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
? Examples	final char	charAt(int i) Returns the character at the specified index, with the first character having index zero.
? Examples	final void	getChars(int start, int end, char[] dest, int off) Exactly like String.getChars(): copy chars `start` through `end - 1` from this CharSequence into `dest` beginning at offset `destoff`.
? Examples	int	getSpanEnd( Object what) Return the end of the range of text to which the specified markup object is attached, or -1 if the object is not attached.
? Examples	int	getSpanFlags( Object what) Return the flags that were specified when `setSpan(Object, int, int, int)` was used to attach the specified markup object, or 0 if the specified object has not been attached.
? Examples	int	getSpanStart( Object what) Return the beginning of the range of text to which the specified markup object is attached, or -1 if the object is not attached.
? Examples	<T> T[]	getSpans(int queryStart, int queryEnd, Class<T> kind) 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.
? Examples	final int	length() Returns the number of characters in this sequence.
? Examples	int	nextSpanTransition(int start, int limit, Class kind) Return the first offset greater than or equal to `start` where a markup object of class `type` begins or ends, or `limit` if there are no starts or ends greater than or equal to `start` but less than `limit`.
? Examples	CharSequence	subSequence(int start, int end) Returns a `CharSequence` from the `start` index (inclusive) to the `end` index (exclusive) of this sequence.
? Examples	final String	toString() Returns a string containing a concise, human-readable description of this object.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals( Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Invoked when the garbage collector has detected that this instance is no longer reachable.
final Class<?>	getClass() Returns the unique instance of `Class` that represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.

From interface android.text.GetChars

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 `setSpan(Object, int, int, int)` 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 type) Return the first offset greater than or equal to `start` where a markup object of class `type` begins or ends, or `limit` if there are no starts or ends greater than or equal to `start` but less than `limit`.

From interface java.lang.CharSequence

Public Constructors

public SpannedString (CharSequence source)

Added in API level 1

Public Methods

public final char charAt (int i)

Added in API level 1

Returns the character at the specified index, with the first character having index zero.

Parameters

i	the index of the character to return.

Returns

the requested character.

public final void getChars (int start, int end, char[] dest, int off)

Added in API level 1

Exactly like String.getChars(): copy chars start through end - 1 from this CharSequence into dest beginning at offset destoff.

public int getSpanEnd (Object what)

Added in API level 1

Return the end of the range of text to which the specified markup object is attached, or -1 if the object is not attached.

public int getSpanFlags (Object what)

Added in API level 1

Return the flags that were specified when setSpan(Object, int, int, int) was used to attach the specified markup object, or 0 if the specified object has not been attached.

public int getSpanStart (Object what)

Added in API level 1

Return the beginning of the range of text to which the specified markup object is attached, or -1 if the object is not attached.

public T[] getSpans (int queryStart, int queryEnd, Class<T> kind)

Added in API level 1

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. Specify Object.class for the type if you want all the objects regardless of type.

public final int length ()

Added in API level 1

Returns the number of characters in this sequence.

Returns

the number of characters.

public int nextSpanTransition (int start, int limit, Class kind)

Added in API level 1

Return the first offset greater than or equal to start where a markup object of class type begins or ends, or limit if there are no starts or ends greater than or equal to start but less than limit. Specify null or Object.class for the type if you want every transition regardless of type.

public CharSequence subSequence (int start, int end)

Added in API level 1

Returns a CharSequence from the start index (inclusive) to the end index (exclusive) of this sequence.

Parameters

start	the start offset of the sub-sequence. It is inclusive, that is, the index of the first character that is included in the sub-sequence.
end	the end offset of the sub-sequence. It is exclusive, that is, the index of the first character after those that are included in the sub-sequence

Returns

the requested sub-sequence.

public final String toString ()

Added in API level 1

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Returns

a printable representation of this object.

public static SpannedString valueOf (CharSequence source)

Added in API level 1
