Android firing onTouch event for multiple ImageViews

Question

I have several ImageViews, and I want the onTouch event to fire for each of them when I drag my finger across multiple images. At present the onTouch event is only firing on

Answer 1

I think you need to use move event rather than touch event and compare getX and getY with the location of your views.

     @Override
    public boolean onTouchEvent(MotionEvent ev) {

        final int action = ev.getAction();

        switch (action) {

            // MotionEvent class constant signifying a finger-down event

            case MotionEvent.ACTION_DOWN: {
                break;
            }

            // MotionEvent class constant signifying a finger-drag event  

            case MotionEvent.ACTION_MOVE: {

                    X = ev.getX();
                    Y = ev.getY();
                    //compare here using a loop of your views
                    break;

            }

            // MotionEvent class constant signifying a finger-up event

            case MotionEvent.ACTION_UP:

                break;

        }
        return true;
    }

Answer 2

Yes, I had the same problem. The answer was to create a touch listener for the layout I embed my ImageViews in and then to calculate the X, Y position to know above which of my View am I. OnTouchListener is called only for the view it is connected to. I mean if it is called for an ImageView it won't fire until you start your motion onto that ImageView, as far as I know.
