!TIP(https://gitee.com/kunyuan-hongke/react-native-orientation)

1. 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-orientation 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-orientation

yarn

yarn add @ohmi/react-native-orientation

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 Orientation from 'react-native-orientation';
import {Alert, StyleSheet, Text, TouchableOpacity, View} from 'react-native';
import {useEffect, useState} from 'react';

export default function OrientationDemo() {
  const [orientation, setOrientation] = useState<string>();
  const [SpecificOrientation, setSpecificOrientation] = useState<string>();
  const updateOrientation = (orientation: string) => {
    console.info('orientation', orientation);
    setOrientation(orientation);
  };
  const UpdateSpecificOrientation = (SpecificOrientation: string) => {
    console.info('SpecificOrientation', SpecificOrientation);
    setSpecificOrientation(SpecificOrientation);
  };
  useEffect(() => {
    // 开启方向变化的监听
    Orientation.addOrientationListener(updateOrientation);
    Orientation.addSpecificOrientationListener(UpdateSpecificOrientation);
    return () => {
     // 移除方向变化的监听
      Orientation.removeOrientationListener(updateOrientation);
      Orientation.removeSpecificOrientationListener(UpdateSpecificOrientation);
    };
  }, []);
  // 获取方向
  const getOrientationInt = () => {
    Orientation.getOrientation((err: string, orientation: string) => {
      if (orientation) {
        Alert.alert(`当前屏幕方向为${orientation}`);
      } else {
        Alert.alert(err);
      }
    });
  };
  // 获取具体方向
  const getSpecificOrientationInt = () => {
    Orientation.getSpecificOrientation((err: string, orientation: string) => {
      if (orientation) {
        Alert.alert(`当前屏幕方向为${orientation}`);
      } else {
        Alert.alert(err);
      }
    });
  };
  // 锁定方向为纵向(竖屏)
  const setLockToPortrait = () => {
    Orientation.lockToPortrait();
  };
  // 锁定方向为横向(横屏)
  const setLockToLandscape = () => {
    Orientation.lockToLandscape();
  };
  // 锁定方向为横向,并且是向左旋转的方向
  const setLockToLandscapeLeft = () => {
    Orientation.lockToLandscapeLeft();
  };
  // 锁定方向为横向,并且是向右旋转的方向
  const setLockToLandscapeRight = () => {
    Orientation.lockToLandscapeRight();
  };
  // 解除方向的锁定,允许自由旋转
  const unlockAllOrientations = () => {
    Orientation.unlockAllOrientations();
  };
  return (
    <View style={styles.container}>
      <Text>{`Current Orientation: ${orientation}`}</Text>
      <Text>{`Current SpecificOrientation: ${SpecificOrientation}`}</Text>
      <TouchableOpacity onPress={getOrientationInt} style={styles.button}>
        <Text style={styles.instructions}>获取当前屏幕的方向</Text>
      </TouchableOpacity>
      <TouchableOpacity
        onPress={getSpecificOrientationInt}
        style={styles.button}>
        <Text style={styles.instructions}>获取当前屏幕具体的方向</Text>
      </TouchableOpacity>
      <TouchableOpacity onPress={setLockToPortrait} style={styles.button}>
        <Text style={styles.instructions}>锁定当前屏幕为竖屏</Text>
      </TouchableOpacity>
      <TouchableOpacity onPress={setLockToLandscape} style={styles.button}>
        <Text style={styles.instructions}>锁定当前屏幕为横屏</Text>
      </TouchableOpacity>
      <TouchableOpacity onPress={setLockToLandscapeLeft} style={styles.button}>
        <Text style={styles.instructions}>锁定当前屏幕为横屏,左旋转</Text>
      </TouchableOpacity>
      <TouchableOpacity onPress={setLockToLandscapeRight} style={styles.button}>
        <Text style={styles.instructions}>锁定当前屏幕为横屏,右旋转</Text>
      </TouchableOpacity>
      <TouchableOpacity onPress={unlockAllOrientations} style={styles.button}>
        <Text style={styles.instructions}>解锁当前屏幕旋转锁定</Text>
      </TouchableOpacity>
    </View>
  );
}

const styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'flex-start',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
    marginTop: 20,
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#eeeeee',
    marginBottom: 0,
  },
  buttonContainer: {
    flex: 0,
    flexDirection: 'row',
    justifyContent: 'space-around',
  },
  button: {
    padding: 5,
    margin: 5,
    borderWidth: 1,
    borderColor: 'white',
    borderRadius: 3,
    backgroundColor: 'grey',
  },
});

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 文档

2. 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

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

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

2.2 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

!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-orientation": "file:../../node_modules/@ohmi/react-native-orientation/harmony/rn_orientation.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

打开终端,执行:

cd entry
ohpm install --no-link

2.3 在 ArkTs 侧引入 RNOrientationPackage

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

  ...
+ import { RNOrientationPackage } from '@ohmi/react-native-orientation/ts';

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

2.4 配置 CMakeLists 和引入 SQLitePluginPackage

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("${OH_MODULES}/@ohmi/react-native-orientation/src/main/cpp" ./rn_orientation)
# 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_oritentation)
# 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 "RNOrientationPackage.h"

using namespace rnoh;

std::vector<std::shared_ptr<Package>> PackageProvider::getPackages(Package::Context ctx) {
    return {
        std::make_shared<RNOHGeneratedPackage>(ctx),
+       std::make_shared<RNOrientationPackage>(ctx),
    };
}
### 2.4 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。

3. 约束与限制

3.1 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-library/react-native-orientation Releases

4. API

!TIP "Platform"列表示该属性在原三方库上支持的平台。

!TIP "HarmonyOS Support"列为 yes 表示 HarmonyOS 平台支持该属性;no 则表示不支持;partially 表示部分支持。使用方法跨平台一致,效果对标 iOS 或 Android 的效果。

Events

!TIP "Platform"列表示该属性在原三方库上支持的平台。

5. 遗留问题

  • 第三方库的获取app初始化时设备屏幕方向的api在鸿蒙手机里没有。
