# 常用组件说明 组件是构建页面的核心,每个组件通过对数据和方法的简单封装,实现独立的可视、可交互功能单元。组件之间相互独立,随取随用,也可以在需求相同的地方重复使用。 声明式开发范式目前可供选择的组件如下表所示。 | 组件类型 | 主要组件 | | ---------------------------- | ---------------------------------------------------------- | | [基础组件](../reference/arkui-ts/ts-basic-components-blank.md) | Blank、Button、Checkbox、CheckboxGroup、DataPanel、DatePicker、Divider、Gauge、Image、ImageAnimator、LoadingProgress、Marquee、Navigation、PatternLock、PluginComponent、Progress、QRCode、Radio、Rating、RemoteWindow、RichText、ScrollBar、Search、Select、Slider、Span、Stepper、StepperItem、Text、TextArea、TextClock、TextInput、TextPicker、TextTimer、TimePicker、Toggle、Web、XComponent | | [容器组件](../reference/arkui-ts/ts-container-ability-component.md) | AbilityComponent、AlphabetIndexer、Badge、Column、ColumnSplit、Counter、Flex、FlowItem、GridContainer、GridCol、GridRow、Grid、GridItem、List、ListItem、ListItemGroup、Navigator、Panel、Refresh、RelativeContainer、Row、RowSplit、Scroll、SideBarContainer、Stack、Swiper、Tabs、TabContent、WaterFlow | | [媒体组件](../reference/arkui-ts/ts-media-components-video.md) | Video | | [绘制组件](../reference/arkui-ts/ts-drawing-components-circle.md) | Circle、Ellipse、Line、Polyline、Polygon、Path、Rect、Shape | | [画布组件](../reference/arkui-ts/ts-components-canvas-canvas.md) | Canvas | ## 相关实例 基于ArkTS的常用组件开发,有以下相关实例可供参考: - [`ComponentCollection`:组件集合(ArkTS)(API9)](https://gitee.com/openharmony/applications_app_samples/tree/master/ETSUI/ComponentCollection) - [`OrangeShopping`:购物示例应用(ArkTS)(API9)](https://gitee.com/openharmony/applications_app_samples/tree/master/ETSUI/OrangeShopping) - [`Canvas`:画布组件(ArkTS)(API8)](https://gitee.com/openharmony/applications_app_samples/tree/master/ETSUI/Canvas) - [`Clock`:简单时钟(ArkTS)(API9)](https://gitee.com/openharmony/applications_app_samples/tree/master/Preset/Clock) - [`PatternLock`:图案密码锁组件(ArkTS)(API9)](https://gitee.com/openharmony/applications_app_samples/tree/master/ETSUI/PatternLock) - [`Search`:Search组件(ArkTS)(API9)](https://gitee.com/openharmony/applications_app_samples/tree/master/ETSUI/Search) - [`QRCode`:二维码(ArkTS)(API9)(Full SDK)](https://gitee.com/openharmony/applications_app_samples/tree/master/ETSUI/QRCode) - [`Gallery`:组件集合(ArkTS)(API8)](https://gitee.com/openharmony/applications_app_samples/tree/master/ETSUI/Gallery) - [List组件的使用之商品列表(ArkTS)(API9)](https://gitee.com/openharmony/codelabs/tree/master/ETSUI/List_HDC) - [List组件的使用之设置项(ArkTS)(API9)](https://gitee.com/openharmony/codelabs/tree/master/ETSUI/List_HDC)
