前言

大家应该都有所体会，我们在一般应用都有跨tab跳转的需求， 这就需要特别处理下路由，所以 下面是使用react-navigation作为路由组件的一种方式.

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 Home push HomeTwo, HomeTwo push BillTwo, BillTwo 返回到 Bill账单首页.

方法如下：

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},styles.icon]}/>), }, } }, Me: { screen: Me, path:'app/me', navigationOptions: { tabBar: { label: '我', icon: ({tintColor}) => (<Image source={require('./images/me.png')} style={[{tintColor: tintColor},styles.icon]}/>), }, } } }, { 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 BillTwothis.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HomeTwo push 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.
