Solving the Frustrating “Cannot resolve method ‘fromDrawable’ in ‘ImageHolder'” Error

Are you tired of staring at the cryptic error message “Cannot resolve method ‘fromDrawable’ in ‘ImageHolder'” and wondering what on earth it means? Well, wonder no more! This article is here to guide you through the troubleshooting process and provide clear, step-by-step instructions to get your code up and running smoothly.

What is the ‘fromDrawable’ method, anyway?

The ‘fromDrawable’ method is part of the Glide library, a popular image loading and caching library for Android. It’s used to load images from a Drawable resource into an ImageHolder, which is a component that displays images in your app. Sounds simple, right? But sometimes, things can get complicated, and that’s when the error message strikes.

The Error Message Explained

So, what does the error message “Cannot resolve method ‘fromDrawable’ in ‘ImageHolder'” actually mean? It’s telling you that the compiler can’t find the ‘fromDrawable’ method in the ImageHolder class. This can happen for a few reasons:

• The ‘fromDrawable’ method doesn’t exist in the ImageHolder class.
• The method is private or protected, and you’re trying to access it from outside the class.
• You’re using an outdated or incompatible version of the Glide library.

Troubleshooting Steps

Don’t panic! We’ve got this. Let’s go through some troubleshooting steps to resolve the issue:

Step 1: Check Your Glide Version

Make sure you’re using a compatible version of Glide. You can check the version by looking at your build.gradle file:

dependencies {
  implementation 'com.github.bumptech.glide:glide:4.11.0'
}

If you’re using an older version, update to the latest one:

dependencies {
  implementation 'com.github.bumptech.glide:glide:4.12.0'
}

Step 2: Verify ImageHolder Class

Double-check that you’re importing the correct ImageHolder class. Make sure it’s not a custom class with a similar name:

import com.bumptech.glide.request.target.Target;
import com.bumptech.glide.request.target.ImageViewTarget;

public class ImageHolder extends ImageViewTarget<ImageView> {
  // your code here
}

Step 3: Check Method Visibility

Ensure that the ‘fromDrawable’ method is public and accessible:

public class ImageHolder extends ImageViewTarget<ImageView> {
  public void fromDrawable(Drawable drawable) {
    // method implementation
  }
}

Step 4: Clean and Rebuild Your Project

Sometimes, a simple clean and rebuild can resolve the issue. Try it out:

gradle clean build

Step 5: Check for Conflicting Libraries

If you’re using other libraries that interact with Glide, such as Picasso or Fresco, try removing them or updating to the latest version:

dependencies {
  implementation 'com.squareup.picasso:picasso:2.71828'
  implementation 'com.facebook.fresco:fresco:2.5.0'
}

Example Code to Get You Started

Here’s a working example of using the ‘fromDrawable’ method with Glide:

import android.widget.ImageView;
import com.bumptech.glide.Glide;
import com.bumptech.glide.request.target.Target;

public class ImageHolder extends ImageViewTarget<ImageView> {
  private ImageView imageView;

  public ImageHolder(ImageView imageView) {
    this.imageView = imageView;
  }

  public void fromDrawable(Drawable drawable) {
    Glide.with(imageView.getContext())
        .load(drawable)
        .into(imageView);
  }
}

Conclusion

And that’s it! With these troubleshooting steps and explanations, you should be able to resolve the “Cannot resolve method ‘fromDrawable’ in ‘ImageHolder'” error and get your image loading and caching working smoothly. Remember to always check your Glide version, method visibility, and library conflicts. Happy coding!
