如何使用react-native-elements中的主题提供者标记包装appContainer？

Question

我需要用ThemeProvider标签封装我的应用程序主组件，但我不知道在哪里封装它，因为我使用的是来自react-navigation的appContainer，看起来我需要改为封装appContainer。

我在一个没有expo的react-native项目中工作。我正在导入反应原生元素和反应导航。我需要封装已经被appContainer包装的app.js

App.js

import { createSwitchNavigator, createStackNavigator, createAppContainer } from 'react-navigation';
import PantallaInicio from './components/home/PantallaInicio';
import PantallaLogin from './components/auth/PantallaLogin';
import PantallaRegistro from './components/auth/PantallaRegistro';
import PantallaCargando from './components/auth/PantallaCargando';

const AppStack = createStackNavigator({ Home: PantallaInicio, });
const AuthStack = createStackNavigator({ Login: PantallaLogin, Registro: PantallaRegistro });

export default createAppContainer(createSwitchNavigator(
  {
    AuthLoading: PantallaCargando,
    App: AppStack,
    Auth: AuthStack,
  },
  {
    initialRouteName: 'AuthLoading',
  }

));

index.js

/**
 * @format
 */

import {AppRegistry} from 'react-native';
import App from './src/App';
import {name as appName} from './app.json';

AppRegistry.registerComponent(appName, () => App);

很抱歉，我还没有任何输出，感谢您的时间。

Answer 1

createAppContainer返回React Component。因此，您可以使用任何provider对其进行包装。

import React from 'react';
import {AppRegistry} from 'react-native';
import App from './src/App';
import { ThemeProvider } from 'react-native-elements';
import theme from './your-theme';
import {name as appName} from './app.json';

const ProvidedApp = () => {
  return <ThemeProvider theme={theme} ><App /></ThemeProvider>
}

AppRegistry.registerComponent(appName, () => ProvidedApp);

我借用这个帖子是为了解决关于Jeff Gu Kang所说的一个问题..

Jeff Gu Kang：“你可以使用任何ThemeProvider”

我从react-native-elements中使用了<ThemeProvider/>，包装了createAppContainer返回的组件。主题道具可以是lightTheme och darkTheme对象，具体取决于lightThemeState。

使用screenProps，我向下发送了一个函数，屏幕组件可以使用该函数将主题从浅色更改为深色。但是屏幕不会更新...如果我将lightThemeNav的状态更改为false，所有内容都会更改并正常工作，但由于某些原因，当我切换按钮时，它不会更新主题。(按钮将正确更改状态)

代码如下：

const TabNavigator = createMaterialBottomTabNavigator(
  {
    FindDestinationScreen: {
      screen: FindDestinationScreen,
      navigationOptions: {
        title: "Search",
        tabBarIcon: ({ tintColor }) => (
          <SafeAreaView>
            <Icon
              style={[{ color: tintColor }]}
              size={25}
              name={"ios-search"}
            />
          </SafeAreaView>
        ),
      },
    },
  },
  {
    barStyleDark: {
      backgroundColor: "#212121",
      shadowColor: "#000",
      shadowOffset: { width: 3, height: 2 },
      shadowOpacity: 0.8,
      shadowRadius: 2,
      elevation: 1,
    },
    barStyleLight: {
      backgroundColor: "#3c5e82",
    },
    shifting: false,
    labeled: true,
    initialRouteName: "FindDestinationScreen",
    activeColor: "#E4DC93",
    inactiveColor: "#fff",
    barStyle: { backgroundColor: "transparent", height: 80, paddingTop: 10 },
  }
);

const AllRoutes = createSwitchNavigator(
  {
    PersonalSettings: {
      title: "Personal Settings",
      screen: PersonalSettings,
      header: ({ goBack }) => ({
        left: (
          <Icon
            name={"chevron-left"}
            onPress={() => {
              goBack();
            }}
          />
        ),
      }),
    },
    Tabs: {
      screen: TabNavigator,
    },
  },
  {
    initialRouteName: "Tabs",
  }
);

const AppContainer = createAppContainer(AllRoutes);

export default App = () => {
  const [lightThemeState, setLightThemeState] = useState(true);

  return (
      <ThemeProvider theme={lightThemeState ? lightTheme : darkTheme}>
        <AppContainer
          theme={lightThemeState ? "light" : "dark"}
          screenProps={{
            setLightThemeState: setLightThemeState,
          }}
        />
      </ThemeProvider>
  );
};

会非常感谢任何形式的帮助..谢谢!
