Displaying Accelerometer Values in Android

Question

I am looking for some source code or example code detailing how to display the values of the accelerometer in Android. Preferably, the values would show acceleration in the x direction, y direction, and z direction.

I am an Android noob so any help is much appreciated.

Have you checked out the Accelerometer example in the android samples? You could always try something like this (which I got from here):

 public class SensorActivity extends Activity implements SensorEventListener {
     private final SensorManager mSensorManager;
     private final Sensor mAccelerometer;

     public SensorActivity() {
         mSensorManager = (SensorManager)getSystemService(SENSOR_SERVICE);
         mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
     }

     protected void onResume() {
         super.onResume();
         mSensorManager.registerListener(this, mAccelerometer, SensorManager.SENSOR_DELAY_NORMAL);
     }

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

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

     public void onSensorChanged(SensorEvent event) {
       //Right in here is where you put code to read the current sensor values and 
       //update any views you might have that are displaying the sensor information
       //You'd get accelerometer values like this:
       if (event.sensor.getType() != Sensor.TYPE_ACCELEROMETER)
            return;
        float mSensorX, mSensorY;
        switch (mDisplay.getRotation()) {
            case Surface.ROTATION_0:
                mSensorX = event.values[0];
                mSensorY = event.values[1];
                break;
            case Surface.ROTATION_90:
                mSensorX = -event.values[1];
                mSensorY = event.values[0];
                break;
            case Surface.ROTATION_180:
                mSensorX = -event.values[0];
                mSensorY = -event.values[1];
                break;
            case Surface.ROTATION_270:
                mSensorX = event.values[1];
                mSensorY = -event.values[0];
         }
     }
 }
