FloatingActionButton hide on list scroll

Question

Im using the FloatingActionButton from the android.support.design.widget package:

<android.support.design.widget.FloatingActionButton     android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:layout_alignParentBottom="true"     android:layout_alignParentEnd="true"     android:layout_marginBottom="20dp"     android:layout_marginEnd="16dp"     android:clickable="true"     android:backgroundTint="@color/primaryColor"     android:src="@drawable/ic_search_white_24dp"     app:borderWidth="0dp"     app:elevation="6dp"     app:backgroundTint="@color/primaryColorDark"     app:rippleColor="@color/accentColor" /> 

Is it possible to configure that button to hide with an animation when the listview is scrolling down and to show it again when listview is scrolling up to the top?

Those who are looking to make it with recyclerview can do this:

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {      @Override     public void onScrolled(RecyclerView recyclerView, int dx, int dy) {         if (dy > 0 || dy < 0 && fab.isShown())             fab.hide();     }      @Override     public void onScrollStateChanged(RecyclerView recyclerView, int newState) {         if (newState == RecyclerView.SCROLL_STATE_IDLE)             fab.show();         super.onScrollStateChanged(recyclerView, newState);     } });
