public class MyLocationOverlayProxy extends com.amap.mapapi.map.MyLocationOverlay{

private Location mLocation;
protected final Paint mPaint = new Paint();
protected final Paint mCirclePaint = new Paint();
private Bitmap gps_marker=null;
private Point mMapCoords = new Point();
private final float gps_marker_CENTER_X;
private final float gps_marker_CENTER_Y;
private final LinkedList mRunOnFirstFix = new LinkedList();
public MyLocationOverlayProxy(amap amap, MapView mMapView) {

super(amap, mMapView);
gps_marker = ((BitmapDrawable) amap.getResources().getDrawable(
R.drawable.marker_gpsvalid)).getBitmap();
gps_marker_CENTER_X = gps_marker.getWidth() / 2 - 0.5f;
gps_marker_CENTER_Y= gps_marker.getHeight() / 2 - 0.5f;
}
