You could still try the approach I described by getting rawX and rawY from the motion event and match it with the global rect position of the target view. Motion event coordinates are usually in a local coordinate system. I guess the local coordinate system is the one of the ImageView you start your gesture with, hence the too big numbers when you get your ACTION_CANCEL on the other view.
