Hi all!
I've been trying to get a simple test app working to show me the
orientation of the phone. The code I've used is below:
public class Main extends Activity implements SensorEventListener {
SensorEventListener listener;
TextView mainText;
SensorManager sensorMan;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mainText = (TextView)this.findViewById(R.id.mainString);
sensorMan =
(SensorManager)this.getSystemService(Context.SENSOR_SERVICE);
sensorMan.registerListener(
this,
sensorMan.getDefaultSensor(
SensorManager.SENSOR_ORIENTATION),
SensorManager.SENSOR_DELAY_NORMAL);
}
@Override
public void onAccuracyChanged(Sensor sensor, int accuracy) {
// TODO Auto-generated method stub
}
@Override
public void onSensorChanged(SensorEvent event) {
float[] values = event.values;
mainText.setText(
"AngleX: "+ values[0] +
"AngleY: "+ values[1] +
"AngleZ: "+ values[2] );
}
}
So from what I've seen everywhere, the angles should range somewhere
between -360 to 360 or -180 to 180. Something like that anyway. But
what I'm receiving when testing on my T-Mobile G2 is completely
different:
AngleX: -10 to 10
AngleY: -10 to 10
AngleZ: -11 to 11
Initially I assumed this was radians but it's outside of -PI to PI
(i.e. it'd be > 360 degrees which is contrary to all the blog posts
I've seen.
If anyone else has heard of this or seen this problem I'd love to know
what you did!
Any information or ideas are welcome!
Thanks a lot!
Andy.
