HarmonyOS text组件设置copyOption

可以长按text粘贴也可以长按TextInput粘贴，参考示例：

import { LengthMetrics } from '@kit.ArkUI'
import { BusinessError, pasteboard } from '@kit.BasicServicesKit'

@Component
export struct TextCopy {
  @State text: string = "世界"

  @Builder
  MyMenu() {
    Menu() {
      MenuItem(this.CustomPasteButton())
    }
  }

  @Builder
  CustomPasteButton() {
    PasteButton({ buttonType: ButtonType.Normal, icon: PasteIconStyle.LINES })
      .onClick(() => {
        pasteboard.getSystemPasteboard().getData((err: BusinessError, pasteData: pasteboard.PasteData) => {
          if (err) {
            console.error(`Failed to get paste data. Code is ${err.code}, message is ${err.message}`);
            return;
          }
          // 剪贴板内容
          this.text = pasteData.getPrimaryText() || "";
        });
      })
  }

  @Builder
  CustomBoard() {

  }

  build() {
    Flex({ wrap: FlexWrap.Wrap, space: { main: LengthMetrics.vp(5), cross: LengthMetrics.vp(5) } }) {
      Text(this.text)
        .fontWeight(FontWeight.Bold)
        .bindContextMenu(this.MyMenu(), ResponseType.LongPress)
        .width('100%')

      TextInput({ text: this.text })
        .customKeyboard(this.CustomBoard)
    }
  }
}
