AccelerorMeter Sensor 사용 소스

1. Activity 생성(onCreate)시 SensorService를 얻어온다.

SensorMamager sensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);

Sensor accelerormeterSensor = sensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);

2. Sensor가 잘 생성되었다면은 SensorManager에 등록을 한다.

if (accelerormeterSensor != null)

sensorManager.registerListener(this, accelerormeterSensor ,SensorManager.SENSOR_DELAY_GAME);

3. 등록까지 완료 되었다면은 이제 가속도센서(AccelerorMeterSensor)를 사용할 수 있다.

public void onSensorChanged(SensorEvent event) {

if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {

// 원하는 기능을 사용 가능함.

}
