Sample

TextView textView = (TextView) findViewById(R.id.text);
textView.setMovementMethod(LinkMovementMethod.getInstance());
String sample = "<h2>Hello wold</h2>"
                 + "<font size=\"5\" color=\"#FF0000\">Font size</font>"
                 + "<img src=\"http://www.sample.com\"/>";
HtmlText.from(sample)
    .setImageLoader(new HtmlImageLoader() {
        @Override
        public void loadImage(String url, final Callback callback) {
            // Glide sample, you can also use other image loader
            Glide.with(context)
                 .load(url)
                 .asBitmap()
                 .into(new SimpleTarget<Bitmap>() {
                     @Override
                     public void onResourceReady(Bitmap resource,
                                                 GlideAnimation<? super Bitmap> glideAnimation) {
                         callback.onLoadComplete(resource);
                     }

                     @Override
                     public void onLoadFailed(Exception e, Drawable errorDrawable) {
                         callback.onLoadFailed();
                     }
                 });
        }

        @Override
        public Drawable getDefaultDrawable() {
            return ContextCompat.getDrawable(context, R.drawable.image_placeholder_loading);
        }

        @Override
        public Drawable getErrorDrawable() {
            return ContextCompat.getDrawable(context, R.drawable.image_placeholder_fail);
        }

        @Override
        public int getMaxWidth() {
            return getTextWidth();
        }

        @Override
        public boolean fitWidth() {
            return false;
        }
    })
    .setOnTagClickListener(new OnTagClickListener() {
        @Override
        public void onImageClick(Context context, List<String> imageUrlList, int position) {
            // image click
        }

        @Override
        public void onLinkClick(Context context, String url) {
            // link click
        }
    })
    .into(textView);
