如何设置间隔以从加速度计注册我的数据 - 运动传感器

问题描述

如何设置间隔以从 Accelerometer 注册我的数据，例如 1 秒从 1 个数据到另一个。 我尝试在这里更改延迟 sensorManager.registerListener(sensorEventListener,sensor,SensorManager.SENSOR_DELAY_norMAL);

但结果是一样的

这是我在 MainActivity 中的部分

  accelerometer.setListener(new Accelerometer.Listener() {
               //on translation method of accelerometer
               public void onTranslation(float tx,float ty,float ts){
                   SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM.dd 'at' HH:mm:ss");
                   String currentDateandTime = sdf.format(new Date());
                   tmp1[0] += "Accelerometer: X: " + (int) tx + " Y: " + (int) ty + " Z: " + (int) ts + "   Orario:  " + currentDateandTime + "\n";
                   Log.d("",tmp1[0]);

                   FileOutputStream fos = null;
                   try {
                       fos = new FileOutputStream(myExternalFile1);
                       fos.write(tmp1[0].getBytes());
                   } catch (FileNotFoundException e) {
                       e.printstacktrace();
                   } catch (IOException e) {
                       e.printstacktrace();
                   }
               }

           }
