react-native-bars

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" : "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）

打开 entry/oh-package.json5，添加以下依赖

"dependencies": {
    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
    "@react-native-ohos/react-native-bars": "file:../../node_modules/@react-native-ohos/react-native-bars/harmony/bars.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

3.配置 CMakeLists 和引入 BarsPackage

若使用的是 <= 2.4.3-0.0.3 版本，请跳过本章。

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}/@react-native-ohos/react-native-bars/src/main/cpp" ./bars)
# 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_bars)
# RNOH_END: manual_package_linking_2

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

#include "RNOH/PackageProvider.h"
+ #include "BarsPackage.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx)
{
     return {
+    std::make_shared<BarsPackage>(ctx)
    };
}

4.在 ArkTs 侧引入 RNBarsPackage

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

  ...
+ import {RNBarsPackage} from '@react-native-ohos/react-native-bars/ts';

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