bonjour 

je veux avoir les angles rotation sur x , y et z

ces valeurs 

mais mon téléphone me renvoi ces valeurs  il me renvoi des valeurs que je ne comprend pas 

voici mon code

public class graphic extends Activity implements SensorEventListener {

    private SensorManager mSensorManager;
    Sensor accelerometer;
    Sensor magnetometer;
    private float azimut,pitch,roll;
    private TextView dx;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);    // Register the sensor listeners
        mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
        accelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
        magnetometer = mSensorManager.getDefaultSensor(Sensor.TYPE_MAGNETIC_FIELD);
        dx = (TextView)findViewById(R.id.width);
    }

    protected void onResume() {
        super.onResume();
        mSensorManager.registerListener(this, accelerometer, SensorManager.SENSOR_DELAY_UI);
        mSensorManager.registerListener(this, magnetometer, SensorManager.SENSOR_DELAY_UI);
    }

    protected void onPause() {
        super.onPause();
        mSensorManager.unregisterListener(this);
    }

    public void onAccuracyChanged(Sensor sensor, int accuracy) {  }

    float[] mGravity;
    float[] mGeomagnetic;
    public void onSensorChanged(SensorEvent event) {
        if (event.sensor.getType() == Sensor.TYPE_ACCELEROMETER)
            mGravity = event.values;
        if (event.sensor.getType() == Sensor.TYPE_MAGNETIC_FIELD)
            mGeomagnetic = event.values;
        if (mGravity != null && mGeomagnetic != null) {
            float R[] = new float[9];
            float I[] = new float[9];
            boolean success = SensorManager.getRotationMatrix(R, I, mGravity, mGeomagnetic);
            if (success) {
                float orientation[] = new float[3];
                SensorManager.getOrientation(R, orientation);
                azimut = orientation[0]; // orientation contains: azimut, pitch and roll
                pitch = orientation[1];
                roll = orientation[2];
                dx.setText(azimut+" "+pitch+" "+roll);
            }
        }
    }
}

merci
