where idea toolbar collapsing when scrolled (down?). there problem touch event occurred. if scroll initiated on element except recyclerview, works charm. if scroll touch initiated on recyclerview, nestedscrollview starts scrolling without toolbar collapse or expand. recyclerviews use custom layout manager, wraps content (each recyclerview has few items). here question. how tell recyclerview not interfere nestedscrollview's collapsing/expanding behavior?

i had same problem nestedscrollview used

android:nestedscrollingenabled="false" 

and problem gone, please try add , tell me if works

good luck
