Question

在版本4中，我在contentComponent内使用DrawerItems onItemPress重置了StackNavigation：

const AppDrawerNavigator = createDrawerNavigator(
  {
    Stack1: {
       screen: Stack1,
       navigationOptions: { // options}
   },
   Stack2: {
      screen: Stack2,
      navigationOptions: { // options}
   },
  {
    initialRouteName: 'Stack1',
    contentOptions: {
      activeTintColor: '#346bc7',
    },
    contentComponent: props => {
      return (
        <ScrollView>
          <SafeAreaView forceInset={{ top: 'always', horizontal: 'never' }} >
            <DrawerItems {...props} onItemPress={router => {
              const navigateAction = NavigationActions.navigate({
                routeName: router.route.routeName,
                params: {},
                action: NavigationActions.navigate({ routeName: router.route.routes[0].routeName }),
              });
              props.navigation.dispatch(navigateAction);
            }}
            />
          </SafeAreaView>
        </ScrollView>
      )
    }
  },
);

React Navigation 5具有一个全新的API，因此旧的重置代码无法正常工作。如何在DrawerNavigator v.5中做到这一点？

Answer 1

基于documentation，这对我有用：

import { CommonActions } from "@react-navigation/native";

 props.navigation.dispatch({
      ...CommonActions.reset({
        index: 0,
        routes: [{ name: "AuthStackNavigator" }]
      })
    });

如果您想在该Stacknavigator中重置为特定屏幕，可以执行以下操作：

  props.navigation.dispatch({
      ...CommonActions.reset({
        index: 0,
        routes: [
          {
            name: "AuthStackNavigator",
            state: {
              routes: [
                {
                  name: "SignUpScreen",
                  params: {         //<--- send with param optional
                    paramTest: "param test"
                  }
                }
              ]
            }
          }
        ]
      })
    });

我希望这可以帮助某人。

您在react-navigation-v5中使用抽屉内容而不是contentComponent 简单地编码；

<Drawer.Navigator drawerContent={props => <DrawerCustomComponent {...props} />}>
     {{ screen objects }}
</Drawer.Navigator>
