需要在onCopy，onPaste禁止系统默认复制粘贴，再通过getSpans获取复制的内容样式，自定义复制粘贴。 以下是简化demo参考：

import { JSON } from '@kit.ArkTS';
@Entry
@Component
struct RichEditorExample {
  controller: RichEditorController = new RichEditorController()
  controller1: RichEditorController = new RichEditorController()
  @State content: string = ""
  private start: number = -1;
  private end: number = -1;
  @State textStyle: RichEditorTextStyle = {}
  @State textContent: string = ''
  @State imageStyle: RichEditorImageSpanStyle = {}
  @State imageStr: ResourceStr | undefined = ''

  build() {
    Column() {
      RichEditor({ controller: this.controller })
        .height(200)
        .borderWidth(1)
        .borderColor(Color.Red)
        .width("100%")
        .onReady(() => {
          this.controller.addTextSpan("012345",
            {
              style:
              {
                fontColor: Color.Orange,
                fontSize: 30
              }
            })
          this.controller.addImageSpan($r("app.media.icon"),
            {
              imageStyle:
              {
                size: [57, 57]
              }
            })
          this.controller.addImageSpan($r("app.media.icon"),
            {

                size: [57, 57]
              }
            })
          this.controller.addTextSpan("56789",

                fontSize: 30
              }
            })
        })
        .onCut((event:CutEvent) => {
          event.preventDefault!()
          console.log('测试log：onCut')
        })
        .onSelect((value: RichEditorSelection) => {
          this.start = value.selection[0];
          this.end = value.selection[1];
        })
        .onCopy((event:CopyEvent) => {

                console.log('输出：this.textContent',this.textContent)
                this.textStyle = (item as RichEditorTextSpanResult).textStyle
                console.log('输出：this.textStyle',JSON.stringify(this.textStyle))
            }
          })

在HarmonyOS鸿蒙Next中，RichEditor自定义菜单中复制文本可以通过调用RichEditor的copyText方法实现。首先获取RichEditor实例，然后使用getSelectedText方法获取选中的文本内容，最后调用copyText方法将文本复制到剪贴板。具体代码示例如下：

let richEditor = this.$refs.richEditor as RichEditor;
let selectedText = richEditor.getSelectedText();
richEditor.copyText(selectedText);

确保在自定义菜单的点击事件中调用上述逻辑即可实现文本复制功能。

在HarmonyOS Next中，RichEditor组件要实现自定义菜单的文本复制功能，可以通过以下方式实现：

  1. 使用RichEditor的getSelection()方法获取当前选中的文本内容：
const selection = richEditor.getSelection();
const selectedText = selection.getText();
  1. 将获取到的文本内容写入系统剪贴板：
import pasteboard from '@ohos.pasteboard';

let systemPasteboard = pasteboard.getSystemPasteboard();
let record = pasteboard.createPlainTextRecord(selectedText);
systemPasteboard.setPasteRecord(record);
  1. 在自定义菜单的点击事件中触发上述操作：
customMenu.onClick(() => {
    // 执行复制逻辑
});

注意：需要先在module.json5中声明pasteboard权限：

"requestPermissions": [
    {
        "name": "ohos.permission.PASTEBOARD_WRITE"
    }
]
