Orientation sensor problem.

 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. */
    public void onCreate(Bundle savedInstanceState) {


        mainText = (TextView)this.findViewById(R.id.mainString);

        sensorMan =

        public void onAccuracyChanged(Sensor sensor, int accuracy) {
                // TODO Auto-generated method stub


        public void onSensorChanged(SensorEvent event) {

                float[] values = event.values;
                                "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

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!

 Did you ever get to the bottom of this?
I think I'm having a similar problem.

1. Question about using LayoutInflater

I have a question about using LayoutInflater.

I have a class which inherits from 'View'.

It calls

LayoutInflater inflater =
                if (inflater != null) {
                        inflater.inflate(R.layout.mycontent, null);

inflate returns with no exception.

But then, when I do this:
mRowLayout = (RelativeLayout)findViewById(R.id.row_layout);

I get a null pointer for mRowLayout.

Can you please tell me why? Or how to fix my problem?
