我正在使用反应导航,我想从我的个人资料屏幕打开一个抽屉,可以选择进入 EditProfile 屏幕和设置 >屏幕。但是,当我点击 MyProfile的标题按钮时,我不知道如何打开抽屉。
App.js:
const MyProfileStack = createStackNavigator({
MyProfile: {
screen: profile,
navigationOptions: ({navigation}) => {
return {
title: "My Profile",
headerRight: (
<Icon type="evilicon" name="navicon" size={40}
onPress={() => navigation.dispatch(DrawerActions.openDrawer())}/>
)
};
}
}
})
const DrawerStack = createDrawerNavigator({
Edit: { screen: EditProfileStack }
Settings: { screen: SettingsStack }
})
const EditProfileStack = createStackNavigator({
EditProfile: {
screen: editProfile,
navigationOptions: ({navigation}) => {
return {
title: "Edit Profile",
headerLeft: (
<Icon type="evilicon" name="chevron-left" size={50}
onPress={() => navigation.navigate("MyProfile")}/>
)
};
}
}
});
const TabStack = createBottomTabNavigator({
Feed: { screen: FeedStack },
Profile: { screen: MyProfileStack },
});
const MainStack = createSwitchNavigator(
{
Home: TabStack,
Drawer: DrawerStack
},
{
initialRouteName: 'Home'
}
);
const AppContainer = createAppContainer(MainStack);

解决方案
您需要将MyProfileStack
放在DrawerStack
中,如下所示。
const DrawerStack = createDrawerNavigator({
MyProfile: { screen: MyProfileStack }
Edit: { screen: EditProfileStack }
Settings: { screen: SettingsStack }
})
const TabStack = createBottomTabNavigator({
Feed: { screen: FeedStack },
Profile: { screen: DrawerStack },
});
const AppContainer = createAppContainer(MainStack);
您可以使用各种组合。
当您切换到另一个屏幕时,SwitchNavigator会退出其他屏幕。因此,您无法从已经辞职的屏幕中调用抽屉。
p.s:如果要在更改屏幕时刷新屏幕,则可以使用navigation events。使用onWillFocus
。
