導覽組件react-navigation如何使用

這次帶給大家的是導航元件react-navigation如何使用，大家應該都有所體會，我們在一般應用都有跨tab跳轉的需求， 這就需要特別處理下路由，這篇文章就給大家好好分析一下。

特定情境是: app分三大模組Home首頁, Bill帳單和Me我的, 對應三個tab. 現在需求是 Home push HomeTwo, HomeTwo push BillTwo, BillTwo 返回到Bill賬單首頁.

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(&#39;./images/home.png&#39;)} style={[{tintColor: tintColor},styles.icon]}/>),
  },
  }
 },
 Bill: {
  screen: Bill,
  path:&#39;app/bill&#39;,
  navigationOptions: {
  tabBar: {
   label: &#39;账单&#39;,
   icon: ({tintColor}) => (<Image source={require(&#39;./images/bill.png&#39;)} style={[{tintColor: tintColor},styles.icon]}/>),
  },
  }
 },
 Me: {
  screen: Me,
  path:&#39;app/me&#39;,
  navigationOptions: {
  tabBar: {
   label: &#39;我&#39;,
   icon: ({tintColor}) => (<Image source={require(&#39;./images/me.png&#39;)} style={[{tintColor: tintColor},styles.icon]}/>),
  },
  }
 }
 }, {
 tabBarPosition: &#39;bottom&#39;, 
 swipeEnabled: false,
 animationEnabled: false, 
 lazyLoad: false, 
 backBehavior: &#39;none&#39;, 
 tabBarOptions: {
  activeTintColor: &#39;#ff8500&#39;, 
  inactiveTintColor: &#39;#999&#39;,
  showIcon: true, 
  indicatorStyle: {
  height: 0 
  },
  style: {
  backgroundColor: &#39;#fff&#39;, 
  },
  labelStyle: {
  fontSize: 10, 
  },
 },
 });
  
  
 const Navs = StackNavigator({
 Home: { screen: Tabs, path:&#39;app/Home&#39; },
 Bill: { screen: Tabs, path:&#39;app/Bill&#39; },
 Me: { screen: Tabs, path:&#39;app/Me&#39; },
 ...Components
 }, {
 initialRouteName: &#39;Home&#39;, 
 navigationOptions: { 
  header: { 
  style: {
   backgroundColor: &#39;#fff&#39;
  },
  titleStyle: {
   color: &#39;green&#39;
  }
  },
  cardStack: { 
  gesturesEnabled: true
  }
 },
 mode: &#39;card&#39;, 
 headerMode: &#39;screen&#39;
 });

在HomeTwo裡使用react-navigation自帶的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'})
 ]
});

從HomeTwo push到BillTwo頁面後, 點擊BillTwo的左上角導航按鈕返回就能返回到Bill賬單首頁了.
