Avoiding ImageView Blink in RecyclerView: A Guide for Android Developers

RecyclerView is a powerful component in Android that allows for efficient scrolling of a list of items. However, when it comes to displaying images, developers often encounter a frustrating issue: images blinking or flashing when the RecyclerView is refreshed. If you’re facing this problem, don’t worry—this guide will tackle the causes of image blinking and provide a practical solution using Glide.

The Problem: Image Blink in RecyclerView

When you refresh items in a RecyclerView, especially those containing images, the images may flicker or blink. This can detract from the user experience and give the impression of a poorly performing application. Developers often resort to setting stable IDs to mitigate this issue, but in some cases, it may not work, especially if the model class uses string identifiers. This is a common situation that many Android developers face.

For instance, your implementation might look like this:

While this code snippet utilizes Glide for image loading, it doesn't prevent the blinking effect.

The Solution: Using SimpleTarget with Glide

What is SimpleTarget?

SimpleTarget is a class provided by Glide that allows you to load images directly into your views by bypassing the standard ImageView. Using SimpleTarget, you can have finer control over how and when your images appear, reducing the chances of flickering as images load.

Implementing SimpleTarget

Here’s how to implement SimpleTarget in your RecyclerView’s adapter to solve the blinking issue:

Change Your Glide Loading Code

Replace your existing Glide loading code with the following implementation:

Breakdown of the Implementation

asBitmap(): Loads the image as a Bitmap, which is essential for using SimpleTarget effectively.

diskCacheStrategy(DiskCacheStrategy.NONE): Ensures that images are not cached, leading to immediate loading of fresh images.

skipMemoryCache(true): Prevents images from being stored in memory, further optimizing performance during rapid refreshes.

dontAnimate(): Disables animations, which helps in minimizing blinking during the update of images.

Benefits of Using SimpleTarget

The use of SimpleTarget to load images mitigates the visual disruption caused by flashing images, enhancing user perception and application fluidity. When you set images directly through this method, you reduce the potential for conflicts during view recycling.

Conclusion

Image blinking in RecyclerView can be a frustrating issue for developers and users alike. By implementing SimpleTarget in your image loading logic with Glide, you can effectively prevent this issue and improve the overall user experience of your Android application.

By following the steps outlined in this post, you'll be well-equipped to tackle the blinking image problem in your RecyclerViews. Happy coding!
