Answer 1

参考示例demo：

import { sensor } from '@kit.SensorServiceKit';

@Entry
@Component
struct Twist {
  @State x: string = ''
  @State y: string = ''
  @State z: string = ''
  aboutToAppear(): void {
    sensor.on(sensor.SensorId.GYROSCOPE, this.callback.bind(this))
  }

  aboutToDisappear(): void {
    sensor.off(sensor.SensorId.GYROSCOPE, this.callback.bind(this))
  }

  callback(data: sensor.GyroscopeResponse) {
    this.x = data.x.toString()
    this.y = data.y.toString()
    this.z = data.z.toString()
    console.info('Succeeded in invoking once. X-coordinate component: ' + data.x);
    console.info('Succeeded in invoking once. Y-coordinate component: ' + data.y);
    console.info('Succeeded in invoking once. Z-coordinate component: ' + data.z);
  }

  build() {
    Column() {
      Text(this.x)
      Text(this.y)
      Text(this.z)
    }
  }
}
