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-amap-geolocation 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-amap-geolocation

yarn

yarn add @react-native-oh-tpl/react-native-amap-geolocation

下面的代码展示了这个库的基本使用场景:

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.json 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-amap-geolocation": "file:../../node_modules/@react-native-oh-tpl/react-native-amap-geolocation/harmony/amap_geolocation.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 AmapGeolocationPackage

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

...
+  import {AMapGeolocationPackage} from '@react-native-oh-tpl/react-native-amap-geolocation/ts';

export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
  return [
    new SamplePackage(ctx),
+   new AMapGeolocationPackage(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-amap-geolocation Releases

权限要求

在 entry 目录下的module.json5中添加权限

打开 entry/src/main/module.json5,添加:

...
"requestPermissions": [
  {
    "name": "ohos.permission.LOCATION",
    "reason": "$string:Access_Location",
    "usedScene": {
      "when":"inuse"
    }
  },
  {
    "name": "ohos.permission.APPROXIMATELY_LOCATION",
    "reason": "$string:Access_AppRoximatelyLocation",
    "usedScene": {
      "when":"inuse"
    }
  },
  {
    "name": "ohos.permission.INTERNET",
  }
]

在 entry 目录下添加位置权限的原因

打开 entry/src/main/resources/base/element/string.json,添加:

...
{
  "string": [
    {
      "name": "Access_Location",
      "value": "access Location"
    },
    {
      "name": "Access_AppRoximatelyLocation",
      "value": "access AppRoximatelyLocation"
    }
  ]
}

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。
