介绍

服务卡片的布局和使用，其中卡片内容显示使用了一次开发，多端部署的能力实现多设备自适应。
用到了卡片扩展模块接口，[@ohos.app.form.FormExtensionAbility] 。

卡片信息和状态等相关类型和枚举接口，[@ohos.app.form.formInfo]。

卡片数据绑定的能力接口[@ohos.app.form.formBindingData]。

使用说明

长按示例应用，等待出现服务卡片字样，点击后可左右滑动选择需要的卡片尺寸，添加到屏幕。

具体实现

1、在module.json5文件添加拓展能力，类型为卡片，并设置卡片入口srcEntrance和卡片元数据metadata。[源码参考] 。

例如："metadata": [ { "name": "ohos.extension.form", "resource": "$profile:form_config" }。
2、初始化卡片：通过实现@ohos.app.form.FormExtensionAbility卡片操作类，在卡片对象首次被创建时，初始化卡片绑定数据为空，并将卡片状态设置为就绪状态READY。例如：onCreate(){ formBindingData.createFormBindingData({}) onAcquireFormState(want) { return formInfo.FormState.READY }。
3、配置卡片：用js编写相应的卡片，将卡片配置到resources/base/profile/form_config, [源码参考]

{"forms": [{"name": "complex","description": "This is a service widget.","src": "./js/complex/pages/index/index","window": {"designWidth": 720,"autoDesignWidth": true},"colorMode": "auto","isDefault": true,"updateEnabled": true,"scheduledUpdateTime": "10:30","updateDuration": 1,"defaultDimension": "2*2","supportDimensions": ["2*2","4*4"]},{"name": "test","description": "This is a service widget.","src": "./js/test/pages/index/index","window": {"designWidth": 720,"autoDesignWidth": true},"colorMode": "auto","isDefault": false,"updateEnabled": true,"scheduledUpdateTime": "10:30","updateDuration": 1,"defaultDimension": "2*2","supportDimensions": ["2*2"]},{"name": "immersive","description": "This is a service widget.","src": "./js/immersive/pages/index/index","window": {"designWidth": 720,"autoDesignWidth": true},"colorMode": "auto","isDefault": false,"updateEnabled": true,"scheduledUpdateTime": "10:30","updateDuration": 1,"defaultDimension": "2*2","supportDimensions": ["2*2"]},{"name": "grid","description": "This is a service widget.","src": "./js/grid/pages/index/index","window": {"designWidth": 720,"autoDesignWidth": true},"colorMode": "auto","isDefault": false,"updateEnabled": true,"scheduledUpdateTime": "10:30","updateDuration": 1,"defaultDimension": "2*2","supportDimensions": ["2*2"]},{"name": "imgText","description": "This is a service widget.","src": "./js/imgText/pages/index/index","window": {"designWidth": 720,"autoDesignWidth": true},"colorMode": "auto","isDefault": false,"updateEnabled": true,"scheduledUpdateTime": "10:30","updateDuration": 1,"defaultDimension": "2*2","supportDimensions": ["2*2","2*4"]}]}

最后呢，很多开发朋友不知道需要学习那些鸿蒙技术？鸿蒙开发岗位需要掌握那些核心技术点？为此鸿蒙的开发学习必须要系统性的进行。

而网上有关鸿蒙的开发资料非常的少，假如你想学好鸿蒙的应用开发与系统底层开发。你可以参考这份资料，少走很多弯路，节省没必要的麻烦。由两位前阿里高级研发工程师联合打造的《鸿蒙NEXT星河版OpenHarmony开发文档》里面内容包含了（ArkTS、ArkUI开发组件、Stage模型、多端部署、分布式应用开发、音频、视频、WebGL、OpenHarmony多媒体技术、Napi组件、OpenHarmony内核、Harmony南向开发、鸿蒙项目实战等等）鸿蒙（Harmony NEXT）技术知识点

如果你是一名Android、Java、前端等等开发人员，想要转入鸿蒙方向发展。可以直接领取这份资料辅助你的学习。下面是鸿蒙开发的学习路线图。
