How to load an ImageView by URL in Android?

1. Picasso allows for hassle-free image loading in your application—often in one line of code!

Use Gradle:

implementation 'com.squareup.picasso:picasso:(insert latest version)'

Just one line of code!

Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);

2. Glide An image loading and caching library for Android focused on smooth scrolling

Use Gradle:

repositories {
   mavenCentral() 
   google()
}

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

// For a simple view:
Glide.with(this).load("http://i.imgur.com/DvpvklR.png").into(imageView);

3. fresco is a powerful system for displaying images on Android applications. Fresco takes care of image loading and display, so you don't have to.

Getting Started with Fresco

From Android developer:

// show The Image in a ImageView
new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
            .execute("http://java.sogeti.nl/JavaBlog/wp-content/uploads/2009/04/android_icon_256.png");

public void onClick(View v) {
    startActivity(new Intent(this, IndexActivity.class));
    finish();

}

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
    ImageView bmImage;

    public DownloadImageTask(ImageView bmImage) {
        this.bmImage = bmImage;
    }

    protected Bitmap doInBackground(String... urls) {
        String urldisplay = urls[0];
        Bitmap mIcon11 = null;
        try {
            InputStream in = new java.net.URL(urldisplay).openStream();
            mIcon11 = BitmapFactory.decodeStream(in);
        } catch (Exception e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return mIcon11;
    }

    protected void onPostExecute(Bitmap result) {
        bmImage.setImageBitmap(result);
    }
}
