复杂的 React 导航状态

Question

我想在我的 React Native 应用程序中使用 React Navigation，但我不确定如何获得这个特定功能： Demo from Samsung Health，其中有一个底部选项卡导航器，并且在每个选项卡屏幕的标题中都有一个菜单按钮，可以打开抽屉导航器，并且抽屉导航器中的每个选项都会打开一个堆栈导航器（所有选项卡都相同） ，即“主页”选项卡“为你”按钮打开与“在一起”选项卡完全相同的“为你”屏幕等）

我尝试了 stackNavigator、drawerNavigator 和 bottomTabNavigator 的各种组合，但没有一个以合理的方式运行，或者至少以我想要的方式运行。我做了一个基本的bottomTabNavigator，但我不知道在哪里放drawerNavigator；

const HomeStack = createStackNavigator({
  Home: HomeScreen
});
const NotifyStack = createStackNavigator({
  Notify: NotifyScreen
});
const ProfileStack = createStackNavigator({
  Profile: ProfileScreen
});
const SettingsStack = createStackNavigator({
  Settings: SettingsScreen
});

const DrawerStack1 = createStackNavigator({
  DrawerStack: DrawerScreen1
});
const DrawerStack2= createStackNavigator({
  DrawerStack: DrawerScreen2
});
const DrawerStack3 = createStackNavigator({
  DrawerStack: DrawerScreen3
});


const Drawer = createDrawerNavigator({
  DrawerStack1,
  DrawerStack2,
  DrawerStack3
});

const AppBottomTabs = createMaterialBottomTabNavigator({
  Home: HomeStack,
  Notify: NotifyStack,
  Profile: ProfileStack,
  Settings: SettingsStack
});

我为您创建了示例项目，其中每个选项卡中有 3 个选项卡和抽屉。抽屉有选项（事件，ForYou），将打开单独的屏幕
