title: Drawing an elevation profile between two markers in Maps API V2
body: <p>I'm a novice so I apologize in advance if my code and/or understanding is simplistic. I am attempting to build an app that allows me to select different markers and show not only the distance to the selected marker from my current location, but an elevation profile as well. I saw something similar to this in a Google Labs option for Maps where it allowed you to draw a line between two points and then it would give you a graph that showed the elevations between those two points. I've tried to find some answers here, but it seems nobody is really talking about this at all so I thought I'd ask. The code I'm currently using to give me the distance is:</p>
  
  <pre><code>  if (marker.equals(windy)) 
    {
        //handle click here
        WINDYINFO.setVisibility(View.VISIBLE);    
  
        float[] results = new float[1];
        Location.distanceBetween(myPosition.latitude, myPosition.longitude,
                        WDY.latitude, WDY.longitude, results);
        TextView distanceView = (TextView) findViewById(R.id.windydistance);
        results[0] *= 0.000621371192;
        distanceView.setText(String.valueOf(results[0]));
    }
  </code></pre>
  
  <p>myPosition will always be my location according to GPS, and WDY is the elevation for the windy marker. How would I go about doing what I mentioned above, here, so that I can take the data and display it in my activity?</p>
