Spannable

Kotlin |Java

public interface Spannable
implements Spanned

android.text.Spannable

Known indirect subclasses Editable, PrecomputedText, SpannableString, SpannableStringBuilder Editable This is the interface for text whose content and markup can be changed (as opposed to immutable text like Strings).  PrecomputedText A text which has the character metrics data.  SpannableString This is the class for text whose content is immutable but to which markup objects can be attached and detached.  SpannableStringBuilder This is the class for text whose content and markup can both be changed.

---

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.

Summary

Nested classes
class	Spannable.Factory Factory used by TextView to create new Spannables.

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_EXCLUSIVE_INCLUSIVE 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.

Inherited methods
From interface android.text.Spanned abstract int getSpanEnd(Object tag) Return the end of the range of text to which the specified markup object is attached, or -1 if the object is not attached. abstract int getSpanFlags(Object tag) Return the flags that were specified when Spannable.setSpan was used to attach the specified markup object, or 0 if the specified object has not been attached. abstract int getSpanStart(Object tag) Return the beginning of the range of text to which the specified markup object is attached, or -1 if the object is not attached. abstract <T> T[] getSpans(int start, int end, Class<T> type) Return an array of the markup objects attached to the specified slice of this CharSequence and whose type is the specified type or a subclass of it. abstract int nextSpanTransition(int start, int limit, Class<T> type) Return the first offset greater than start where a markup object of class type begins or ends, or limit if there are no starts or ends greater than start but less than limit.
From interface java.lang.CharSequence abstract char charAt(int index) Returns the char value at the specified index. default IntStream chars() Returns a stream of int zero-extending the char values from this sequence. default IntStream codePoints() Returns a stream of code point values from this sequence. static int compare(CharSequence cs1, CharSequence cs2) Compares two CharSequence instances lexicographically. default boolean isEmpty() Returns true if this character sequence is empty. abstract int length() Returns the length of this character sequence. abstract CharSequence subSequence(int start, int end) Returns a CharSequence that is a subsequence of this sequence. abstract String toString() Returns a string containing the characters in this sequence in the same order as this sequence.

Public methods

removeSpan

Added in API level 1

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.

Parameters
what	Object

setSpan

Added in API level 1

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.

Parameters
what	Object
start	int
end	int
flags	int
