Spanny

A helper class that extends SpannableStringBuilder and adds methods to easily mark the text with multiple spans.

example

Download

You can just copy the class to your project or grab it via Gradle:

compile 'com.binaryfork:spanny:1.0.4'

Usage

Use .append(text, span) to add and mark the text with any span:

Spanny spanny = new Spanny("Underline text", new UnderlineSpan())
                .append("\nRed text", new ForegroundColorSpan(Color.RED))
                .append("\nPlain text");
textView.setText(spanny);

Mark the text with multiple spans:

spanny.append("Blue underlined text", new ForegroundColorSpan(Color.BLUE), new UnderlineSpan());

If you need a single SpannableString you can use a static method .spanText:

textView.setText(Spanny.spanText("Underline text", new UnderlineSpan()));

Find and span multiple appearences of a string:

Spanny spanny = new Spanny("All 'a' will be red.")
spanny.findAndSpan("a", new Spanny.GetSpan() {
            @Override public Object getSpan() {
                return new ForegroundColorSpan(Color.RED);
            }
        });

Example

Check the sample app for custom spannables.

You can easily make a text with over 20 styles in a single TextView:

Spanny spanny = new Spanny("StyleSpan", new StyleSpan(Typeface.BOLD_ITALIC))
                .append("CustomTypefaceSpan", new CustomTypefaceSpan(typeface))
                .append("CustomAlignmentSpan", new CustomAlignmentSpan(CustomAlignmentSpan.RIGHT_TOP))
                .append("\nUnderlineSpan, ", new UnderlineSpan())
                .append(" TypefaceSpan, ", new TypefaceSpan("serif"))
                .append("URLSpan, ", new URLSpan("google.com"))
                .append("StrikethroughSpan", new StrikethroughSpan())
                .append("\nQuoteSpan", new QuoteSpan(Color.RED))
                .append("\nPlain text")
                .append("SubscriptSpan", new SubscriptSpan())
                .append("SuperscriptSpan", new SuperscriptSpan())
                .append("\n\nBackgroundSpan", new BackgroundColorSpan(Color.LTGRAY))
                .append("\n\nCustomBackgroundSpan", new CustomBackgroundSpan(Color.DKGRAY, dp(16)))
                .append("\n\nForegroundColorSpan", new ForegroundColorSpan(Color.LTGRAY))
                .append("\nAlignmentSpan", new AlignmentSpan.Standard(Layout.Alignment.ALIGN_CENTER))
                .append("\nTextAppearanceSpan\n", new TextAppearanceSpan(this, android.R.style.TextAppearance_Medium))
                .append("ImageSpan", new ImageSpan(getApplicationContext(), R.mipmap.ic_launcher))
                .append("\nRelativeSizeSpan", new RelativeSizeSpan(1.5f))
                .append("\n\nMultiple spans", new StyleSpan(Typeface.ITALIC), new UnderlineSpan(),
                        new TextAppearanceSpan(this, android.R.style.TextAppearance_Large),
                        new AlignmentSpan.Standard(Layout.Alignment.ALIGN_CENTER), new BackgroundColorSpan(Color.LTGRAY));
        textView.setText(spanny);
