react-navigation跨tab路由处理

一般应用都有跨tab跳转的需求,这就需要特别处理下路由. 下面是使用React-navigation作为路由组件的一种方式.http://www.bijishequ.com/detail/369321

具体情境是: app分三大模块Home主页,Bill账单和Me我的,对应三个tab. 现在需求是HomepushHomeTwo,244);">HomeTwopushBillTwo,244);">BillTwo返回到Bill账单首页.

首先选择路由结构,选择使用最外层是StackNavigator,然后包含3个TabNavigator和其他组件.

const Components = {
    HomeTwo: { screen: HomeTwo,path:'app/HomeTwo' },HomeThree: { screen: HomeThree,path:'app/HomeThree' },BillTwo: { screen: BillTwo,path:'app/BillTwo' },BillThree: { screen: BillThree,path:'app/BillThree' },}

const Tabs = TabNavigator({
     Home: {
         screen: Home,path:'app/home',navigationOptions: { 
             tabBar: {
                 label: '首页',icon: ({tintColor}) => (<Image source={require('./images/home.png')} style={[{tintColor: tintColor},styles.icon]}/>),},}
     },Bill: {
         screen: Bill,path:'app/bill',navigationOptions: {
             tabBar: {
                 label: '账单',icon: ({tintColor}) => (<Image source={require('./images/bill.png')} style={[{tintColor: tintColor},Me: {
         screen: Me,path:'app/me',navigationOptions: {
             tabBar: {
                 label: '我',icon: ({tintColor}) => (<Image source={require('./images/me.png')} style={[{tintColor: tintColor},}
     }
   },{
       tabBarPosition: 'bottom',swipeEnabled: false,animationEnabled: false,lazyLoad: false,backBehavior: 'none',tabBarOptions: {
           activeTintColor: '#ff8500',inactiveTintColor: '#999',showIcon: true,indicatorStyle: {
               height: 0  
           },style: {
               backgroundColor: '#fff',labelStyle: {
               fontSize: 10,});


 const Navs = StackNavigator({
     Home: { screen: Tabs,path:'app/Home' },Bill: { screen: Tabs,path:'app/Bill' },Me: { screen: Tabs,path:'app/Me' },...Components
 },{
        initialRouteName: 'Home',navigationOptions: { 
            header: {  
                style: {
                    backgroundColor: '#fff'
                },titleStyle: {
                    color: 'green'
                }
            },cardStack: { 
                gesturesEnabled: true
            }
        },mode: 'card',headerMode: 'screen'
 });

在HomeTwo里使用react-navigation自带的reset action就可以重置路由信息了:

// push BillTwo
this.props.navigation.dispatch(resetAction);

// 使用reset action重置路由
const resetAction = NavigationActions.reset({
    index: 1,// 注意不要越界
    actions: [  // 栈里的路由信息会从 Home->HomeTwo 变成了 Bill->BillTwo
        NavigationActions.navigate({ routeName: 'Bill'}),NavigationActions.navigate({ routeName: 'BillTwo'})
    ]
});

从HomeTwopush 到BillTwo页面后,点击BillTwo的左上角导航按钮返回就能返回到Bill账单首页了.

react-navigation自带的Bill账单首页了.
