Spannable

implements Spanned

android.text.Spannable

Known Indirect Subclasses

Editable, SpannableString, SpannableStringBuilder

Class Overview

This is the interface for text to which markup objects can be attached and detached. Not all Spannable classes have mutable text; see Editable for that.

Inherited Constants

From interface android.text.Spanned

int	SPAN_COMPOSING	This flag is set on spans that are being used to apply temporary styling information on the composing text of an input method, so that they can be found and removed when the composing text is being replaced.
int	SPAN_EXCLUSIVE_EXCLUSIVE	Spans of type SPAN_EXCLUSIVE_EXCLUSIVE do not expand to include text inserted at either their starting or ending point.
int	SPAN_EXCLUSIVE_INCLUSIVE	Non-0-length spans of type SPAN_INCLUSIVE_EXCLUSIVE expand to include text inserted at their ending point but not at their starting point.
int	SPAN_INCLUSIVE_EXCLUSIVE	Non-0-length spans of type SPAN_INCLUSIVE_EXCLUSIVE expand to include text inserted at their starting point but not at their ending point.
int	SPAN_INCLUSIVE_INCLUSIVE	Spans of type SPAN_INCLUSIVE_INCLUSIVE expand to include text inserted at either their starting or ending point.
int	SPAN_INTERMEDIATE	This flag will be set for intermediate span changes, meaning there is guaranteed to be another change following it.
int	SPAN_MARK_MARK	0-length spans with type SPAN_MARK_MARK behave like text marks: they remain at their original offset when text is inserted at that offset.
int	SPAN_MARK_POINT	SPAN_MARK_POINT is a synonym for SPAN_INCLUSIVE_INCLUSIVE.
int	SPAN_PARAGRAPH	SPAN_PARAGRAPH behaves like SPAN_INCLUSIVE_EXCLUSIVE (SPAN_MARK_MARK), except that if either end of the span is at the end of the buffer, that end behaves like _POINT instead (so SPAN_INCLUSIVE_INCLUSIVE if it starts in the middle and ends at the end, or SPAN_EXCLUSIVE_INCLUSIVE if it both starts and ends at the end).
int	SPAN_POINT_MARK	SPAN_POINT_MARK is a synonym for SPAN_EXCLUSIVE_EXCLUSIVE.
int	SPAN_POINT_MARK_MASK	Bitmask of bits that are relevent for controlling point/mark behavior of spans.
int	SPAN_POINT_POINT	0-length spans with type SPAN_POINT_POINT behave like cursors: they are pushed forward by the length of the insertion when text is inserted at their offset.
int	SPAN_PRIORITY	The bits specified by the SPAN_PRIORITY bitmap determine the order of change notifications -- higher numbers go first.
int	SPAN_PRIORITY_SHIFT	The bits numbered just above SPAN_PRIORITY_SHIFT determine the order of change notifications -- higher numbers go first.
int	SPAN_USER	The bits specified by the SPAN_USER bitfield are available for callers to use to store scalar data associated with their span object.
int	SPAN_USER_SHIFT	The bits numbered SPAN_USER_SHIFT and above are available for callers to use to store scalar data associated with their span object.

Public Methods
abstract void	removeSpan(Object what) Remove the specified object from the range of text to which it was attached, if any.
abstract void	setSpan(Object what, int start, int end, int flags) Attach the specified markup object to the range `start…end` of the text, or move the object to that range if it was already attached elsewhere.

Public Methods

public abstract void removeSpan (Object what)

Remove the specified object from the range of text to which it was attached, if any. It is OK to remove an object that was never attached in the first place.

public abstract void setSpan (Object what, int start, int end, int flags)

Attach the specified markup object to the range start…end of the text, or move the object to that range if it was already attached elsewhere. See Spanned for an explanation of what the flags mean. The object can be one that has meaning only within your application, or it can be one that the text system will use to affect text display or behavior. Some noteworthy ones are the subclasses of CharacterStyle and ParagraphStyle, and TextWatcher and SpanWatcher.
