CAP_MODE_CHARACTERS

int CAP_MODE_CHARACTERS

Capitalization mode for getCapsMode(CharSequence, int, int): capitalize all characters. This value is explicitly defined to be the same as TYPE_TEXT_FLAG_CAP_CHARACTERS.

CHAR_SEQUENCE_CREATOR

Creator<CharSequence> CHAR_SEQUENCE_CREATOR

commaEllipsize

CharSequence commaEllipsize (CharSequence text, 
                TextPaint p, 
                float avail, 
                String oneMore, 
                String more)

This method was deprecated in API level O.
Do not use. This is not internationalized, and has known issues with right-to-left text, languages that have more than one plural form, languages that use a different character as a comma-like separator, etc. Use listEllipsize(Context, List, String, TextPaint, float, int) instead.

Converts a CharSequence of the comma-separated form "Andy, Bob, Charles, David" that is too wide to fit into the specified width into one like "Andy, Bob, 2 more".

concat

CharSequence concat (CharSequence... text)

Returns a CharSequence concatenating the specified CharSequences, retaining their spans if any. If there are no parameters, an empty string will be returned. If the number of parameters is exactly one, that parameter is returned as output, even if it is null. If the number of parameters is at least two, any null CharSequence among the parameters is treated as if it was the string "null". If there are paragraph spans in the source CharSequences that satisfy paragraph boundary requirements in the sources but would no longer satisfy them in the concatenated CharSequence, they may get extended in the resulting CharSequence or not retained.

copySpansFrom

void copySpansFrom (Spanned source, 
                int start, 
                int end, 
                Class kind, 
                Spannable dest, 
                int destoff)

Copies the spans from the region start...end in source to the region destoff...destoff+end-start in dest. Spans in source that begin before start or end after end but overlap this range are trimmed as if they began at start or ended at end.

dumpSpans

void dumpSpans (CharSequence cs, 
                Printer printer, 
                String prefix)

Debugging tool to print the spans in a CharSequence. The output will be printed one span per line. If the CharSequence is not a Spanned, then the entire string will be printed on a single line.

ellipsize

CharSequence ellipsize (CharSequence text, 
                TextPaint p, 
                float avail, 
                TextUtils.TruncateAt where)

Returns the original text if it fits in the specified width given the properties of the specified Paint, or, if it does not fit, a truncated copy with ellipsis character added at the specified edge or center.

ellipsize

CharSequence ellipsize (CharSequence text, 
                TextPaint paint, 
                float avail, 
                TextUtils.TruncateAt where, 
                boolean preserveLength, 
                TextUtils.EllipsizeCallback callback)

Returns the original text if it fits in the specified width given the properties of the specified Paint, or, if it does not fit, a copy with ellipsis character added at the specified edge or center. If preserveLength is specified, the returned copy will be padded with zero-width spaces to preserve the original length and offsets instead of truncating. If callback is non-null, it will be called to report the start and end of the ellipsized range. TextDirection is determined by the first strong directional character.

equals

boolean equals (CharSequence a, 
                CharSequence b)

Returns true if a and b are equal, including if they are both null.

Note: In platform versions 1.1 and earlier, this method only worked well if both the arguments were instances of String.

expandTemplate

CharSequence expandTemplate (CharSequence template, 
                CharSequence... values)

Replace instances of "^1", "^2", etc. in the template CharSequence with the corresponding values. "^^" is used to produce a single caret in the output. Only up to 9 replacement values are supported, "^10" will be produce the first replacement value followed by a '0'.

getCapsMode

int getCapsMode (CharSequence cs, 
                int off, 
                int reqModes)

Determine what caps mode should be in effect at the current offset in the text. Only the mode bits set in reqModes will be checked. Note that the caps mode flags here are explicitly defined to match those in InputType.

getChars

void getChars (CharSequence s, 
                int start, 
                int end, 
                char[] dest, 
                int destoff)

getLayoutDirectionFromLocale

int getLayoutDirectionFromLocale (Locale locale)

Return the layout direction for a given Locale

getOffsetAfter

int getOffsetAfter (CharSequence text, 
                int offset)

getOffsetBefore

int getOffsetBefore (CharSequence text, 
                int offset)

getReverse

CharSequence getReverse (CharSequence source, 
                int start, 
                int end)

This method was deprecated in API level 24.
Do not use.

This function only reverses individual chars and not their associated spans. It doesn't support surrogate pairs (that correspond to non-BMP code points), combining sequences or conjuncts either.

getTrimmedLength

int getTrimmedLength (CharSequence s)

Returns the length that the specified CharSequence would have if spaces and ASCII control characters were trimmed from the start and end, as by trim().

htmlEncode

String htmlEncode (String s)

Html-encode the string.

indexOf

int indexOf (CharSequence s, 
                char ch, 
                int start, 
                int end)

indexOf

int indexOf (CharSequence s, 
                CharSequence needle, 
                int start, 
                int end)

indexOf

int indexOf (CharSequence s, 
                CharSequence needle, 
                int start)

indexOf

int indexOf (CharSequence s, 
                CharSequence needle)

indexOf

int indexOf (CharSequence s, 
                char ch, 
                int start)

indexOf

int indexOf (CharSequence s, 
                char ch)

isDigitsOnly

boolean isDigitsOnly (CharSequence str)

Returns whether the given CharSequence contains only digits.

isEmpty

boolean isEmpty (CharSequence str)

Returns true if the string is null or 0-length.

isGraphic

boolean isGraphic (CharSequence str)

Returns whether the given CharSequence contains any printable characters.

isGraphic

boolean isGraphic (char c)

This method was deprecated in API level 24.
Use isGraphic(CharSequence) instead.

Returns whether this character is a printable character. This does not support non-BMP characters and should not be used.

join

String join (CharSequence delimiter, 
                Iterable tokens)

Returns a string containing the tokens joined by delimiters.

join

String join (CharSequence delimiter, 
                Object[] tokens)

Returns a string containing the tokens joined by delimiters.

lastIndexOf

int lastIndexOf (CharSequence s, 
                char ch, 
                int last)

lastIndexOf

int lastIndexOf (CharSequence s, 
                char ch)

lastIndexOf

int lastIndexOf (CharSequence s, 
                char ch, 
                int start, 
                int last)

regionMatches

boolean regionMatches (CharSequence one, 
                int toffset, 
                CharSequence two, 
                int ooffset, 
                int len)

replace

CharSequence replace (CharSequence template, 
                String[] sources, 
                CharSequence[] destinations)

Return a new CharSequence in which each of the source strings is replaced by the corresponding element of the destinations.

split

String[] split (String text, 
                Pattern pattern)

Splits a string on a pattern. String.split() returns [''] when the string to be split is empty. This returns []. This does not remove any empty strings from the result.

split

String[] split (String text, 
                String expression)

String.split() returns [''] when the string to be split is empty. This returns []. This does not remove any empty strings from the result. For example split("a,", "," ) returns {"a", ""}.

stringOrSpannedString

CharSequence stringOrSpannedString (CharSequence source)

substring

String substring (CharSequence source, 
                int start, 
                int end)

Create a new String object containing the given range of characters from the source string. This is different than simply calling CharSequence.subSequence in that it does not preserve any style runs in the source sequence, allowing a more efficient implementation.

writeToParcel

void writeToParcel (CharSequence cs, 
                Parcel p, 
                int parcelableFlags)

Flatten a CharSequence and whatever styles can be copied across processes into the parcel.
