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 🙏

@ionic-native/keyboard

zh-CN en

本项目基于@ionic-native/[email protected]开发。

简介

@ionic-native/keyboard是OpenHarmony Cordova生态系统中的核心插件,提供键盘的显示与可见性控制功能,同时支持监听键盘弹出和收起时的事件,为跨平台应用开发提供设备差异化适配能力。兼容Android、iOS 和OpenHarmony平台,为跨平台应用开发提供统一的键盘控制能力。本文档主要说明在OpenHarmony系统中的应用。

@ionic-native/keyboardAPI提供键盘的显示与隐藏功能,同时支持监听键盘事件。

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 @ionic-native/keyboard

# 同步插件
hionic sync

hionic CLI安装:

hionic plugin add @ionic-native/keyboard

手动引入安装

1.添加插件配置

根据 plugin.xmlconfig-json 项,找到 entry 模块中 config.xml 文件,并根据 param 标签添加配置

<feature name="Keyboard">
  <param name="harmony-package" value="Keyboard" />
  <param name="onload" value="true" />
</feature>

2.修改CMake配置

根据 plugin.xmlCMakeLists 项,找到 cordova 模块,路径为 target 字段的文件 CMakeLists.txt,添加 add_library

add_library(cordova SHARED
  // ...
  Keyboard/CDVIonicKeyboard.cpp
  // ...
)

3.复制源码文件

根据 plugin.xmlsource-file 项,将 src 字段的路径代码复制到 cordova 模块中 target-dir 字段的目录中:

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

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

4.添加ArkTS配置

cordova 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": {
      "sources": [
        // ...
        "./src/main/ets/components/Keyboard/KeyboardAction.ets"
        // ...
      ]
    }
  }
}

卸载

# hionic CLI 卸载
hionic plugin remove @ionic-native/keyboard
