TagHandler

Is notified when HTML tags are encountered that the parser does not know how to interpret.

InputFilter

InputFilters can be attached to Editables to constrain the changes that can be made to them.

InputType

ParcelableSpan

A special kind of Parcelable for objects that will serve as text spans.

Spannable

This is the interface for text to which markup objects can be attached and detached.

Spanned

This is the interface for text that has markup objects attached to ranges of it.

SpanWatcher

When an object of this type is attached to a Spannable, its methods will be called to notify it that other markup objects have been added, changed, or removed.

TextDirectionHeuristic

Interface for objects that use a heuristic for guessing at the paragraph direction by examining text.

GlyphsConsumer

A consumer interface for accepting text shape result.

EllipsizeCallback

StringSplitter

SpannedString

This is the class for text whose content and markup are immutable.
