# 属性字符串（StyledString/MutableStyledString）

属性字符串StyledString/MutableStyledString（MutableStyledString继承于StyledString，以下统一简称StyledString）是功能强大的标记对象，可用于字符或段落级别设置文本样式。通过将StyledString附加到文本组件， 可以通过多种方式更改文本，包括修改字号、添加字体颜色、使文本可点击以及自定义方式绘制文本等。具体用法可参考[属性字符串](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#属性字符串)。

属性字符串提供多种类型样式对象，涵盖各种常见的文本样式格式。也可以自行创建CustomSpan, 以应用自定义样式。 

## 创建并应用StyledString和MutableStyledString

  可以通过TextController提供的setStyledString(StyledString)方法将属性字符串附加到文本组件，并推荐在onPageShow中触发绑定，在aboutToAppear中调用setStyledString无法实现页面初始即可见属性字符串文本内容，因为aboutToAppear运行时组件还没有完成创建并成功挂载节点树。

  ```ts
  @Entry
  @Component
  struct styled_string_demo1 {
    styledString1: StyledString = new StyledString("运动45分钟");
    mutableStyledString1: MutableStyledString = new MutableStyledString("运动35分钟");
    controller1: TextController = new TextController();
    controller2: TextController = new TextController();

    async onPageShow() {
      this.controller1.setStyledString(this.styledString1)
      this.controller2.setStyledString(this.mutableStyledString1)
    }

    build() {
      Column() {
        // 显示属性字符串
        Text(undefined, { controller: this.controller1 })
        Text(undefined, { controller: this.controller2 })
      }
      .width('100%')
    }
  }
  ```

## 设置文本样式

属性字符串目前提供了[TextStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#textstyle)、[TextShadowStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#textshadowstyle)、[DecorationStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#decorationstyle)、[BaselineOffsetStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#baselineoffsetstyle)、[LineHeightStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#lineheightstyle)、[LetterSpacingStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#letterspacingstyle)各种Style对象来实现设置文本的各类样式。

    mutableStyledString: MutableStyledString = new MutableStyledString("运动35分钟 目标达成", [
      {
        start: 2,
        length: 2,
        styledKey: StyledStringKey.FONT,
        styledValue: this.textStyleAttrs
      },

      {
        start: 0,
        length: 3,
        styledKey: StyledStringKey.BASELINE_OFFSET,
        styledValue: new BaselineOffsetStyle(LengthMetrics.px(20))
      }
    ]);
    controller: TextController = new TextController();

    async onPageShow() {
      this.controller.setStyledString(this.mutableStyledString)
    }

    build() {
      Column() {
        // 显示属性字符串
        Text(undefined, { controller: this.controller })
      }
      .width('100%')
    }
  }
  ```
  ![StyledString_Baseline](figures/styled_string_baselineoffset.png)

- 创建及应用文本行高对象（LineHeightStyle）

  ```ts
  import { LengthMetrics, LengthUnit } from '@kit.ArkUI'
  // xxx.ets
  @Entry
  @Component
  struct styled_string_demo6 {
    mutableStyledString: MutableStyledString = new MutableStyledString("运动35分钟\n顶顶顶\n得到", [
      {

        length: 3,
        styledKey: StyledStringKey.LINE_HEIGHT,
        styledValue: new LineHeightStyle(LengthMetrics.vp(50))
      }
    ]);
    controller: TextController = new TextController();

    async onPageShow() {
      this.controller.setStyledString(this.mutableStyledString)
    }

    build() {
      Column() {
        // 显示属性字符串
        Text(undefined, { controller: this.controller })
      }
      .width('100%')
      .margin({ top: 10 })

  ```
  ![StyledString_lineHeight](figures/styled_string_lineHeight.png)

- 创建及应用文本字符间距对象（LetterSpacingStyle）

