I am now forwading touch event to gestureDetector but let me know what to
add more ?
@Override
*public* *boolean* onTouchEvent(MotionEvent event){
*this*.detector.onTouchEvent(event);
*return* *super*.onTouchEvent(event);
}
@Override
*public* *boolean* onDoubleTap(MotionEvent e) {
// *TODO* Auto-generated method stub
mapView.getController().zoomIn();
*return* *false*;
}
@Override
*public* *boolean* onDoubleTapEvent(MotionEvent e) {
// *TODO* Auto-generated method stub
*return* *false*;
}
