Hiding Toolbar with Swipe Actions

Question

I am trying to use an animation for that hides and shows a toolbar by detecting swiping gestures.It works but the issue is that when the toolbar is there(visible) it will repeat if you swipe up again and again and again. How can I prevent this from happening? I've try using variable to count each step then reset at the ending but that does not work either. Helping me past this would save a lot more time I've been stuck here for 2 weeks now.

CoreActivity.java

//Swipe Events WebSwipe
    WebSwipe = new Swipe(350, 700);
    WebSwipe.setListener(new SwipeListener() {
        @Override
        public void onSwipingLeft(final MotionEvent event) {
        }

        @Override
        public void onSwipedLeft(final MotionEvent event) {
        }

        @Override
        public void onSwipingRight(final MotionEvent event) {
        }

        @Override
        public void onSwipedRight(final MotionEvent event) {
        }

        @Override
        public void onSwipingUp(final MotionEvent event) {
        }

        @Override
        public void onSwipedUp(final MotionEvent event) {
            Animation ToolbarGone = AnimationUtils.loadAnimation(CoreActivity.this, R.anim.m_toolbar_gone);
            m_Toolbar.startAnimation(ToolbarGone);



        }

        @Override
        public void onSwipingDown(final MotionEvent event) {
        }

        @Override
        public void onSwipedDown(final MotionEvent event) {
               Animation ToolbarVisible = AnimationUtils.loadAnimation(CoreActivity.this, R.anim.m_toolbar_visible);
                m_Toolbar.startAnimation(ToolbarVisible);
        }
    });
}

Answer 1

Use visibility of view

if it is visible don't start animation.

Use animation listeners , so that you can set your view visibility to GONE

Answer 2

Try this code::

Add boolean to manage swipe gesture.

private boolean isSwipeUp=falese;


 //Swipe Events WebSwipe
 WebSwipe = new Swipe(350, 700);
 WebSwipe.setListener(new SwipeListener() {
    @Override
    public void onSwipingLeft(final MotionEvent event) {
    }

    @Override
    public void onSwipedLeft(final MotionEvent event) {
    }

    @Override
    public void onSwipingRight(final MotionEvent event) {
    }

    @Override
    public void onSwipedRight(final MotionEvent event) {
    }

    @Override
    public void onSwipingUp(final MotionEvent event) {
    }

    @Override
    public void onSwipedUp(final MotionEvent event) {

        if(!isSwipeUp)
        {
            Animation ToolbarGone = AnimationUtils.loadAnimation(CoreActivity.this, R.anim.m_toolbar_gone);
            m_Toolbar.startAnimation(ToolbarGone);
            isSwipeUp = true;
        }


    }

    @Override
    public void onSwipingDown(final MotionEvent event) {
    }

    @Override
    public void onSwipedDown(final MotionEvent event) {
           Animation ToolbarVisible = AnimationUtils.loadAnimation(CoreActivity.this, R.anim.m_toolbar_visible);
            m_Toolbar.startAnimation(ToolbarVisible);
            isSwipeUp = false;
    }
  });
}
