react 原生 Material 顶部选项卡导航器滑动禁用取决于屏幕

Question

只想禁用 Map 组件滑动，但在使用“swipeEnabled”时应用了整个屏幕。
我能怎么做？

const Tab = createMaterialTopTabNavigator();

const Tabs = () => {

  return (
    <Tab.Navigator
      swipeEnabled={false}  // <- Screens can be swiped but it is applied to every screen.
      {...}
    >
      <Tab.Screen
        name="Home"
        component={Home}
      />
      <Tab.Screen
        name="Map"
        component={Map}
      /> 
    </Tab.Navigator>
  );
}

const App = () => {
  return (
    <NavigationContainer>
      <SafeAreaView style={styles.safeAreaView} />
      <Tabs />
    </NavigationContainer>
  );
}

您可以将状态值传递给 swipeEnabled并将值更新为 false如果您在 Map画面是这样的:

const Tab = createMaterialTopTabNavigator();

const Tabs = () => {
  const [swipeEnabled, setSwipeEnabled] = useState(true);
  return (
    <NavigationContainer>
      <Tab.Navigator
        swipeEnabled={swipeEnabled}
        screenOptions={({ navigation, route }) => {
          if (route.name === 'Map' && navigation.isFocused()) {
            setSwipeEnabled(false);
          } else if (route.name !== 'Map' && navigation.isFocused()) {
            setSwipeEnabled(true);
          }
        }}>
        <Tab.Screen name="Home" component={Home} />
        <Tab.Screen name="Map" component={Map} />
      </Tab.Navigator>
    </NavigationContainer>
  );
};
