Solving Image Display Issues in Android RecyclerView with Volley

Are you encountering a frustrating problem where your images are not displaying in a new activity when using a RecyclerView and Volley in your Android application? You are not alone! Many developers face this issue, especially when they need to pass image data from one activity to another. In this guide, we will explore the problem and provide a clear, step-by-step solution to get your images loading correctly in your new activity.

The Problem

When trying to display images and text in a new activity after clicking on an item in a RecyclerView, it’s common to see only the text displayed, while the images fail to load. In many cases, this is due to how the image data is being passed to the new activity and how the image is being set in that activity.

Example Code Overview

The implementation involves three main components of your Android app:

MyAdaptor.java: Handles the RecyclerView adapter and item click events.

DetailsActivity.java: Displays the selected item's details, including the image and text.

DisplayUser.java: A helper class that holds user data.

What Went Wrong?

In your current setup within DetailsActivity, you have used this line of code to set the image resource:

This line is likely incorrect as it attempts to retrieve the image as an integer resource ID, which doesn't match how images are handled from a network source.

The Solution

Here’s how you can correctly implement image loading using Glide in DetailsActivity:

Step 1: Modify DetailsActivity

Replace the problematic line of code in the onCreate method of DetailsActivity.java with the following:

Step 2: Code Breakdown

Using Glide: This line uses Glide to load the image from the URL constructed with the base URL and the image name passed via the intent.

getApplicationContext(): This ensures proper context is being used for loading the image.

String extra: By using getIntent().getStringExtra("imagename"), you can dynamically retrieve and construct the image URL that you need to load.

Step 3: Final DetailsActivity Code

Here’s how your revised DetailsActivity.java should look:

Conclusion

By following these steps, you should be able to display both images and text in your new activity without issues. Always ensure that you are passing the correct data types and properly using libraries like Glide to handle image loading from URLs.
