> [!WARNING] 使用时 import 的库名不变。

```js
import React, { useState } from 'react';
import { View, Text, Button, StyleSheet } from 'react-native';
import Localize from 'react-native-localization';

// 定义本地化内容
const strings = new Localize({
  en: {//英语
    welcome: 'Welcome',
    question: 'I\'d like some {0} and {1}, or just {0}',
    bread: 'bread',
    butter: 'butter',
    greeting: 'Hello, {0}!   ',
    currentlanguage: 'Current Language',
    availableLanguages: 'Available Languages',
    interfaceLanguage: 'The System Language'
  },
  fr: {//法语
    welcome: 'Bienvenue',
    question: 'Je voudrais un peu de {0} et {1}, ou juste {0}',
    bread: 'pain',
    butter: 'beurre',
    greeting: 'Bonjour, {0}!',
    currentlanguage: 'Langue actuelle',
    availableLanguages: 'Langues disponibles',
    interfaceLanguage: 'Langue du système'
  },
  bo: {//藏语
    welcome: 'བསྐུལ་མཁན།',
    question: 'ང་ལུས་འདི་ལས། {0} དང། {1} ཡང་ཡིན། གང་ཡིན་ནི། {0}',

    availableLanguages: 'ད་དུས་ལག་འཁྱེར་སྒྲིགས།',
    interfaceLanguage: 'རྩམ་གཞི་སྒྲིག་ལེན་དེ་རྒྱལ་སྤོད་'
  },
  zh: {//中文
    welcome: '欢迎',
    question: '我想要一些{0}和{1}，或者只要{0}',
    bread: '面包',
    butter: '黄油',
    greeting: '你好, {0}!',
    currentlanguage: '当前语言',
    availableLanguages: '当前可用语言列表',
    interfaceLanguage: '当前系统语言'
  },
});

export function LocalizationDemo() {
  // getLanguage API
  const [language, setLanguage] = useState(strings.getLanguage());
  const changeLanguage = (lang: string) => {
    // setLanguage API
    strings.setLanguage(lang);
    setLanguage(strings.getLanguage());
  };

  return (
    <View style={styles.screen}>
      <View style={{ height: 180, justifyContent: 'space-between', marginBottom: 30 }}>
        <Button
          color="#144400"
          title="切换成中文"
          onPress={() => changeLanguage('zh')}
        />
        <Button
          color="#841584"
          title="切换成法语"
          onPress={() => changeLanguage('fr')}
        />
        <Button
          color="#645555"
          title="切换成英语"
          onPress={() => changeLanguage('en')}
        />
        <Button
          color="#241595"
          title="切换成藏语"
          onPress={() => changeLanguage('bo')}
        />
      </View>

      <Text style={styles.text}>
        {strings.welcome}
      </Text>
      <Text style={styles.text}>
        {/* formatString API */}
        {strings.formatString(strings.question, strings.bread, strings.butter)}
      </Text>
      <Text style={styles.text}>
        {strings.currentlanguage}: {language}
      </Text>
      {/* getAvailableLanguages API */}
      <Text style={styles.text}>
        {strings.availableLanguages}: {strings.getAvailableLanguages().join(', ')}
      </Text>
      {/* getInterfaceLanguage API */}
      <Text style={styles.text}>
        {strings.interfaceLanguage}: {strings.getInterfaceLanguage()}
      </Text>
    </View>
  );
}

const styles = StyleSheet.create({
  text: {
    fontSize: 18,
    marginBottom: 10,
    color: 'white'
  },

  screen: {
    flex: 1,
    padding: 4,
    paddingTop: 10,
    backgroundColor: 'black',
    marginHorizontal: 4,
    marginVertical: 8,
    paddingHorizontal: 8,
  },
});
```
## 使用 Codegen

本库已经适配了 `Codegen` ，在使用前需要主动执行生成三方库桥接代码，详细请参考[ Codegen 使用文档](/zh-cn/codegen.md)。

## Link

目前鸿蒙暂不支持 AutoLink，所以 Link 步骤需要手动配置。

首先需要使用 DevEco Studio 打开项目里的鸿蒙工程 `harmony`

### 1.在工程根目录的 `oh-package.json5` 添加 overrides字段

```json
{
  ...
  "overrides": {
    "@rnoh/react-native-openharmony" : "file:./react_native_openharmony"
  }
}
```

