本文介绍如何使用Android的SensorManager接口监听并获取设备的加速度计数据，包括初始化传感器、注册监听器以及读取加速度计的X、Y、Z轴的加速值。

import android.content.Context;
import android.hardware.Sensor;
import android.hardware.SensorEvent;
import android.hardware.SensorEventListener;
import android.hardware.SensorManager;

public class AccelerometerHandler implements SensorEventListener {
    private float accelX;
    private float accelY;
    private float accelZ;

    public AccelerometerHandler(Context context) {
        SensorManager manager = (SensorManager) context.getSystemService(Context.SENSOR_SERVICE);
        if (manager.getSensorList(Sensor.TYPE_ACCELEROMETER).size() != 0) 
        {
            Sensor accelerometer = manager.getSensorList(Sensor.TYPE_ACCELEROMETER).get(0);
            manager.registerListener(this, accelerometer, SensorManager.SENSOR_DELAY_GAME);
        }
    }

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

    @Override
    public void onSensorChanged(SensorEvent event) {
        accelX = event.values[0];
        accelY = event.values[1];
        accelZ = event.values[2];
    }

    public float getAccelX() {
        return accelX;
    }

    public float getAccelY() {
        return accelY;
    }

    public float getAccelZ() {
        return accelZ;
    }
}
