+
+## 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-picker Releases](https://github.com/react-native-oh-library/react-native-picker/releases)，并下载适用版本的 tgz 包。
+
+进入到工程目录并输入以下命令：
+
+> [!TIP] # 处替换为 tgz 包的路径
+
+<!-- tabs:start -->
+
+#### **npm**
+
+```bash
+npm install @react-native-oh-tpl/react-native-picker@file:#
+```
+
+#### **yarn**
+
+```bash
+yarn add @react-native-oh-tpl/react-native-picker@file:#
+```
+
+<!-- tabs:end -->
+
+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。
+
+```js
+import React from 'react';
+import { View, Button } from 'react-native';
+import Picker from 'react-native-picker';
+
+const MyPicker = () => {
+  let data = {
+    pickerData:
+      [{
+        a: [
+          {
+            a1: [1, 2, 3, 4]
+          },
+          {
+            a2: [5, 6, 7, 8]
+          },
+          {
+            a3: [9, 10, 11, 12]
+          }
+        ]
+      },
+      {
+        b: [
+          {
+            b1: [11, 22, 33, 44]
+          },
+          {
+            b2: [55, 66, 77, 88]
+          },
+          {
+            b3: [99, 1010, 1111, 1212]
+          }
+        ]
+      },
+      {
+        c: [
+          {
+            c1: ['a', 'b', 'c']
+          },
+          {
+            c2: ['aa', 'bb', 'cc']
+          },
+          {
+            c3: ['aaa', 'bbb', 'ccc']
+          }
+        ]
+      },],
+    isLoop: false,
+    selectedValue: ['b', 'b1', 22],
+    onPickerConfirm: data => {
+      console.log('onPickerConfirm:', data)
+    },
+    onPickerCancel: data => {
+      console.log('onPickerCancel:', data);
+    },
+    onPickerSelect: data => {
+      console.log('onPickerSelect:', data);
+    }
+  }
+  return (
+    <View>
+      <Button title='initPicker' onPress={() => Picker.init(data)} />
+      <Button title='showPicker' onPress={() => Picker.show()} />
+    </View>
+  );
+};
+
+export default MyPicker;
+```
+## 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
+
+```json
+{
+  ...
+  "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
+
+```json
+"dependencies": {
+    "@rnoh/react-native-openharmony": "file:../react_native_openharmony",
+    "@react-native-oh-tpl/react-native-picker": "file:../../node_modules/@react-native-oh-tpl/react-native-picker/harmony/picker.har"
+  }
+```
+
+点击右上角的 `sync` 按钮
+
+或者在终端执行：
+
+```bash
+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](/zh-cn/link-source-code.md)
+
+### 3.配置 CMakeLists 和引入 PickerPackage
+
+打开 `entry/src/main/cpp/CMakeLists.txt`，添加：
+
+```diff
+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-oh-tpl/react-native-picker/src/main/cpp" ./picker)
+# 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_native_picker)
+# RNOH_END: manual_package_linking_2
+```
+
+打开 `entry/src/main/cpp/PackageProvider.cpp`，添加：
+
+```diff
+#include "RNOH/PackageProvider.h"
+#include "generated/RNOHGeneratedPackage.h"
+#include "SamplePackage.h"
++ #include "PickerPackage.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<PickerPackage>(ctx),
+    };
+}
+```
+
+### 4.在 ArkTs 侧引入 PickerViewPackage
+
+打开 `entry/src/main/ets/RNPackagesFactory.ts`，添加：
+
+```diff
+  ...
++ import { PickerViewPackage } from "@react-native-oh-tpl/react-native-picker"
+
+export function createRNPackages(ctx: RNPackageContext): RNPackage[] {
+  return [
++  new PickerViewPackage(ctx),
+  ];
+}
+```
+
+### 5.运行
+
+点击右上角的 `sync` 按钮
+
+或者在终端执行：
+
+```bash
+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-picker Releases](https://github.com/react-native-oh-library/react-native-picker/releases)

+## 遗留问题
+
+- [ ] 当前picker是使用的TextPicker实现，TextPicker并未提供每列设置宽度的方法，因此暂不能支持wheelFlex。[issue#6](https://github.com/react-native-oh-library/react-native-picker/issues/6)
+- [ ] 当前TextPicker的字体设置目前只支持大小和字体粗细，不支持pickerFontFamily。[issue#7](https://github.com/react-native-oh-library/react-native-picker/issues/7)
