const SignedOutRouteConfig = {
  [LOGIN]: { screen: LoginScreen },

const SignedInRouteConfig = {
  [HOME]: { screen: HomeScreen },
  [FEEDS]: { screen: FeedsScreen },

const SignedOut = StackNavigator(SignedOutRouteConfig, navigationOptions);
const SignedIn = StackNavigator(SignedInRouteConfig, navigationOptions);

const createRootNavigator = (signedIn: boolean = false) => StackNavigator(

    [SIGNED_IN]: {
      screen: SignedIn,
      navigationOptions: {
        gesturesEnabled: false,

  },
  {
    initialRouteName: signedIn ? SIGNED_IN : SIGNED_OUT,
  }
);

export default createRootNavigator;

如何将 header 内容居中并从顶部删除不必要的 space？

P.S 我已经尝试将高度设置为 headerStyle

Answer 1

尝试将此代码放入您的 App.js 文件中：

import { SafeAreaView } from "react-navigation";

if (Platform.OS === "android") {
  // removes extra space at top of header on android
  SafeAreaView.setStatusBarHeight(0);
}

Answer 2

在我的案例中 headerMode: 'none' 解决了这个问题。可能会有帮助

const Routes = createStackNavigator(
    {
      Login: { screen: Login,  },

      // Profile: { screen: ProfileScreen },
    },
    {
        // initialRouteName: 'Login',
        headerMode: 'none'
    }
);

Answer 3

您可以在 navigationOptions 中设置 headerForceInset: { top: 'never', bottom: 'never' }，这将删除 paddingTop。

Answer 4

如果你使用带有半透明选项的 StatusBar，你需要在 Stack.Navigator 上的 screenOptions 中使用选项 headerStatusBarHeight: 0

<Stack.Navigator
  screenOptions={{
    headerStatusBarHeight: 0,
  }}
