Question 1

How to speed up the parallax animation in RNParallax?

Accepted Answer

Adjust the extraScrollHeight and backgroundImageScale props; lower values can make animations feel snappier, but test on target devices to balance performance. The README mentions these are configurable for custom effects.

Question 2

RNParallax vs react-native-parallax-scroll-view: which is better?

Accepted Answer

RNParallax is more customizable and actively maintained, with better iPhone X support and more props. Choose it for finer control; the older library might be simpler but less updated.

Question 3

Can I use a video background instead of an image in RNParallax?

Accepted Answer

Not directly; the backgroundImage prop only accepts image sources. You'd need to overlay a video component manually, which isn't documented and could break parallax synchronization.

Question 4

How to make the navbar hide completely on scroll in RNParallax?

Accepted Answer

Set alwaysShowNavBar to false and use renderNavBar to conditionally render based on scroll position, but this requires custom logic beyond the basic props.

Question 5

Does RNParallax work with React Navigation's header?

Accepted Answer

It can conflict; use renderNavBar to mimic navigation headers, but direct integration isn't covered in the docs, potentially leading to UI inconsistencies.

Question 6

What's the performance impact of RNParallax on Android?

Accepted Answer

Parallax animations and image scaling can strain low-end devices; the backgroundImageScale prop may cause jank if set too high, so profile on real hardware.
