Android sensor usage

Public class sensortest extends activity implements sensoreventlistener {sensormanager = NULL; // For each values textview outputx; textview outputy; textview outputz; // for orientation values textview outputx2; textview outputy2; textview outputz2; @ override public void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); // initialize sensormanager = (sensormanager) getsystemservice (sensor_service); setcontentview (R. layout. main); // just some textviews, for data output outputx = (textview) findviewbyid (R. id. textview01); outputy = (textview) findviewbyid (R. id. textview02); outputz = (textview) findviewbyid (R. id. textview03); outputx2 = (textview) findviewbyid (R. id. textview04); outputy2 = (textview) findviewbyid (R. id. textview05); outputz2 = (textview) findviewbyid (R. id. textview06);} // register the listener @ override protected void onresume () {super. onresume (); sensormanager. registerlistener (this, sensormanager. getdefasensensor (sensor. type_accelerometer), sensormanager. sensor_delay_game); sensormanager. registerlistener (this, sensormanager. getdefasensensor (sensor. type_orientation), sensormanager. sensor_delay_game);} // log out of listening in onstop @ override protected void onstop () {super. onstop (); sensormanager. unregisterlistener (this, sensormanager. getdefasensensor (sensor. type_accelerometer); sensormanager. unregisterlistener (this, sensormanager. getdefasensensor (sensor. type_orientation);} // public void onsensorchanged (sensorevent event) {synchronized (this) {Switch (event. sensor. getType () {Case sensor. type_accelerometer: outputx. settext ("X:" + float. tostring (event. values [0]); outputy. settext ("Y:" + float. tostring (event. values [1]); outputz. settext ("Z:" + float. tostring (event. values [2]); break; Case sensor. type_orientation: outputx2.settext ("X:" + float. tostring (event. values [0]); outputy2.settext ("Y:" + float. tostring (event. values [1]); outputz2.settext ("Z:" + float. tostring (event. values [2]); break ;}}// more precise change @ override public void onaccuracychanged (sensor, int accuracy ){}}

To sum things up, to access sensor data you have to do the following things:
1. Check sensor availability.
2. Register a listener to a sensormanager.
3. Catch the needed data, from onsensorchanged.
4. unregister the sensormanager's listener.
