Setup a RichContentView

Add a RichContentView to an xml layout, wrap around a ScrollView to enable content scrolling.

 <ScrollView
     :layout_width="match_parent"
     android:layout_height="match_parent">
     <io.square1.richtextlib.ui.RichContentView
         android:padding="10dip"
         android:id="@+id/richTextView"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:text="@string/hello_blank_fragment" />
 </ScrollView>

Enable Image download

Supply an instance of a class that implements UrlImageDownloader instance and can download images from the network:

       contentView.setUrlBitmapDownloader(new UrlBitmapDownloader() {

            @Override
            public void downloadImage(RemoteBitmapSpan urlBitmapSpan, Uri image) {
                    Glide.with(getActivity())
                            .load(image)
                            .diskCacheStrategy(DiskCacheStrategy.NONE)
                            .skipMemoryCache(true)
                            .into(new GlideTarget(getActivity(),urlBitmapSpan));
                }

        });

Enable click events

Supply an instance of a clicked observer to receive on click events on parts of the content:

        contentView.setOnSpanClickedObserver(new RichContentViewDisplay.OnSpanClickedObserver() {
            @Override
            public boolean onSpanClicked(ClickableSpan span) {
                String action = span.getAction();
                action = TextUtils.isEmpty(action) ? " no action" : action;
                Toast.makeText(getContext(), action, Toast.LENGTH_LONG).show();
                return true;
            }
        });

Parse and display of HTML

 String html = "<p><i>This text is italic</i></p>";
 RichTextDocumentElement element = RichTextV2.textFromHtml(context, html);
 contentView.setText(element);

Sample Fluent Interface to create formatted text

 String paragraph = getResources().getString(R.string.sample_text);
       RichTextDocumentElement element = new RichTextDocumentElement
                .TextBuilder("What is Lorem Ipsum")
                .bold()
                .color(Color.BLUE)
                .underline(true)
                .sizeChange(1.5f)
                .center()
                .newLine()
                .image("https://netdna.webdesignerdepot.com/uploads/01/07/icons-animation.gif",,10)
                .click("You have clicked on the image at the !")
                .newLine()
                .append("Click the Image above")
                .font("fonts/SourceCodePro-Bold.ttf")
                .center()
                .bold()
                .sizeChange(1.5f)
                .color(Color.RED)
                .newLine()
                .append(paragraph)
                .left()
                .image("http://random-ize.com/lorem-ipsum-generators/lorem-ipsum/lorem-ipsum.jpg")
                .click("You have clicked on the  image in the middle of the text")
                .append("Click the lorem ipsum image")
                .font("fonts/GreatVibes-Regular.otf")
                .center()
                .bold()
                .sizeChange(1.5f)
                .color(Color.RED)
                .newLine()
                .video("http://html5demos.com/assets/dizzy.mp4")
                .append("It has survived not only five centuries,")
                .color(Color.GRAY)
                .sizeChange(2.0f)
                .center()
                .append("but also the leap into electronic typesetting,")
                .strikethrough(true)
                .append("remaining essentially unchanged.")
                .click("Hello you have clicked on the text")
                .bold()
                .italic()
                .build();
