介绍

该项目基于react-native-amap-geolocation开发。

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：@ohmi/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 @ohmi/react-native-amap-geolocation

yarn

yarn add @ohmi/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",
    "@ohmi/react-native-amap-geolocation": "file:../../node_modules/@ohmi/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 '@ohmi/react-native-amap-geolocation/ts';

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

4.配置 CMakeLists 和引入 RNAmapGeolocationPackage

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

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-amap-geolocation/src/main/cpp" ./amap_geolocation)
# 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_amap_geolocation)
# RNOH_END: manual_package_linking_2

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

#include "RNOH/PackageProvider.h"
#include "generated/RNOHGeneratedPackage.h"
#include "SamplePackage.h"
+ #include "RNAmapGeolocationPackage.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<RNAmapGeolocationPackage>(ctx),
    };
}

5.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

本文档内容基于以下版本验证通过：

RNOH：0.72.50; SDK：5.0.2.126 ; IDE：DevEco Studio 5.0.7.210; ROM：5.0.0.135;

高德 APP KEY

为了使用高德 SDK，你需要准备高德 App Key，获取方法参考高德地图 SDK 官方文档：

高德地图 SDK

鸿蒙端获取应用的appId参考代码如下

import { bundleManager } from '@kit.AbilityKit';

  getAppId(){
    let flag = bundleManager.BundleFlag.GET_BUNDLE_INFO_WITH_SIGNATURE_INFO;
    let bundleInfo = bundleManager.getBundleInfoForSelfSync(flag)
    let appId = bundleInfo.signatureInfo.appId
    console.log('harmony_appId', JSON.stringify(appId))
  }

aboutToAppear(){
    this.getAppId()
}
// 最终获取的appId格式类似于：com.amap.demo_BGtGgVB3ASqU7ar1nHkwX4s0nIexDbEwqNrVoatUDs17GrClWC7V2/zhoYh6tFQHAd5DASWVTEAgvZfzrEGljjs=

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"
    }
  ]
}
