Android 重力感应 测试代码

private float x, y, z;
@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 sensorMgr = (SensorManager) getSystemService(SENSOR_SERVICE);
 Sensor sensor = sensorMgr.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
 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);
}

将x、y、z的坐标显示出来。
