StyleSpan

Kotlin |Java

open class StyleSpan : MetricAffectingSpan, ParcelableSpan

kotlin.Any
↳	android.text.style.CharacterStyle
	↳	android.text.style.MetricAffectingSpan
		↳	android.text.style.StyleSpan

Span that allows setting the style of the text it's attached to. Possible styles are: Typeface.NORMAL, Typeface.BOLD, Typeface.ITALIC and Typeface.BOLD_ITALIC.

Note that styles are cumulative -- if both bold and italic are set in separate spans, or if the base style is bold and a span calls for italic, you get bold italic. You can't turn off a style from the base style.

For example, the StyleSpan can be used like this:

SpannableString string = new SpannableString("Bold and italic text");
  string.setSpan(new StyleSpan(Typeface.BOLD), 0, 4, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
  string.setSpan(new StyleSpan(Typeface.ITALIC), 9, 15, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

Text styled bold and italic with the StyleSpan.

Inherited functions

From class MetricAffectingSpan

MetricAffectingSpan!

getUnderlying()

Returns "this" for most MetricAffectingSpans, but for MetricAffectingSpans that were generated by wrap, returns the underlying MetricAffectingSpan.

From class CharacterStyle

Unit

updateDrawState(tp: TextPaint!)

CharacterStyle!

wrap(cs: CharacterStyle!)

A given CharacterStyle can only applied to a single region of a given Spanned. If you need to attach the same CharacterStyle to multiple regions, you can use this method to wrap it with a new object that will have the same effect but be a distinct object so that it can also be attached without conflict.
