Fling gesture detection on grid layout

_x000D_ _x000D_ I want to get fling gesture detection working in my Android application. What I have is a GridLayout that contains 9 ImageViews. The source can be found here: Romain Guys's Grid Layout. That file I take is from Romain Guy's Photostream application and has only been slightly adapted. For the simple click situation I need only set the onClickListener for each ImageView I add to be the main activity which implements View.OnClickListener. It seems infinitely more complicated to implement something that recognizes a fling. I presume this is because it may span views? If my activity implements OnGestureListener I don't know how to set that as the gesture listener for the Grid or the Image views that I add. public class SelectFilterActivity extends Activity implements View.OnClickListener, OnGestureListener { ... If my activity implements OnTouchListener then I have no onFling method to override (it has two events as parameters allowing me to determine if the fling was noteworthy). public class SelectFilterActivity extends Activity implements View.OnClickListener, OnTouchListener { ... If I make a custom View, like GestureImageView that extends ImageView I don't know how to tell the activity that a fling has occurred from the view. In any case, I tried this and the methods weren't called when I touched the screen. I really just need a concrete example of this working across views. What, when and how should I attach this listener? I need to be able to detect single clicks also. // Gesture detection mGestureDetector = new GestureDetector(this, new GestureDetector.SimpleOnGestureListener() { public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { int dx = (int) (e2.getX() - e1.getX()); // don't accept the fling if it's too short // as it may conflict with a button push if (Math.abs(dx) > MAJOR_MOVE && Math.abs(velocityX) > Math.absvelocityY)) { if (velocityX > 0) { moveRight(); } else { moveLeft(); } return true; } else { return false; } } }); Is it possible to lay a transparent view over the top of my screen to capture flings? If I choose not to inflate my child image views from XML can I pass the GestureDetector as a constructor parameter to a new subclass of ImageView that I create? This is the very simple activity that I'm trying to get the fling detection to work for: SelectFilterActivity (Adapted from photostream). I've been looking at these sources: Detect Gestures - Tutorial SDK docs Calculator Code Nothing has worked for me so far and I was hoping for some pointers.
