Why Is My Image Not Showing in Animated.View in React Native?
If you are a React Native developer trying to animate components, you might find yourself facing unexpected issues. One common problem, especially for beginners, is when an image does not show up when you place it inside an Animated.View. If you’ve recently attempted to animate heights or opacities but can’t seem to get the image to display, you are not alone. In this guide, we will explore the reasons behind this issue and how you can resolve it effectively.
Understanding the Problem
When you replace a Text component with an Image inside your Animated.View, you expect it to display as before. However, if you notice that the image does not appear, it can often be traced back to how the component is styled, particularly in regard to positioning and height. Let’s delve into the underlying reason why this occurs.
The Issue of Positioning
In React Native, when an element is positioned absolutely, it is removed from the normal flow of the layout. This means that its parent component, in this case, the Animated.View, won’t have defined dimensions, which causes it to collapse to a height of zero. As a result, the image is effectively invisible to the user, even though it still exists in the code.
The Solution
To make your image visible within the Animated.View, you can either apply a specific height to the Animated.View or adjust the image's positioning. Here’s how you can resolve the problem with clear examples.
Option 1: Set a Height for Animated.View
One of the simplest ways to ensure your image is displayed is by defining a height for the Animated.View. You can do this as follows:

This addition provides a concrete height to the Animated.View, ensuring that it has space to render your image correctly alongside whatever animations you wish to apply.
Option 2: Change Image Positioning
If you prefer to keep the Animated.View without a fixed height, another approach is to modify the TopImage component. Instead of using absolute positioning, you can use relative positioning with a height of 0 and animate it to its final height when needed.
Adjust TopImage like so:

Then, you can animate the height to your desired size dynamically based on user interactions, like scrolling.
Conclusion
When dealing with React Native and animations, understanding how layout mechanics work can save you a lot of time and frustration. If your image is not displaying inside an Animated.View, remember to check the height and positioning properties. By following the solutions outlined in this guide, you can troubleshoot and resolve this issue effectively, allowing your animations to come to life.
