react-native-charts-wrapper

首先需要使用 DevEco Studio 打开项目里的 HarmonyOS 工程 harmony

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

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

3.2. 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-charts-wrapper": "file:../../node_modules/@react-native-ohos/react-native-charts-wrapper/harmony/charts_wrapper.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

3.3. 配置 CMakeLists 和引入 ChartsWrapperPackage

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 "${CMAKE_CURRENT_SOURCE_DIR}/../../../oh_modules")
+ set(RNOH_GENERATED_DIR "${CMAKE_CURRENT_SOURCE_DIR}/generated")
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-charts-wrapper/src/main/cpp" ./charts-wrapper)

# 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_charts_wrapper)
# RNOH_END: manual_package_linking_2

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

3.4. 在 ArkTs 侧引入 BarCharts、LineCharts、HorizontalBarCharts 、BubbleCharts、PieCharts、RadarCharts、ScatterCharts、CandleStickCharts、CombinedCharts 组件

找到 function buildCustomComponent()，一般位于 entry/src/main/ets/pages/index.ets 或 entry/src/main/ets/rn/LoadBundle.ets，添加：

  ...
+ import {
+  BarCharts,
+  LineCharts,
+  HorizontalBarCharts,
+  BubbleCharts,
+  PieCharts,
+  RadarCharts,
+  ScatterCharts,
+  CandleStickCharts,
+  CombinedCharts
+ } from "@react-native-ohos/react-native-charts-wrapper"

@Builder
export function buildCustomRNComponent(ctx: ComponentBuilderContext) {
  ...
+    if (ctx.componentName === BarCharts.NAME) {
+      BarCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === LineCharts.NAME) {
+      LineCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === HorizontalBarCharts.NAME) {
+      HorizontalBarCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === BubbleCharts.NAME) {
+      BubbleCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === PieCharts.NAME) {
+      PieCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === RadarCharts.NAME) {
+      RadarCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === ScatterCharts.NAME) {
+      ScatterCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === CandleStickCharts.NAME) {
+      CandleStickCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
+    if (ctx.componentName === CombinedCharts.NAME) {
+      CombinedCharts({
+        ctx: ctx.rnComponentContext,
+        tag: ctx.tag
+      })
+    }
 ...
}

在entry/src/main/ets/pages/index.ets 或 entry/src/main/ets/rn/LoadBundle.ets 找到常量 arkTsComponentNames 在其数组里添加组件名

const arkTsComponentNames: Array<string> = [
  SampleView.NAME,
  GeneratedSampleView.NAME,
  PropsDisplayer.NAME,
+ BarCharts.NAME,
+ LineCharts.NAME,
+ HorizontalBarCharts.NAME,
+ BubbleCharts.NAME,
+ PieCharts.NAME,
+ RadarCharts.NAME,
+ ScatterCharts.NAME,
+ CandleStickCharts.NAME,
+ CombinedCharts.NAME
  ];

3.5. 在 ArkTs 侧引入 ChartsWrapperPackage

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

  ...
+ import {ChartsWrapperPackage} from '@react-native-ohos/react-native-charts-wrapper/ts';

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