How to Pause a Video When Scrolling in React Native's ViewPager

In the world of mobile app development with React Native, creating a fluid user experience is crucial. Imagine this common scenario: your app includes a ViewPager from the @ react-native-community/viewpager package, which allows users to swipe through different pages. Some of these pages feature videos played using react-native-video. It's a great feature until you realize that when a user swipes to another page, the video continues to play in the background. This can be distracting as users might hear the video audio without seeing it.

The Problem

Upon scrolling to a new page, the video remains in play mode, which can lead to audio overlap and a confusing experience for users. The pressing question becomes: How do I pause the video when a user scrolls to another page in a ViewPager?

The Solution

The solution to this problem lies in tracking the current page and using it to control the play state of your videos. Below is a step-by-step guide to implementing this solution.

Step 1: Store the Current Page Value

You will need to keep track of which page is currently active. This can be done by using the state in your component. Set up your ViewPager and utilize the onPageScroll method to update your active page.

Here's a simplified version of how to do this:

Step 2: Utilize the paused Property

In each video component within your pages, use the paused property. By comparing the active page to the respective page index, the video will automatically pause when the user navigates to another page. For example, if the current page is not equal to the video’s corresponding page, the video will be paused.

Step 3: Managing Auto-Start (Optional)

If you do not want your videos to auto-start when the component mounts, you can introduce an isPlaying property in your state. This property can be managed to control when the video should start playing. Update the component as follows:

Conclusion

By implementing the above approach, you can ensure that your videos pause when users swipe between pages in a ViewPager. This enhancement results in a more seamless user experience and eliminates the auditory confusion of overlapping audio from multiple pages. Remember that user experience is paramount, and taking the time to implement these small adjustments can significantly improve your app's usability.

With this solution, you can confidently create engaging content for your users without compromising on usability. Happy coding!
