CoordinatorLayout with NestedScroll and CollapsingToolbarLayout doesn't scroll to bottom

Question

I am having an issue with CoordinatorLayout and CollapsingToolbarLayout, the toolbar is working fin, but when I scroll the activity to bottom, it does never get to the bottom it only gets until the 2nd row before the last one.

Is there any problem in my xml? (I am loading the text from strings.xml programmatically)

This is my Layout

<android.support.design.widget.CoordinatorLayout

Seems that behavior you have described is caused by layout_gravity attribute of your NestedScrollView. Try to remove it.