  ```ts
  import { LengthMetrics, LengthUnit } from '@kit.ArkUI'
  // xxx.ets
  @Entry
  @Component
  struct styled_string_demo7 {
    mutableStyledString: MutableStyledString = new MutableStyledString("运动35分钟", [
      {
        start: 0,
        length: 2,
        styledKey: StyledStringKey.LETTER_SPACING,
        styledValue: new LetterSpacingStyle(new LengthMetrics(20, LengthUnit.VP))
      }
    ]);
    controller: TextController = new TextController();

    async onPageShow() {
      this.controller.setStyledString(this.mutableStyledString)
    }

    build() {
      Column() {
        // 显示属性字符串
        Text(undefined, { controller: this.controller })
      }
      .width('100%')
    }
  }
  ```
  ![StyledString_letterSpacing](figures/styled_string_letterspacing.png)

## 设置段落样式

可通过[ParagraphStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#paragraphstyle)设置段落样式布局。下图显示了如何分割文本中的段落，段落以换行符 \n 结尾。

![paragraphs](figures/styledstringParagraphs.png)

以下代码示例展示了如何创建 ParagraphStyle 并应用。如果将 ParagraphStyle 附加到段落开头末尾或之间的任何位置均会应用样式，非段落区间内则不会应用样式。

  ```ts
  import { LengthMetrics } from '@kit.ArkUI'
  titleParagraphStyleAttr: ParagraphStyle = new ParagraphStyle({ textAlign: TextAlign.Center });
  //段落首行缩进15vp
  paragraphStyleAttr1: ParagraphStyle = new ParagraphStyle({ textIndent: LengthMetrics.vp(15) });
  //创建含段落样式的对象paragraphStyledString1
  paragraphStyledString1: MutableStyledString = new MutableStyledString("段落标题\n正文第一段落开始0123456789正文第一段落结束。", [
    {
      start: 0,
      length: 4,
      styledKey: StyledStringKey.PARAGRAPH_STYLE,
      styledValue: this.titleParagraphStyleAttr
    },
    {
      start: 0,
      length: 4,
      styledKey: StyledStringKey.LINE_HEIGHT,
      styledValue: new LineHeightStyle(new LengthMetrics(50))
    },{
    start: 0,
    length: 4,
    styledKey: StyledStringKey.FONT,
    styledValue: new TextStyle({ fontSize: LengthMetrics.vp(24), fontWeight: FontWeight.Bolder })
  },
    {
      start: 5,
      length: 3,
      styledKey: StyledStringKey.PARAGRAPH_STYLE,
      styledValue: this.paragraphStyleAttr1
    },
    {
      start: 5,
      length: 20,
      styledKey: StyledStringKey.LINE_HEIGHT,
      styledValue: this.lineHeightStyle1
    }
  ]);
  ```

  除了可以在创建属性字符串时就预设样式，也可以后续通过[replaceStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#replacestyle)清空原样式替换新样式, 同时需要在附加的文本组件controller上主动触发更新绑定的属性字符串。

  ```ts
  import { LengthMetrics } from '@kit.ArkUI'
  //段落不设置缩进配置最大行数及超长显示方式
  paragraphStyleAttr3: ParagraphStyle = new ParagraphStyle({ textAlign: TextAlign.End, maxLines: 1, wordBreak: WordBreak.BREAK_ALL, overflow: TextOverflow.Ellipsis});
  // 后续某个节点触发更新段落样式
  controller: TextController = new TextController();
  this.paragraphStyledString1.replaceStyle({
    start: 5,
    length: 3,
    styledKey: StyledStringKey.PARAGRAPH_STYLE,
    styledValue: this.paragraphStyleAttr3
  })
  this.controller.setStyledString(this.mutableStyledString3)
  ```

## 使用图片

可通过[ImageAttachment](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#imageattachment)来添加图片。

以下示例展示了如何将图片和文本附加到同一个MutableStyledString对象上，并实现图文混排。

  ```ts
  // xxx.ets
  import { image } from '@kit.ImageKit'
  import { LengthMetrics } from '@kit.ArkUI'

