I have a NestedScrollView as the root element and there is a button that overlaps some of the content. How to track that NestedScrollView scrolls down to hide the button at this moment?

    You need to pass your implementation of the OnScrollChangeListener interface to the setOnScrollChangeListener method of your NestedScrollView . There is only one method in this interface.

     void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY);

    Using the parameters scrollY and oldScrollY you can determine where the user scrolls.
