Is it just gestures or are you trying to implement drag and drop<http://developer.android.com/guide/topics/ui/drag-drop.html>(because it sounds like that). Either way you could just intercept motion events in the parent view group that contains your images and let it handle your gesture recognition.
So let's say you create a derivative class "L" of your layout that contains the image views. You could override dispatchTouchEvent(MotionEvent)<http://developer.android.com/reference/android/view/ViewGroup.html#dispatchTouchEvent%28android.view.MotionEvent%29>of L and check for the following motion event states: *1. Gesture started (ACTION_DOWN)* Iterate your list of ImageView children of L and see if the touch event point is in one of them. If yes, your gesture starts. The View class has the method getGlobalVisibleRect(Rect, Point)<http://developer.android.com/reference/android/view/View.html#getGlobalVisibleRect(android.graphics.Rect,%20android.graphics.Point)>which can be used for checking if your touch event coordinate hits one of your image views. It would roughly look like the following (not tested since I'm not sure if these methods return locations in screen or window coordinate system, you may need to debug it): *Rect* r = new *Rect*();* *// should be class member you can reuse > float x = motionEvent.getRawX(); > float y = motionEvent.getRawY(); > > *for*(*ImageView* iv : imageViews) { > iv.getGlobalVisibleRect(r); > > *if*(r.contains(x, y)) { > // Touch event is inside image view > } > } > *2. Gesture ongoing (ACTION_MOVE)* If you visualize your gesture by drawing some trail or moving around the first touched image view then this is the right point to do so. Here you can update your view(s). *3. Gesture finished (ACTION_UP)* Here you need to iterate your ImageView children again in order to see if the finger has been lifted over another image view. In that case your gesture was successful. *4. Gesture canceled (ACTION_CANCEL)* Whatever your gesture is doing should be canceled here.
