HarmonyOS 鸿蒙Next Array的sort排序方法，在NEXT0.0.31不生效，NEXT0.0.26以及之前都没问题

// xxx.ets

class KeyboardItemData {
  num: number
  name: string

  constructor(num: number,
    name: string) {
    this.num = num
    this.name = name
  }
}

[@Entry](/user/Entry)
[@Component](/user/Component)
struct QRCodeExample {
  private value: string = 'hello world'

  build() {
    Column({ space: 5 }) {
      Button('测试').onClick(() => {
        const Keyboard_ABC: Array<Array<KeyboardItemData>> = [

          [

            new KeyboardItemData(49, '1'),

            new KeyboardItemData(50, '2'),

            new KeyboardItemData(51, '3'),

            new KeyboardItemData(52, '4'),

            new KeyboardItemData(53, '5'),

            new KeyboardItemData(54, '6'),

            new KeyboardItemData(55, '7'),

            new KeyboardItemData(56, '8'),

            new KeyboardItemData(57, '9'),

            new KeyboardItemData(48, '0'),

          ].sort((a, b) => {
            return 0.5 - Math.random();
          })]

        console.log(JSON.stringify(Keyboard_ABC));
      })
    }.width('100%').margin({ top: 5 })
  }
}

我这边代码生效的，你的手机系统还是beta版本，建议升级下版本
