创建视图层

学习前先查看项目结构:https://github.com/zhouwei1994/nativeCase/blob/master/README.md

在项目src/components/common目录下创建 RootView.js

import React, { Component } from "react";
import { StyleSheet, AppRegistry, View, Text } from 'react-native';
import Loading from './Loading';
import Toast from './Toast';
import Popup from './Popup';
const originRegister = AppRegistry.registerComponent;
AppRegistry.registerComponent = (appKey, component) => {
    return originRegister(appKey, function () {
        const OriginAppComponent = component();
        return class extends Component {
            render() {
                return (
                    
                        
                        {/* 弹窗 */}
                        
                        {/* 提示 */}
                        
                        {/* //加载动画 */}
                        
                    
                );
            };
        };
    });
};
const styles = StyleSheet.create({
    container: {
        flex: 1,
        position: 'relative',
    },
});

在src/App.js里面

import React, { Component } from 'react';
import { ToastAndroid, BackHandler, StatusBar } from 'react-native';
import { Provider } from 'react-redux';
import { store, AppWithNavigationState } from './store/index';
//引入创建的RootView文件
import "./components/common/RootView";
export default class Root extends React.Component {
  render() {
    return (
      
        
      
    );
  }
}
