    Use Glide(https://github.com/bumptech/glide):

    GlideDrawableImageViewTarget imageViewTarget = new GlideDrawableImageViewTarget(imageview);
    
            Glide.with(this).load(R.raw.mygif).into(imageViewTarget);

    Glide is the best solution ever. Simply use this code

    String gifUrl = "http://part/to/your/gifFile.gif";
    Glide  
    .with( context )
    .load( gifUrl )
    .into( imageViewGif );

    Or you can simply add WebView to your xml and load the gif image inside the webview. You donot need to do anything else. The image will loop automatically inside the webview

    Put your .gif file into res/raw folder, in your fragment or activity and than you can set gif in imageview like

    GifAnimationDrawable gif;
    
        try {
                gif = new 
                 GifAnimationDrawable(getResources().openRawResource(R.raw.download));
                gif.setOneShot(false);
            } catch (NotFoundException e) {
                e.printStackTrace();
            } catch (IOException e) {
                e.printStackTrace();
            }
    
            ivGif.setImageDrawable(gif);
            gif.setVisible(true, true);
        }

    you can download the class from https://github.com/Hipmob/gifanimateddrawable/blob/master/src/com/hipmob/gifanimationdrawable/GifAnimationDrawable.java 404 Not Found https://gist.github.com/devunwired/4479231 404 Not Found

    If the any above link is not open you can find the class from below link

    hope this will save someones time lot because i admire from https://stackoverflow.com/a/11736861/3514144 but i want to show it in imageview

    As well if link is unavailable you can find class from Github too.Also if you found any problem leave a comment to this answer i'll try best to help :)

    Edit: 12-12-2019

    Another way to load gif in custom imageview use this library

    You should have a look at the Fresco library.

    Best and easiest solution to display GIF image in Android and it will work perfectly:

    • Open build.gradle (Module: app)
    • put in dependencies: compile 'pl.droidsonroids.gif:android-gif-drawable:1.1.+'
    • Open layout folder and put this code where you want to display GIF image: e-g activity_main.xml

       <pl.droidsonroids.gif.GifImageView
            android:layout_width="150dp"
            android:layout_height="wrap_content"
            android:src="@drawable/your_gif_file_name"/>
      
    • android:src="@drawable/your_gif_file_name", Replace 'your_gif_file_name' with your desired gif image file
