StyleSpan
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);
