Android - GridView - GestureDetector doesn't work

Question

I have a problem with detecting fling gestures in my app. My layout consists of a GridView, couple of TextViews and buttons.

I implemented OnGestureListener:

public class MyActivity extends Activity implements OnGestureListener{
private GestureDetector myGesture ;

then in OnCreate:

myGesture = new GestureDetector(this);

and Overridden methods:

@Override
public boolean onTouchEvent(MotionEvent event){
    return myGesture.onTouchEvent(event);
}

}

@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
        float velocityY) {
    // TODO Auto-generated method stub
    try {
        if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
            return false;
        if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
            //right to left fling
        }  else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
            //left to right fling
        }
    } catch (Exception e) {
        // nothing
    }
    return false;
}

And this actually works great, but NOT on the GridView. Wherever outside the GridView I perform the fling, it works. On the GridView - there's absolutely no reaction. I have literally no idea, what to do about it, so thanks for any help in advance.

I actually found another solution, because the way I tried to do it simply didn't work and nobody knows why. I used GestureOverlayView instead, and it works great. Just had to add two swipe gestures to the gesture library.
