Android Arsenal Build Status Javadoc

This lib provides simple and fluent API for creating Android Spannable. Features:

  • Simple and fluent API
  • Helpers to create spans
  • Small method footprint (<200 methods, 29kb AAR package)

This library focuses on building spannable. If you prefer put full text first and then apply spans, take a look at another awesome library

Examples:

Spannable spannable = new Spanner()
        .append("Original text\n\n")
        .append("Big and blurry\n", Spans.sizePX(100))
        .span("blurry", blur(5.0f, BlurMaskFilter.Blur.SOLID))
        .append("big in DP\n", sizeDP(30))
        .append("50% of original size\n", scaleSize(0.5f))
        .append("bold\n", bold())
        .append("italic\n", italic())
        .append("bold and italic\n", boldItalic())
        .append("custom typeface\n", font("sans-serif-black"))
        .append("strike through\n", strikeThrough())
        .append("underline\n", underline())
        .append("background\n", background(Color.YELLOW))
        .append("foreground\n", foreground(Color.RED))
        .append("subscript\n", subscript())
        .append("superscript\n", superscript())
        .append(image(context, R.drawable.ic_android_16dp)).append("\n")
        .append("quite\n", quote())
        .append("The quick brown fox jumps over the lazy dog\n", bold(), foreground(0xFF904f1c), Spans.quote())
        .append("Custom\n", custom(new CustomSpan()))
        .append("Click here\n", click(onClickListener))
        .append("http://www.android.com\n", url("http://www.android.com"))
        ;

It looks like:

You can manipulate text in many more ways:

Spannable spannable = new Spanner("The quick brown fox jumps over the lazy dog")
        .span("fox", foreground(Color.RED)) // search and span by given text
        .replace("dog", "cat", strikeThrough()) // any number of spans
        .insert(5, "foo", bold(), italic()) // any number of spans
        .append("bar", underline()); // any number of spans

If you need custom span, you need span builder:

//java 7
Spannable spannable = new Spanner("The quick brown fox jumps over the lazy dog")
        .span("fox", custom(new SpanBuilder() {
                 @Override
                 public Object build() {
                     return new StyleSpan(Typeface.ITALIC);
                 }
             });
             
//java 8
Spannable spannable = new Spanner("The quick brown fox jumps over the lazy dog")
        .span("fox", custom(() -> new StyleSpan(Typeface.ITALIC));
        
//kotlin
val spannable = Spanner("The quick brown fox jumps over the lazy dog")
        .span("fox", custom { StyleSpan(Typeface.ITALIC) })

Reference

Spans:

sizePX(int) background(int color) center()
sizeDP(int) foreground(int color) alignmentOpposite()
sizeSP(int) subscript() alignmentNormal()
scaleSize(float) superscript() bullet(...)
bold() image(...) imageMargin(...)
italic() click(listener) leadingMargin(...)
boldItalic() url(url) edit(...)
font(String) custom(spanBuilder) emboss(...)
strikeThrough() quote() blur(...)
underline() appearance(...) locale(...)
tabStop(where) suggestion(...) lineBackground(color)
lineHeight(height)
