安装与使用

请到三方库的 Releases 发布地址查看配套的版本信息:@react-native-oh-tpl/react-native-localize Releases 。对于未发布到npm的旧版本,请参考安装指南安装tgz包。

进入到工程目录并输入以下命令:

npm

npm install @react-native-oh-tpl/react-native-localize

yarn

yarn add @react-native-oh-tpl/react-native-localize

下面的代码展示了这个库的基本使用场景:

[!WARNING] 使用时 import 的库名不变。

import * as React from "react";
import {
  I18nManager,
  Platform,
  SafeAreaView,
  ScrollView,
  StyleSheet,
  Text,
  View,
} from "react-native";
import * as RNLocalize from "react-native-localize";

const styles = StyleSheet.create({
  safeArea: {
    backgroundColor: "white",
    flex: 1,
  },
  container: {
    padding: 16,
    alignItems: "flex-start",
  },
  block: {
    marginBottom: 16,
    alignItems: "flex-start",
  },
  name: {
    textDecorationLine: "underline",
    fontWeight: "500",
    marginBottom: 8,
    color: "black",
  },
  value: {
    textAlign: "left",
    color: "black",
  },
});

const Line = ({ name, value }: { name: string; value: unknown }) => (
  <View style={styles.block}>
    <Text style={styles.name}>{name}</Text>
    <Text style={styles.value}>{JSON.stringify(value, null, 2)}</Text>
  </View>
);
function LocalizeDemo() {
  return (
    <SafeAreaView style={styles.safeArea}>
      <ScrollView contentContainerStyle={styles.container}>
        <Line name="RNLocalize.getLocales()" value={RNLocalize.getLocales()} />

        <Line name="RNLocalize.getCurrencies()" value={RNLocalize.getCurrencies()} />

        <Line name="RNLocalize.getCountry()" value={RNLocalize.getCountry()} />

        <Line name="RNLocalize.getCalendar()" value={RNLocalize.getCalendar()} />

        <Line name="RNLocalize.getTimeZone()" value={RNLocalize.getTimeZone()} />

        <Line name="RNLocalize.uses24HourClock()" value={RNLocalize.uses24HourClock()} />

        <Line
          name="RNLocalize.findBestLanguageTag(['en-US', 'en', 'fr', 'zh'])"
          value={RNLocalize.findBestLanguageTag(["en-US", "en", "fr", 'zh'])}
        />
      </ScrollView>
    </SafeAreaView>
  );
}
export default LocalizeDemo;

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

Link

目前 HarmonyOS 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 HarmonyOS 工程 harmony

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

{
  ...
  "overrides": {
    "@rnoh/react-native-openharmony" : "./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

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-oh-tpl/react-native-localize": "file:../../node_modules/@react-native-oh-tpl/react-native-localize/harmony/rn_localize.har"
  }

点击右上角的 sync 按钮

或者在终端执行:

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

3.在 ArkTs 侧引入 RNLocalizePackage

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

  ...
  
+ import { RNLocalizePackage } from '@react-native-oh-tpl/react-native-localize/ts';

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

4.运行

点击右上角的 sync 按钮

或者在终端执行:

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。

请到三方库相应的 Releases 发布地址查看 Release 配套的版本信息:@react-native-oh-tpl/react-native-localize Releases

API

[!TIP] "Platform"列表示该属性在原三方库上支持的平台。

[!TIP] "HarmonyOS Support"列为 yes 表示 HarmonyOS 平台支持该属性;no 则表示不支持;partially 表示部分支持。使用方法跨平台一致,效果对标 iOS 或 Android 的效果。
