Using getRotationMatrix and getOrientation in Android 2.1
- by aaronmar
I've been having issues with this for far too long. This code should output dx,dy,dz for the accelerometer, and a running total of the dx. It should also output azimuth, pitch, and roll.
I've used info from http://bit.ly/codeUsed, but to no avail.
This code does not correctly output pitch, azimuth, or roll. It outputs 0.0, -0.0, -0.0 for the last three textviews, respectively.
Please restore my sanity by helping me
switch (event.sensor.getType()) {
case Sensor.TYPE_ACCELEROMETER:
accelerometerValues = event.values.clone();
case Sensor.TYPE_MAGNETIC_FIELD:
geomagneticMatrix = event.values.clone();
sensorReady = true;
break;
default:
break;
}
if (geomagneticMatrix != null && accelerometerValues != null && sensorReady) {
sensorReady = false;
float[] R = new float[16];
float[] I = new float[16];
SensorManager.getRotationMatrix(R, I, accelerometerValues, geomagneticMatrix);
float[] actual_orientation = new float[3];
SensorManager.getOrientation(R, actual_orientation);
tvXCoordinate.setText(accelerometerValues[0] + "");
tvYCoordinate.setText(accelerometerValues[1] + "");
tvZCoordinate.setText(accelerometerValues[2] + "");
floatXTotal += accelerometerValues[0];
tvXTotal.setText(floatXTotal + "");
tvAzimuth.setText(actual_orientation[0] + "");
tvPitch.setText(actual_orientation[1] + "");
tvRoll.setText(actual_orientation[2] + "");
}
