重置DrawerNavigator v.5中的嵌套StackNavigator

Question

在版本4中，我使用内容内的DrawerItems onItemPress重置了StackNavigation组件：

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有一个全新的API，所以我以前的重置代码不起作用。如何在DrawerNavigator v.5中执行此操作？

Answer 1

这对我有效，基于文档：

import { CommonActions } from "@react-navigation/native";
props.navigation.dispatch({
...CommonActions.reset({
index: 0,
routes: [{ name: "AuthStackNavigator" }]
})
});

如果你想在Stacknavigator中重置到特定的屏幕，你可以这样做：

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

我希望这能帮助到别人。

在react-navigation-v5中使用drawerContent而不是contentComponent简单编码；

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