我查看了您的零食博览会，问题在于这段代码

 if (props.navigation.state.index === 0) {
                            props.navigation.navigate('DrawerOpen')
                        } else {
                            props.navigation.navigate('DrawerClose')
                        }

导航不会向状态添加索引，因此其值保持未定义

所以你要做的就是自己打开和关闭抽屉

因此，请删除此代码段以查看其工作情况

onPress={() => props.navigation.navigate('DrawerOpen')}

在2.0版本发布后，您现在可以调用navigation.openDrawer，而不是使用navigation.navigate“DrawerRopen”打开抽屉

其他方法有closeDrawer和toggleDrawer。

是的，我实际上已经知道了：。非常感谢。
