Display Images Downloaded from an API in a ListView with Text in Android

Displaying images in an Android application fetched from an API can be challenging, especially when it comes to populating these images in a ListView alongside text. This guide will walk you through the steps necessary to implement this feature effectively, ensuring your application stands out with a well-organized interface.

Problem Overview

When developing an Android application, you might find yourself needing to display a list of items that includes both images and text. In our example, we want to showcase films retrieved from an API, where each film is represented by an image and its respective name. Although we already have an ImageDownloader class to download images, integrating it with a ListView requires implementing a custom adapter.

Steps to Implement the Solution

1. Add Glide Library for Image Loading

To simplify the image loading process, we will use the popular Glide library. Glide is known for its efficiency in processing large images and reducing memory usage.

Gradle Dependency

Add the following lines to your build.gradle file:

2. Create a POJO Class

You will need a Plain Old Java Object (POJO) to hold the information for the film, including its ID and name.

3. Create a Custom Adapter

The custom adapter is responsible for creating list items dynamically based on the data provided.

4. Populate the ListView

Finally, you can set up your ListView by initializing it with the custom adapter you've created and populating it with data retrieved from the API.

Conclusion

By following the above steps, you have successfully created a ListView that displays images downloaded from an API alongside text. Utilizing Glide for image loading not only improves performance but also ensures that your application handles different image sizes efficiently. With a clear understanding of custom adapters and the use of efficient libraries, you can greatly enhance the functionality and appearance of your Android applications.

Now you're ready to build a visually appealing and functional ListView for your project!
