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 spansIf 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) })
