interface UpdateLayout : UpdateAppearance

android.text.style.UpdateLayout

Known Direct Subclasses MetricAffectingSpan MetricAffectingSpan The classes that affect character-level text formatting in a way that changes the width or height of characters extend this class.

Known Indirect Subclasses AbsoluteSizeSpan, DynamicDrawableSpan, ImageSpan, LocaleSpan, RelativeSizeSpan, ReplacementSpan, ScaleXSpan, StyleSpan, SubscriptSpan, SuperscriptSpan, TextAppearanceSpan, TypefaceSpan AbsoluteSizeSpan A span that changes the size of the text it's attached to. DynamicDrawableSpan Span that replaces the text it's attached to with a Drawable that can be aligned with the bottom or with the baseline of the surrounding text. ImageSpan Span that replaces the text it's attached to with a Drawable that can be aligned with the bottom or with the baseline of the surrounding text. LocaleSpan Changes the Locale of the text to which the span is attached. RelativeSizeSpan Uniformly scales the size of the text to which it's attached by a certain proportion. ReplacementSpan ScaleXSpan Scales horizontally the size of the text to which it's attached by a certain factor. StyleSpan Span that allows setting the style of the text it's attached to. SubscriptSpan The span that moves the position of the text baseline lower. SuperscriptSpan The span that moves the position of the text baseline higher. TextAppearanceSpan Sets the text appearance using the given TextAppearance attributes. TypefaceSpan Span that updates the typeface of the text it's attached to.

The classes that affect character-level text formatting in a way that triggers a text layout update when one is added or removed must implement this interface. This interface also includes UpdateAppearance since such a change implicitly also impacts the appearance.
