我在ViewFlipper内有一个ListView，当用户在屏幕上滑动时会翻转它。单击ListView将打开浏览器。有时在我刷卡时，它被检测为对ListView的触摸，并会打开浏览器。这可能很烦人。如何防止这种情况发生？

class MyGestureDetector extends SimpleOnGestureListener {
        @Override
        public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
            try {
                if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
                    return false;
                // right to left swipe
                if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    viewFlipper.setInAnimation(slideLeftIn);
                    viewFlipper.setOutAnimation(slideLeftOut);
                    viewFlipper.showNext();
                } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                    viewFlipper.setInAnimation(slideRightIn);
                    viewFlipper.setOutAnimation(slideRightOut);
                    viewFlipper.showPrevious();
                }

                if (viewFlipper.getDisplayedChild() == 0) {
                    // TODO: light up left
                    flipperPosition = 0;
                } else if (viewFlipper.getDisplayedChild() == 1) {
                    // TODO: light up middle
                    flipperPosition = 1;
                } else if (viewFlipper.getDisplayedChild() == 2) {
                    // TODO: light up right
                    flipperPosition = 2;
                }
            } catch (Exception e) {
                System.out.println(e);
            }
            return false;
        }
    }

protected MotionEvent downStart = null;

        public boolean onInterceptTouchEvent(MotionEvent event) {

            switch(event.getAction()) {  
            case MotionEvent.ACTION_DOWN:  
                // keep track of the starting down-event  
                downStart = MotionEvent.obtain(event);  
                break;  
            case MotionEvent.ACTION_MOVE:  
                // if moved horizontally more than slop*2, capture the event for ourselves  
                float deltaX = event.getX() - downStart.getX();  
                if(Math.abs(deltaX) > ViewConfiguration.getTouchSlop() * 2)  
                    return true;  
                break;  
            }

            // otherwise let the event slip through to children  
            return false;  
        }
