如何使用drawerNavigation [react-navigation] [react-native]锁定特定页面的抽屉

Question

这是我的抽屉导航：

const DashboardStack = StackNavigator({
        Dashboard: {
            screen: Dashboard
        },
    }, {
        headerMode: 'screen',
    });

const DetailsformStack = StackNavigator({
    Detailsform: {
        screen: Detailsform
    },
}, {
    headerMode: 'none'
});

const OtpStack = StackNavigator({
    Otp: {
        screen: Otp,
        drawer: {
            lockMode: 'locked-closed'
        }
    },
    }, {
        headerMode: 'none'
});

const MobilenumberStack = StackNavigator({
    Mobilenumber: {
        screen: Mobilenumber
    },
}, {
    headerMode: 'none'
});

const DrawerviewStack = StackNavigator({
    Drawerview: {
        screen: Drawerview
    },
}, {
    headerMode: 'none'
});

const ExamsheetStack = StackNavigator({
    Examsheet: {
        screen: Examsheet
    },
}, {
    headerMode: 'none'
});

const TopicStack = StackNavigator({
    Topic: {
        screen: Topic
    },
}, {
    headerMode: 'screen'
});

const DrawerStack = DrawerNavigator({
    Otp: {
        screen: OtpStack,
    },
    Dashboard: {
        screen: DashboardStack,
    },
    Detailsform: {
        screen: DetailsformStack,
    },
    Mobilenumber: {
        screen: MobilenumberStack,
    },
    Drawerview: {
        screen: DrawerviewStack,
    },
    Examsheet: {
        screen: ExamsheetStack,
    },
    Topic: {
        screen: TopicStack,
    }
}, {
    headerMode: 'none',
    initialRouteName: 'Mobilenumber',
    contentComponent: Drawerview,

    lockMode: 'locked-closed'
});

如何将锁定模式lockMode添加到特定页面。

我尝试在组件页面和drawerNavigation页面中添加drawer: {lockMode: 'locked-closed'}，但它不起作用。

反应导航是否具有锁定模式功能还是需要禁用滑动手势？

如果没有功能，请告诉我如何禁用特定组件或页面的滑动手势。

Answer 1

martnu为此给了一个patch，但尚未合并。我尝试手动修补它并且工作得很好。

它仅适用于两个文件的更改:(参考此页面https://github.com/react-community/react-navigation/pull/793/files）

1. 反应导航/ SRC / TypeDefinition.js，

将下面的代码复制到NavigationDrawerScreenOptions，在NavigationRouteConfigMap正上方，投入NavigationDrawerScreenOptions的声明：

drawerLockMode?: 'unlocked' | 'locked-close' | 'locked-open',

2. 反应导航/ SRC /视图/ DrawerView.js，

在函数返回之前将代码复制到render()中：

const options = this.props.router.getScreenOptions(
    addNavigationHelpers({
        state: this._screenNavigationProp.state,
        dispatch: this._screenNavigationProp.dispatch,
    }),
    this.props.screenProps,
);

并将以下代码复制到<DrawLayout>之后返回ref道具：

drawerLockMode={options.drawerLockMode || 'unlocked'}

用法：

您只需添加以下内容即可在任何屏幕上禁用抽屉：

navigationOptions: {
  drawerLockMode: 'locked-closed'
}

并启用抽屉：

navigationOptions: {
  drawerLockMode: 'unlocked'
}

Answer 2

我也在react-navigation v2上遇到过这个问题。正如在drawer docs中所写，解决方案可以是在路由初始化之后定义导航选项，并禁止在定义的路径中显示抽屉导航器。

我的路线看起来像

const RoutesStack = StackNavigator({
  Authentication: {
    screen: Authentication,
  },

并添加了选项，低于路线。

RoutesStack.navigationOptions = ({ navigation }) => {
 name = (navigation.state.index !== undefined ? navigation.state.routes[navigation.state.index] : navigation.state.routeName)
  let drawerLockMode = 'locked-closed'
  if (name.routeName != 'Authentication' && name.routeName != 'Signup') {
    drawerLockMode = 'unlocked'
  }

  return {
    drawerLockMode,
  };
}