### 2.引入原生端代码

目前有两种方法：

1. 通过 har 包引入（在 IDE 完善相关功能后该方法会被遗弃，目前首选此方法）；
2. 直接链接源码。

方法一：通过 har 包引入（推荐）

> [!TIP] har 包位于三方库安装路径的 `harmony` 文件夹下。

打开 `entry/oh-package.json5`，添加以下依赖

```json
"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@ohmi/react-native-localization": "file:../../node_modules/@ohmi/react-native-localization/harmony/react_localization.har"
  }
```

点击右上角的 `sync` 按钮

或者在终端执行：

```bash
cd entry
ohpm install
```
方法二：直接链接源码

> [!TIP] 如需使用直接链接源码，请参考[直接链接源码说明](/zh-cn/link-source-code.md)


### 3.在 ArkTs 侧引入 RNReactLocalizationPackage

打开 `entry/src/main/ets/RNPackagesFactory.ts`，添加：

```diff
  ...
+ import { RNReactLocalizationPackage } from '@ohmi/react-native-localization';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new SamplePackage(ctx),
+   new RNReactLocalizationPackage(ctx),
  ];
}
```

### 4.配置 CMakeLists 和引入 RNAmapGeolocationPackage

打开 `entry/src/main/cpp/CMakeLists.txt`，添加：

```diff
project(rnapp)
cmake_minimum_required(VERSION 3.4.1)
set(CMAKE_SKIP_BUILD_RPATH TRUE)
set(RNOH_APP_DIR "${CMAKE_CURRENT_SOURCE_DIR}")
set(NODE_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../node_modules")
+ set(OH_MODULES "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
set(RNOH_CPP_DIR "${CMAKE_CURRENT_SOURCE_DIR}/../../../../../../react-native-harmony/harmony/cpp")
set(LOG_VERBOSITY_LEVEL 1)
set(CMAKE_ASM_FLAGS "-Wno-error=unused-command-line-argument -Qunused-arguments")
set(CMAKE_CXX_FLAGS "-fstack-protector-strong -Wl,-z,relro,-z,now,-z,noexecstack -s -fPIE -pie")
set(WITH_HITRACE_SYSTRACE 1) # for other CMakeLists.txt files to use
add_compile_definitions(WITH_HITRACE_SYSTRACE)

add_subdirectory("${RNOH_CPP_DIR}" ./rn)

# RNOH_BEGIN: manual_package_linking_1
add_subdirectory("../../../../sample_package/src/main/cpp" ./sample-package)
+ add_subdirectory("${OH_MODULES}/@ohmi/react-native-localization/src/main/cpp" ./react_localization)
# RNOH_END: manual_package_linking_1

file(GLOB GENERATED_CPP_FILES "./generated/*.cpp")

add_library(rnoh_app SHARED
    ${GENERATED_CPP_FILES}
    "./PackageProvider.cpp"
    "${RNOH_CPP_DIR}/RNOHAppNapiBridge.cpp"
)
target_link_libraries(rnoh_app PUBLIC rnoh)

# RNOH_BEGIN: manual_package_linking_2
target_link_libraries(rnoh_app PUBLIC rnoh_sample_package)
+ target_link_libraries(rnoh_app PUBLIC rnoh_localization)
# RNOH_END: manual_package_linking_2
```

打开 `entry/src/main/cpp/PackageProvider.cpp`，添加：

```diff
#include "RNOH/PackageProvider.h"
#include "generated/RNOHGeneratedPackage.h"
#include "SamplePackage.h"
+ #include "RNLocalizationPackage.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
        std::make_shared<RNOHGeneratedPackage>(ctx),
        std::make_shared<SamplePackage>(ctx),
+       std::make_shared<RNLocalizationPackage>(ctx),
    };
}
```

### 5.运行

点击右上角的 `sync` 按钮

或者在终端执行：

```bash
cd entry
ohpm install
```

然后编译、运行即可。

## 约束与限制

### 兼容性

要使用此库，需要使用正确的 React-Native 和 RNOH 版本。另外，还需要使用配套的 DevEco Studio 和 手机 ROM。
