How to Pull Genre Names from Movie Details in Android using Kotlin

In the world of Android app development, integrating third-party APIs can be a game-changer for your application. One common requirement is to fetch details about movies, including their genres, from APIs like The Movie Database (TMDB). If you’re wondering how to pull genre names from movie details and display them separately in a TextView, you’re in the right place!

The Problem: Fetching Genre Names

When working with the TMDB API, you might find yourself needing to display movie genres separately in your application's user interface. This is particularly useful for enhancing the user experience by providing clear and accessible information about the movie's categorization. Here's the structure from the MovieDetails data class that contains the genres:

The challenge lies in extracting these genre names efficiently after you've made a successful API call.

The Solution: Displaying Genre Names

There are several methods to display genre names based on your desired format. Below, I’ll outline two straightforward approaches for achieving this.

Method 1: Comma-Separated Genre Names

If you prefer to show the genre names in a single line separated by commas, you can use the following code snippet:

Explanation:

response?.body()?.genres: Accesses the list of genres from the movie details response.

map { it.name }: Creates a list of genre names from the list of Genre objects.

joinToString(", "): Joins the list into a single string, with each genre name separated by a comma and a space.

?: "": Ensures that if there are no genres, an empty string is displayed.

Method 2: New Line Formatted Genre Names

In case you want to display each genre on a new line, you can modify the approach as follows:

Explanation:

forEach: Iterates over each Genre object in the list.

tvGenres.append("${it.name}\n"): Appends the genre name followed by a newline character to the TextView. This will format your genre names as a list, making it visually distinct.

Conclusion

By leveraging the TMDB API and Kotlin's powerful features, you can effectively pull and display genre names in your Android application. Whether you choose a comma-separated format or a list format depends on your design preference. Remember, the clarity and accessibility of information can significantly enhance your app's user experience.
