How can I set visibily gone on scrolling downwards?

I have kept a button in my scroll view which should be visible only when I am scrolling up and should get invisible as I scroll down like in paytm. It is a simple scroll view inside a fragment.

      scrollBtn.setVisibility(View.GONE);

    scrollView.setOnScrollChangeListener(new View.OnScrollChangeListener() {
        @Override
        public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
            scroll.setVisibility(View.VISIBLE);

        }
    });

    scrollBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            scrollView.scrollTo(0, 0);
        }
    });

This should help you.

Code

scrollView.setOnScrollChangeListener(new View.OnScrollChangeListener() {
           @Override
           public void onScrollChange(View view, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
               //Scrolling down
               if(scrollY<oldScrollY){
                   scrollBtn.setVisibility(View.GONE);
               }else{
                   scrollBtn.setVisibility(View.VISIBLE);
               }
           }
       });
