Question

我正尝试从我的一个名为“个人资料”的标签中打开抽屉，如下所示。当我单击配置文件选项卡时，它将从ProfileNavigator打开主屏幕。没错，但是我想防止这种情况，只打开抽屉而没有默认导航。我该怎么做？另外，ProfileNavigator阻止打开我的下一个选项卡，即“主页”，为什么？但是我可以在Histroy屏幕上选择标签，然后可以返回到主屏幕。

const ProfileNavigator = createDrawerNavigator({
  Home: {
    screen: HomeScreen,
  },
  Notifications: {
    screen: ExampleScreen,
  }
});

const DashboardTabNav = createBottomTabNavigator({
  Profile: {
    screen: ProfileNavigator,
    navigationOptions: ({navigation}) => ({
      tabBarOnPress: (tab) => {
        navigation.openDrawer();
      }
    })
  },
  Home: Dashboard,
  History: SettingsScreen,
  Cart: CartScreen
})

啊，修复它。如果有人找一个例子，您需要在createBottomTabNavigator中添加createDrawerNavigator。反之，我正在这样做。例如，

const ProfileNavigator = createDrawerNavigator({
  Drawer: DashboardTabNav
}, {
  initialRouteName: 'Drawer',
  contentComponent: ExampleScreen,
  drawerWidth: 300

});

// Manifest of possible screens
const PrimaryNav = createStackNavigator({
  DashboardScreen: { screen: ProfileNavigator },
  LoginScreen: { screen: LoginScreen },
  LaunchScreen: { screen: LaunchScreen },
  UpdateUserScreen: { screen: UpdateUserScreen }
}, {
  // Default config for all screens
  headerMode: 'none',
  initialRouteName: 'LoginScreen',
  navigationOptions: {
    headerStyle: styles.header
  }
});
export default createAppContainer(PrimaryNav);

如何在不从tabnavigator的选项卡之一导航到屏幕的情况下打开抽屉？
