I am setting a toolbar animation with help of nested scroll view. but the setOnScrollChangeListener is not working properly.
here the issue is
setOnScrollChangeListeneris not working. scrolling is not detecting
please help me to solve this issue. I think the issue is with my xml design because I just used the code in my demo project and it works perfectly. but in here it is not working. the scrolling is not detected.
this is my xml file

nested_content.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
@Override
public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
Log.e("ProductFragment","position button " + scrollX + "======= scrollY " + scrollY);
if (scrollY < oldScrollY) { // up
animateFab(true);
animateSearchBar(true);
colapseBar.setVisibility(View.GONE);
}
if (scrollY > oldScrollY) { // down
animateFab(false);
animateSearchBar(false);
colapseBar.setVisibility(View.VISIBLE);
}
}
});
