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 🙏

@capacitor-ohos/keyboard

v8.0.1

Published

The Keyboard API provides keyboard display and visibility control, along with event tracking when the keyboard shows and hides.

Readme

@capacitor/keyboard

zh-CN en

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

简介

@capacitor/keyboard是capacitor生态系统中的核心插件,提供完善的键盘控制API,支持对设备键盘进行显示、隐藏操作,同时可监听键盘弹出、收起相关事件,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,本文档只说明在OpenHarmony系统中的使用。

API 允许对设备键盘进行显示与隐藏控制,同时支持监听键盘弹出和收起时的事件,满足应用中键盘交互的各类场景需求。

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 i @capacitor/keyboard

# 同步插件
hionic sync

hionic CLI安装:

hionic plugin add @capacitor/keyboard

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,通过 target 字段找到 entry 模块中 capacitor.plugins.json 文件,并根据 param 标签添加配置如下:

[
  {
    "pkg": "@capacitor/keyboard",
    "classpath": "Keyboard"
  }
]

2. 修改 CMake 配置

根据 plugin.xmlCMakeLists 项,通过 modules-name 字段找到模块 capacitor,路径为 target 字段的 CMakeLists.txt 文件,并添加 add_subdirectorytarget_link_libraries 如下:

#START_ADD_SUBDIRECTORY
// ...
add_subdirectory(Keyboard)
// ...
#END_ADD_SUBDIRECTORY

// ...

target_link_libraries(capacitor PUBLIC
  "-Wl,--whole-archive"
  // ...
  Keyboard
  // ...
  "-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,并根据 modules-name 字段和 target-dir 字段找到文件复制的具体模块和目录:

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

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

4. 添加 ArkTS 配置

capacitor模块的build-profile.json5文件中,buildOption/arkOptions/runtimeOnly/sources配置项数组中加入步骤 3 中拷贝的 ets 文件路径:

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

卸载

# 卸载 keyboard 插件
hionic plugin remove @capacitor/keyboard

约束与限制

兼容性

在以下版本中已测试通过:

  • capacitor: 8.0.0-ohos-8.0.0; SDK: 5.0.5(17); IDE: DevEco Studio: 6.0.0; ROM: 5.1.0.150;

权限要求

OpenHarmony系统中,键盘控制相关操作无需额外申请权限,插件可直接调用相关API实现功能。

使用示例

示例1:显示键盘

import { Keyboard } from '@capacitor/keyboard';

const handleShowKeyboard = async () => {
  try {
    // 使用capacitor Keyboard插件显示键盘
    await Keyboard.show();

    apiButtonSectionRef.value?.updateButtonResult('show-keyboard', {
      message: '键盘显示命令已发送(仅Android支持)',
      status: 'success'
    });
  } catch (error) {
    const errorMsg = error instanceof Error ? error.message : String(error);
    apiButtonSectionRef.value?.updateButtonResult('show-keyboard', {
      message: `显示键盘失败: ${errorMsg}`,
      status: 'error'
    });
  }
};

示例2:隐藏键盘

import { Keyboard } from '@capacitor/keyboard';

const handleHideKeyboard = async () => {
  try {
    // 使用capacitor Keyboard插件隐藏键盘
    await Keyboard.hide();

    apiButtonSectionRef.value?.updateButtonResult('hide-keyboard', {
      message: '键盘隐藏命令已发送',
      status: 'success'
    });
  } catch (error) {
    const errorMsg = error instanceof Error ? error.message : String(error);
    apiButtonSectionRef.value?.updateButtonResult('hide-keyboard', {
      message: `隐藏键盘失败: ${errorMsg}`,
      status: 'error'
    });
  }
};

示例3:添加键盘监听事件

import { Keyboard } from '@capacitor/keyboard';

const handleAddListeners = async () => {
  try {
    // 使用capacitor Keyboard插件添加键盘事件监听器
    Keyboard.addListener('keyboardWillShow', (info) => {
      console.log('键盘即将显示:', info);
    });

    Keyboard.addListener('keyboardDidShow', (info) => {
      console.log('键盘已显示:', info);
    });

    Keyboard.addListener('keyboardWillHide', () => {
      console.log('键盘即将隐藏');
    });

    Keyboard.addListener('keyboardDidHide', () => {
      console.log('键盘已隐藏');
    });

    apiButtonSectionRef.value?.updateButtonResult('add-listeners', {
      message: '键盘事件监听器已添加',
      status: 'success'
    });
  } catch (error) {
    const errorMsg = error instanceof Error ? error.message : String(error);
    apiButtonSectionRef.value?.updateButtonResult('add-listeners', {
      message: `添加键盘事件监听器失败: ${errorMsg}`,
      status: 'error'
    });
  }
};

示例4:移除所有键盘监听事件

import { Keyboard } from '@capacitor/keyboard';

const handleRemoveAllListeners = async () => {
  try {
    // 使用capacitor Keyboard插件移除所有键盘事件监听器
    await Keyboard.removeAllListeners();

    apiButtonSectionRef.value?.updateButtonResult('remove-listeners', {
      message: '所有键盘事件监听器已移除',
      status: 'success'
    });
  } catch (error) {
    const errorMsg = error instanceof Error ? error.message : String(error);
    apiButtonSectionRef.value?.updateButtonResult('remove-listeners', {
      message: `移除键盘事件监听器失败: ${errorMsg}`,
      status: 'error'
    });
  }
};

使用说明

Keyboard是插件导出对象,可直接导入使用,导入后即可调用插件提供的所有方法,调用便捷高效,所有API均基于Promise实现,支持异步调用。

| 方法名 | 返回类型 | 描述 | 备注 | |----------------------------------------------------------------------------------------|--------------------------------------------------------------|---------------|--------------| | show() | Promise<void> | 显示键盘 | 仅Android支持 | | hide() | Promise<void> | 隐藏键盘 | 无 | | addListener(eventName: 'keyboardWillShow', listenerFunc: (info: KeyboardInfo) => void) | Promise<PluginListenerHandle> | 监听键盘即将弹出的事件 | 从API20之后开始支持 | | addListener(eventName: 'keyboardDidShow', listenerFunc: (info: KeyboardInfo) => void) | Promise<PluginListenerHandle> | 监听键盘弹出的事件 | 从API18之后开始支持 | | addListener(eventName: 'keyboardWillHide', listenerFunc: (info: KeyboardInfo) => void) | Promise<PluginListenerHandle> | 监听键盘即将隐藏的事件 | 从API20之后开始支持 | | addListener(eventName: 'keyboardDidHide', listenerFunc: (info: KeyboardInfo) => void) | Promise<PluginListenerHandle> | 监听键盘隐藏的事件 | 从API18之后开始支持 | | removeAllListeners() | Promise<void> | 移除该插件的所有原生监听器 | 无 |

数据结构
