ReactNative——页面跳转

效果图:

 

进入工作目录,运行

react-native init NavigatorProject

创建项目NavigatorProject

 

 

import React, { Component } from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TouchableHighlight,
  Image,
  Navigator
} from 'react-native';

 

class navigatorProject extends Component{
    render(){
        let defaultName = 'firstPageName';
        let defaultComponent = FirstPageComponent;
        return(             <Navigator                 initialRoute = {{name: defaultName, component: defaultComponent}}  //初始化导航器Navigator,指定默认的页面                 configureScene = {                     (route) => {                         return Navigator.SceneConfigs.FloatFromRight;  //配置场景动画,页面之间跳转时候的动画                     }                 }                 renderScene = {                     (route, navigator) =>{                         let Component = route.component;                         return <Component{...route.params} navigator = {navigator} />  //渲染场景                     }                 }             />         );     } }

 

//第一个页面

class FirstPageComponent extends Component{
    clickJump(){
        const{navigator} = this.props;
        if(navigator){
            navigator.push({  //navigator.push 传入name和你想要跳的组件页面

                component: SecondPageComponent
            });
        }

    render(){
        return(

//第二个页面

        if(navigator){
            navigator.pop();  //navigator.pop 使用当前页面出栈, 显示上一个栈内页面.

const styles = StyleSheet.create({

    //接收传递过来的参数
