SpannedString

public final class SpannedString extends Object
implements CharSequence CharSequence GetChars Spanned

This is the class for text whose content and markup are immutable. For mutable markup, see SpannableString; for mutable text, see SpannableStringBuilder.

Inherited Constant Summary

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.

Parameters

source

Public Methods

public final char charAt (int i)

Returns the char value at the specified index. An index ranges from zero to length() - 1. The first char value of the sequence is at index zero, the next at index one, and so on, as for array indexing.

If the char value specified by the index is a surrogate, the surrogate value is returned.

Parameters

i	the index of the char value to be returned

Returns

• the specified char value

public boolean equals (Object o)

Parameters

o

public 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.

Parameters

start
end
dest
off

public 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.

Parameters

what

public 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.

Parameters

what

public 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.

Parameters

what

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

Parameters

queryStart
queryEnd
kind

public int hashCode ()

public final int length ()

Returns the length of this character sequence. The length is the number of 16-bit chars in the sequence.

Returns

• the number of chars in this sequence

public 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. Specify null or Object.class for the type if you want every transition regardless of type.

Parameters

start
limit
kind

public CharSequence subSequence (int start, int end)

Returns a new CharSequence that is a subsequence of this sequence. The subsequence starts with the char value at the specified index and ends with the char value at index end - 1. The length (in chars) of the returned sequence is end - start, so if start == end then an empty sequence is returned.

Parameters

start	the start index, inclusive
end	the end index, exclusive

Returns

• the specified subsequence

public final String toString ()

public static SpannedString valueOf (CharSequence source)

Parameters