  @Entry
  @Component
  struct styled_string_demo4 {
    @State message: string = 'Hello World'
    imagePixelMap: image.PixelMap | undefined = undefined
    @State imagePixelMap3: image.PixelMap | undefined = undefined
    mutableStr: MutableStyledString = new MutableStyledString('123');
    controller: TextController = new TextController();
    mutableStr2: MutableStyledString = new MutableStyledString('This is set decoration line style to the mutableStr2', [{
      start: 0,
      length: 15,
      styledKey: StyledStringKey.DECORATION,
      styledValue: new DecorationStyle({
        type: TextDecorationType.Overline,
        color: Color.Orange,
        style: TextDecorationStyle.DOUBLE
      })
    }])

    async aboutToAppear() {
      console.info("aboutToAppear initial imagePixelMap")
      this.imagePixelMap = await this.getPixmapFromMedia($r('app.media.sea'))
    }

    private async getPixmapFromMedia(resource: Resource) {
      let unit8Array = await this.getUIContext().getHostContext()?.resourceManager?.getMediaContent({
        bundleName: resource.bundleName,
        moduleName: resource.moduleName,
        id: resource.id
      })
      let imageSource = image.createImageSource(unit8Array?.buffer?.slice(0, unit8Array?.buffer?.byteLength))
      let createPixelMap: image.PixelMap = await imageSource.createPixelMap({
        desiredPixelFormat: image.PixelMapFormat.RGBA_8888
      })
      await imageSource.release()
      return createPixelMap
    }

    leadingMarginValue: ParagraphStyle = new ParagraphStyle({ leadingMargin: LengthMetrics.vp(5)})
    //行高样式对象
    lineHeightStyle1: LineHeightStyle= new LineHeightStyle(new LengthMetrics(24));
    //Bold样式
    boldTextStyle: TextStyle = new TextStyle({ fontWeight: FontWeight.Bold });
    //创建含段落样式的对象paragraphStyledString1
    paragraphStyledString1: MutableStyledString = new MutableStyledString("\n品牌相纸 高清冲印30张\n限时直降5.15元 限量增送", [

      },
      {
        start: 14,
        length: 9,
        styledKey: StyledStringKey.FONT,
        styledValue: new TextStyle({ fontSize: LengthMetrics.vp(14), fontColor: '#B22222' })
      },
      {
        start: 24,
        length: 4,
        styledKey: StyledStringKey.FONT,
        styledValue: new TextStyle({ fontSize: LengthMetrics.vp(14), fontWeight: FontWeight.Lighter })

        length: 4,
        styledKey: StyledStringKey.LINE_HEIGHT,
        styledValue: this.lineHeightStyle1
      }
    ]);
    paragraphStyledString2: MutableStyledString = new MutableStyledString("\n￥16.21 3000+人好评", [
      {
        start: 0,

        styledValue: new LineHeightStyle(new LengthMetrics(60))
      },
      {

        length: 7,
        styledKey: StyledStringKey.FONT,
        styledValue: this.boldTextStyle
      },
      {
        start: 1,
        length: 1,
        styledKey: StyledStringKey.FONT,
        styledValue: new TextStyle({ fontSize: LengthMetrics.vp(18) })

      }
    ])

    build() {
      Row() {
        Column({ space: 10 }) {
          Text(undefined, { controller: this.controller })
            .copyOption(CopyOptions.InApp)
            .draggable(true)
            .backgroundColor('#FFFFFF')
            .borderRadius(5)

          Button('点击查看商品卡片')
            .onClick(() => {
              if (this.imagePixelMap !== undefined) {
                this.mutableStr = new MutableStyledString(new ImageAttachment({
                  value: this.imagePixelMap,
                  size: { width: 180, height: 160 },
                  verticalAlign: ImageSpanAlignment.BASELINE,

## 设置事件

可通过[GestureStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#gesturestyle)设置onClick、onLongPress事件来使文本响应点击长按事件。

除了初始化属性字符串对象即初始样式对象，亦可通过[setStyle](../reference/apis-arkui/arkui-ts/ts-universal-styled-string.md#setstyle)接口再叠加新样式或更新已有样式，同时需要在附加的文本组件controller上主动触发更新绑定的属性字符串。

  ```ts
