Question

I\'m attempting to utilize Gestures within a fragment; I have the following inside of a FragmentActivity which handles my details fragment. What I am attempting to have hap

Answer 1

Looks like the following issue explains this: Android: GestureDetector won't catch Gestures

Additionally here is the result:

The solution is actually to Override the onDown method and return true; otherwise the gesture detector will stop and not detect the up:

        final GestureDetector gesture = new GestureDetector(getActivity(),
            new GestureDetector.SimpleOnGestureListener() {

                @Override
                public boolean onDown(MotionEvent e) {
                    return true;
                }

                @Override
                public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
                    float velocityY) {
                    Log.i(Constants.APP_TAG, "onFling has been called!");
                    final int SWIPE_MIN_DISTANCE = 120;
                    final int SWIPE_MAX_OFF_PATH = 250;
                    final int SWIPE_THRESHOLD_VELOCITY = 200;
                    try {
                        if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH)
                            return false;
                        if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
                            && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                            Log.i(Constants.APP_TAG, "Right to Left");
                        } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
                            && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
                            Log.i(Constants.APP_TAG, "Left to Right");
                        }
                    } catch (Exception e) {
                        // nothing
                    }
                    return super.onFling(e1, e2, velocityX, velocityY);
                }
            });

        v.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                return gesture.onTouchEvent(event);
            }
        });
