React Native Router Flux：从主场景导航到子场景

问题描述

• react-native-router-flux v3.35.0


• react-native v0.31

我的场景很少。其中一个场景的子场景很少。如何从一个主场景导航到其中一个子场景？

I have few scenes. one of scenes have few sub-scenes. how can i navigate to one of sub-scenes from one of main scenes?

示例：

<Router createReducer={reducerCreate} getSceneStyle={getSceneStyle}>
        <Scene key="root">
          <Scene key="login" direction="vertical" component={Login} title="Login" hideTabBar hideNavBar />
          <Scene key="tabbar" initial={show}>
            <Scene key="main" tabs tabBarStyle={styles.tabBarStyle} tabBarSelectedItemStyle={styles.tabBarSelectedItemStyle} tabBarIconContainerStyle={styles.tabBarIconContainerStyle} >
              <Scene key="courses" component={Courses} title="Courses" icon={IconCourses} navigationBarStyle={styles.navigationBarStyle} titleStyle={styles.titleStyle} initial />
              <Scene key="register"  component={Register} title="Register" icon={IconRegister} navigationBarStyle={styles.navigationBarStyle} titleStyle={styles.titleStyle} />
              <Scene key="schedule" component={Schedule} title="Schedule" icon={IconSchedule} navigationBarStyle={styles.navigationBarStyle} titleStyle={styles.titleStyle} />
              <Scene key="evaluation" component={Schedule} title="Evaluation" icon={IconEvaluation} navigationBarStyle={styles.navigationBarStyle} titleStyle={styles.titleStyle} />
              <Scene key="profile"
              component={Profile}
              title="Profile"
              icon={IconProfile}
              navigationBarStyle={styles.navigationBarStyle}
              titleStyle={styles.titleStyle}
              onLeft={() => { Actions.login(); }}
              leftTitle="Add Account"
              onRight={() => { Actions.login({type: 'reset'}); }}
              rightTitle="Logout"
              rightButtonTextStyle={styles.ButtonTextStyle}
              leftButtonTextStyle={styles.ButtonTextStyle}
              leftButtonStyle={styles.leftButtonStyle} />
            </Scene>
          </Scene>
          <Scene key="terms" component={Terms} />
          <Scene key="details" component={Details} title="Details" navigationBarStyle={styles.navigationBarStyle} titleStyle={styles.titleStyle} backButtonTextStyle={styles.backButtonTextStyle} hideTabBar />
        </Scene>
      </Router>

我想从详细信息导航到课程。但课程是另一个课程。我怎么能这样做？

I want to navigate from Details to Courses. but courses is a Tab under another. how can i do that?

我只能导航到tabbar场景，而不是课程或注册。

I can navigate only to tabbar scene, not courses or register.

推荐答案

我发现如果你首先导航到标签栏，你可以切换到内部标签，例如：

I've found that you can switch to inner tabs if you navigate to the tabbar first, e.g.:

<Button onPress={() => {
    Actions.tabbar({type:ActionConst.RESET});
    Actions.courses();
}} title="See Courses" />

第一个场景转换会将场景重置为标签栏，默认情况下会显示初始场景，第二个转换然后替换当前场景，因为react-native-router-flux处理标签场景转换的方式。

The first scene transition resets the scene to your tab bar, and would by default show your initial scene, the second transition then replaces your current scene due to how react-native-router-flux handles tab scene transitions.
