模板版本:v0.2.2
@ohmi/react-native-picker
安装与使用
进入到工程目录并输入以下命令:
npm
npm install @ohmi/react-native-picker
yarn
yarn add @ohmi/react-native-picker
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。
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
{
...
"overrides": {
"@rnoh/react-native-openharmony" : "./react_native_openharmony"
}
}
2.引入原生端代码
目前有两种方法:
- 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);
- 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-picker": "file:../../node_modules/@ohmi/react-native-picker/harmony/picker.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 PickerPackage
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-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:
#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:
...
+ import { PickerViewPackage } from "@ohmi/react-native-picker/ts"
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:
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。

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
- 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
