HarmonyOS 如何获取设备朝向

获取设备旋转角度参考如下demo:

/**
  * 注册方向传感器，注意只能放到Ability中注册
  */
 private doRegister() {
   try {
     sensor.on(sensor.SensorId.ORIENTATION, (data: sensor.OrientationResponse) => {
       log.info('[x, y, z]: [' + Math.round(data.beta) + ', ' + Math.round(data.gamma) + ',' + Math.round(data.alpha) + ']');
     }, {
       interval: 100000000
     });
   } catch (error) {
     let e: BusinessError = error as BusinessError;
     log.error(`Failed to invoke once. Code: ${e.code}, message: ${e.message}`);
   }
 }

 /**
  * 反注册方向传感器
  */
 private doUnRegister() {
   sensor.off(sensor.SensorId.ORIENTATION);
 }
