Retrieving sensor events
suggest changeRetrieving sensor information from the onboard sensors:
public class MainActivity extends Activity implements SensorEventListener {
private SensorManager mSensorManager;
private Sensor accelerometer;
private Sensor gyroscope;
float[] accelerometerData = new float[3];
float[] gyroscopeData = new float[3];
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mSensorManager = (SensorManager) getSystemService(SENSOR_SERVICE);
accelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
gyroscope = mSensorManager.getDefaultSensor(Sensor.TYPE_GYROSCOPE);
}
@Override
public void onResume() {
//Register listeners for your sensors of interest
mSensorManager.registerListener(this, accelerometer, SensorManager.SENSOR_DELAY_FASTEST);
mSensorManager.registerListener(this, gyroscope, SensorManager.SENSOR_DELAY_FASTEST);
super.onResume();
}
@Override
protected void onPause() {
//Unregister any previously registered listeners
mSensorManager.unregisterListener(this);
super.onPause();
}
@Override
public void onSensorChanged(SensorEvent event) {
//Check the type of sensor data being polled and store into corresponding float array
if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER) {
accelerometerData = event.values;
} else if (event.sensor.getType() == Sensor.TYPE_GYROSCOPE) {
gyroscopeData = event.values;
}
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// TODO Auto-generated method stub
}
}
Found a mistake? Have a question or improvement idea?
Let me know.
