above in following image can see happens when have cursor in scrollview. blue line above navigation bar. under happens when have cursor in relativelayout inside scrollview (which how it's supposed be): android studio

could tell why scrollview not showing content?

this how on emulator. emulator

i've fixed using nestedscrollview instead of scrollview, because fragment initiated in coordinatorlayout. didn't know nestedscrollvew work then.
