Note that if you set an image via ImageView.setImageBitmap(BITMAP)it internally creates a new BitmapDrawableeven if you pass null. In that case the check imageViewOne.getDrawable() == nullis false anytime. To get to know if an image is set you can do the following:

private boolean hasImage(@NonNull ImageView view) {
     Drawable drawable = view.getDrawable();
     boolean hasImage = (drawable != null);

     if (hasImage && (drawable instanceof BitmapDrawable)) {
         hasImage = ((BitmapDrawable)drawable).getBitmap() != null;
     }

     return hasImage;
}
