app/App';
import {name as appName} from './app.json';
AppRegistry.registerComponent(appName, () => App);

//app/App.js
//这个里面不仅有防止闪屏的，还有倒计时为3的启动页，还有定义了首页
import React, { Component } from 'react';
//闪屏
import SplashScreen from 'react-native-splash-screen';
//导航
import {createAppContainer, createStackNavigator} from 'react-navigation';

//显示首页
import Home from "./Home";
//这个是很好看的启动页很美腻
import GuideView from "./guide/GuideView";
const RootStack = createStackNavigator(
    {
        homes: Home,
        guideView: GuideView
    },
    {
        initialRouteName: 'guideView'   ,
        defaultNavigationOptions: {
            headerStyle: {
                backgroundColor: '#f4511e',
                height:0,
            },
            headerTintColor: '#fff',
            headerTitleStyle: {
                fontWeight: 'bold',
            },
        },
    }
);
const AppContainer = createAppContainer(RootStack);
//定义首页
//渲染AppConta
export default class App extends Component {

    constructor(props) {
        super(props);
        SplashScreen.hide(); // 关闭启动屏幕
    }

    render() {
        return (
            <AppContainer />
        );
    }

}

//app/guide/GuideView.js
//配置的启动页
import React, {Component} from 'react';

            this.setState(previousState => {
                return {invertedTime: (previousState.invertedTime-1)};
            })
            console.log("启动倒计时"+this.state.invertedTime );
            if(this.state.invertedTime == 0){
                this.openHomePage();
                clearInterval(this.timer1)
            }
        } ,1000);
    }
    openHomePage(){

                <Swiper style={styles.wrapper}
                    showsButtons={false}       //为false时不显示控制按钮

                    loop={true}        //如果设置为false，那么滑动到最后一张时，再次滑动将不会滑到第一张图片。
                    autoplay={true}          //自动轮播
                    autoplayTimeout={3}      //每隔3秒切换
                    >

        flexDirection: 'column',

        top: 20,
    }
});

export default GuideView;

//app/utils/AutoSize.js
//这个里面进行的就是屏幕适配
import React from 'react';
import Dimensions from 'Dimensions';

const AutoSize = {
    size: {
        width: Dimensions.get('window').width,
        height: Dimensions.get('window').height
    },

export default AutoSize;

//app/route/RootStack.js
//定义的是首页

export const RootStack = createStackNavigator(

    {
        initialRouteName: 'guideView',
        defaultNavigationOptions: {
            headerStyle: {

            headerTitleStyle: {
                fontWeight: 'bold',
            },
        },
    }
);

//和index页面类似，不过具体怎么控制的？
//app/pages/User.js
import React, { Component } from 'react';

import {
    View,
    Text
} from 'react-native';

class User extends Component {

    render() {
        return (
            <View>

                <Text>
                    我是用户
                </Text>

            </View>
        );
    }
}

export default User;

上面有一点点的不理解

不知道是什么控制的切换的页面的，因为那个是同时引用的

不过这个项目我喜欢～～哭唧唧，在这个水平这里～～
