java - Android 计步器显示不正确的步骤

Question

我在 Java 中创建了一个简单的 android 计步器。我有计步器工作，但由于某种原因，当我启动应用程序时，它以 62000 步开始。我没有在我的代码中的任何地方硬编码这个值，我不确定为什么会这样。下面我提供截图和代码片段。对此有什么想法吗？

用户界面是什么样的

public class Pedometer extends AppCompatActivity implements SensorEventListener {
    private SensorManager sensorManager;
    private TextView count;
    private boolean running;
    private Button reset;
    private CircularProgressBar circularProgressBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_pedometer);
        getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        count = findViewById(R.id.stepTextView);
        reset = findViewById(R.id.resetSteps);
        circularProgressBar = findViewById(R.id.circularBar);
        sensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
        reset.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                count.setText("0");
            }
        });
    }

    @Override
    protected void onResume() {
        super.onResume();
        running = true;
        Sensor countSensor = sensorManager.getDefaultSensor(Sensor.TYPE_STEP_COUNTER);
        if(countSensor != null) {
            sensorManager.registerListener(Pedometer.this,countSensor,SensorManager.SENSOR_DELAY_UI);
        } else {
            Toast.makeText(Pedometer.this,"Sensor not found.",Toast.LENGTH_SHORT).show();
        }
    }

    @Override
    protected void onPause() {
        super.onPause();
        running = false;
    }

    @Override
    protected void onStop() {
        super.onStop();
        running = false;
    }

    @Override
    public void onSensorChanged(SensorEvent event) {
        if(running) {
            int currentSteps = (int) event.values[0];
            count.setText(String.valueOf(currentSteps));
            circularProgressBar.setProgressWithAnimation(currentSteps);
        }
    }

    @Override
    public void onAccuracyChanged(Sensor sensor, int accuracy) {

    }
}
