Pass scroll event to another view

Question

I have been using android design support library for collapsing toolbar layout. Everything works fine except that I want to scroll the whole view on scrolling content in col

Answer 1

Your pager content needs to have nested scrolling enabled. The easiest way to accomplish this is to just wrap it in a NestedScrollView:

fragment_image.xml

However this causes the parent height of the ImageView to be indeterminate, so you have to set it to some fixed height.
