How to Create a Custom ListView from Two String Arrays in Fragment?

If you are working with Android and need to display a list of products, along with their prices, in a ListView, you may encounter some challenges. You might wonder how to bind two different ArrayList<String> to your ListView, so that each item displays the product name and its corresponding price. Fear not! In this guide, we will break down the solution step by step.

Understanding the Problem

The problem at hand is to create a ListView that shows both product names and their prices, fetched from two separate ArrayLists. Initially, you might try using two different ArrayAdapter instances, but you will find that only the last ArrayAdapter affects the display.

Example Code Snippet

Here is a simplified structure of your ShopFragment.java that you might start with:

In this code, you have two ArrayLists: name_of_product for product names and price_of_product for their prices.

Implementing the Solution

To effectively link both ArrayLists, you'll need to create a custom ArrayAdapter. Here's how you can do that:

Step 1: Update the ArrayAdapter

Instead of creating a standard ArrayAdapter, you will override its getView() method. This allows you to customize how each item is displayed in your ListView. Here’s the code that you should use to create your adapter:

Step 4: Handling Item Clicks

Keep your existing onItemClick method to manage what happens when a user selects a product. You can customize the response based on the selected item.

Conclusion

By following these steps, you can create a custom ListView that connects two separate ArrayLists in your Android application's Fragment. This technique not only cleans your code but also enhances the user experience by displaying relevant data together efficiently.

Now you're set to implement this on your own and display names and prices in a seamless list format! If you have any questions or need further assistance, feel free to reach out in the comments below.
