Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@capacitor/screen-orientation

zh-CN en

本项目基于 @capacitor/[email protected] 开发。

简介

提供屏幕方向 API 及相关功能,支持获取当前方向、锁定/解锁方向和监听方向变化。本插件是 capacitor 生态系统中的核心插件,为跨平台应用开发提供设备差异化适配能力,兼容 capacitor 的 Android、iOS 等主流移动平台及浏览器环境中使用,本文档仅说明在 OpenHarmony 系统中的使用情况。

支持平台

  • OpenHarmony:5.0+

下载安装

通过命令行或手动引入即可快速安装插件,支持从npm仓库获取。

命令行安装(推荐)

安装hionic CLI:

npm install -g hionic

以下两种方式中任选其一即可,无需重复操作:

npm安装:

# 安装插件
npm install @capacitor/screen-orientation

# 同步插件
hionic sync

hionic CLI安装:

hionic plugin add @capacitor/screen-orientation

手动引入安装

根据插件源码中 plugin.xml 配置在项目中引入插件:

1. 添加插件配置

根据 plugin.xmlconfig-json 项,找到 entry 模块中 capacitor.plugins.json 文件,并根据 param 标签添加配置如下:

{
  "pkg": "@capacitor/screen-orientation",
  "classpath": "ScreenOrientation"
}

2. 修改 CMake 配置

根据 plugin.xmlCMakeLists 项,找到 capacitor 模块,路径为 target 字段的 CMakeLists.txt 文件,并添加 add_subdirectorytarget_link_libraries 如下:

// ...
add_subdirectory(ScreenOrientation)
// ...

// ...
target_link_libraries(capacitor PUBLIC
  "-Wl,--whole-archive"
  // ...
  ScreenOrientation
  // ...
  "-Wl,--no-whole-archive"
);

3. 复制源码文件

根据 plugin.xmlsource-file 项,根据 src 字段找到需要复制的文件,并复制到对应的目录:

将源码中 src/main/cpp/ScreenOrientation 目录下 ScreenOrientation.h、ScreenOrientation.cpp、CMakeLists.txt 文件引入到 capacitor 模块中 src/main/cpp/ScreenOrientation 目录下。

将源码中 src/main/ets/components/ScreenOrientation 目录下 ScreenOrientation.ets 文件引入到 capacitor 模块中 src/main/ets/components/ScreenOrientation 目录下。

capacitor 模块下 build-profile.json5 文件中,buildOption/arkOptions/runtimeOnly/sources 配置项数组中加入拷贝的 ets 文件路径:

"buildOption": {
  "arkOptions": {
    "runtimeOnly": {
      "sources": [
        // ...
        "./src/main/ets/components/ScreenOrientation/ScreenOrientation.ets"
        // ...
      ]
    }
  }
}

卸载

# 卸载 screen-orientation 插件
hionic plugin remove @capacitor/screen-orientation

约束与限制

兼容性

在以下版本中已测试通过:

  1. SDK: 5.0.5(17); IDE: DevEco Studio: 6.0.0; ROM: 5.1.0.150;

权限要求

不需要额外权限。

使用示例

基础示例:获取屏幕方向、锁定方向、解锁方向并监听方向变化

import { ScreenOrientation } from '@capacitor/screen-orientation';

// 获取当前屏幕方向
const getOrientation = async () => {
  const result = await ScreenOrientation.orientation();
  console.log('Current orientation:', result.type);
};

// 锁定屏幕方向为横屏
const lockLandscape = async () => {
  await ScreenOrientation.lock({
    orientation: 'landscape'
  });
};

// 锁定屏幕方向为竖屏
const lockPortrait = async () => {
  await ScreenOrientation.lock({
    orientation: 'portrait'
  });
};

// 解锁屏幕方向
const unlockOrientation = async () => {
  await ScreenOrientation.unlock();
};

// 监听屏幕方向变化
const listenOrientationChanges = async () => {
  const listener = await ScreenOrientation.addListener(
    'screenOrientationChange',
    (orientation) => {
      console.log('Orientation changed:', orientation.type);
    }
  );

  // 稍后移除监听器
  // listener.remove();
};

// 移除所有监听器
const removeAllListeners = async () => {
  await ScreenOrientation.removeAllListeners();
};
