接下来，用最短的package com.ray.test;import android.app.Activity;import android.os.Bundle;import android.hardware.SensorManager;import android.hardware.Sensor;import android.hardware.SensorEventListener;import android.hardware.SensorEvent;public class SensorTest extends Activity {private SensorManager sensorMgr;Sensor sensor = sensorMgr.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);private float x, y, z;protected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);sensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE);SensorEventListener lsn = new SensorEventListener() {public void onSensorChanged(SensorEvent e) {x = e.values[SensorManager.DATA_X]; y = e.values[SensorManager.DATA_Y]; z = e.values[SensorManager.DATA_Z];setTitle("x="+(int)x+","+"y="+(int)y+","+"z="+(int)z);}public void onAccuracyChanged(Sensor s, int accuracy) {}};//注册listener，第三个参数是检测的精确度sensorMgr.registerListener(lsn, sensor, SensorManager.SENSOR_DELAY_GAME);}}
