FAKE_BOLD_TEXT_FLAG

Added in API level 1
public static final int FAKE_BOLD_TEXT_FLAG

Paint flag that applies a synthetic bolding effect to drawn text.

Enabling this flag will cause text draw operations to apply a simulated bold effect when drawing a Typeface that is not already bold.

Constant Value: 32 (0x00000020)

FILTER_BITMAP_FLAG

Added in API level 1
public static final int FILTER_BITMAP_FLAG

Paint flag that enables bilinear sampling on scaled bitmaps.

If cleared, scaled bitmaps will be drawn with nearest neighbor sampling, likely resulting in artifacts. This should generally be on when drawing bitmaps, unless performance-bound (rendering to software canvas) or preferring pixelation artifacts to blurriness when scaling significantly.

If bitmaps are scaled for device density at creation time (as resource bitmaps often are) the filtering will already have been done.

On devices running Build.VERSION_CODES#O and below, hardware accelerated drawing always uses bilinear sampling on scaled bitmaps, regardless of this flag. On devices running Build.VERSION_CODES#Q and above, this flag defaults to being set on a new Paint. It can be cleared with setFlags(int) or setFilterBitmap(boolean).

Constant Value: 2 (0x00000002)

HINTING_OFF

Added in API level 14
public static final int HINTING_OFF

public static final int HINTING_ON

Font hinter option that enables font hinting.

See also:

Constant Value: 1 (0x00000001)

LINEAR_TEXT_FLAG

Added in API level 1
public static final int LINEAR_TEXT_FLAG

Paint flag that enables smooth linear scaling of text.

Enabling this flag does not actually scale text, but rather adjusts text draw operations to deal gracefully with smooth adjustment of scale. When this flag is enabled, font hinting is disabled to prevent shape deformation between scale factors, and glyph caching is disabled due to the large number of glyph images that will be generated.

SUBPIXEL_TEXT_FLAG should be used in conjunction with this flag to prevent glyph positions from snapping to whole pixel values as scale factor is adjusted.

Constant Value: 64 (0x00000040)

START_HYPHEN_EDIT_INSERT_HYPHEN

Added in API level 29
public static final int START_HYPHEN_EDIT_INSERT_HYPHEN

An integer representing the starting of the line has normal hyphen character (U+002D).

Constant Value: 1 (0x00000001)

START_HYPHEN_EDIT_INSERT_ZWJ

Added in API level 29
public static final int START_HYPHEN_EDIT_INSERT_ZWJ

Constant Value: 2 (0x00000002)

START_HYPHEN_EDIT_NO_EDIT

Added in API level 29
public static final int START_HYPHEN_EDIT_NO_EDIT

An integer representing the starting of the line has no modification for hyphenation.

Constant Value: 0 (0x00000000)

STRIKE_THRU_TEXT_FLAG

Added in API level 1
public static final int STRIKE_THRU_TEXT_FLAG

Paint flag that applies a strike-through decoration to drawn text.

Constant Value: 16 (0x00000010)

SUBPIXEL_TEXT_FLAG

Added in API level 1
public static final int SUBPIXEL_TEXT_FLAG

Paint flag that enables subpixel positioning of text.

Enabling this flag causes glyph advances to be computed with subpixel accuracy.

This can be used with LINEAR_TEXT_FLAG to prevent text from jittering during smooth scale transitions.

Constant Value: 128 (0x00000080)

UNDERLINE_TEXT_FLAG

Added in API level 1
public static final int UNDERLINE_TEXT_FLAG

Paint flag that applies an underline decoration to drawn text.

Constant Value: 8 (0x00000008)

                int contextEnd, 
                boolean isRtl, 
                float advance)

Get the character offset within the string whose position is closest to the specified horizontal position.

The returned value is generally the value of offset for which getRunAdvance(char, int, int, int, int, boolean, int) yields a result most closely approximating advance, and which is also on a grapheme cluster boundary. As such, it is the preferred method for positioning a cursor in response to a touch or pointer event. The grapheme cluster boundaries are based on Unicode Standard Annex #29 but with some tailoring for better user experience.

Note that advance is a (generally positive) width measurement relative to the start of the run. Thus, for RTL runs it the distance from the point to the right edge.

All indices are relative to the start of text. Further, 0 <= contextStart <= start <= end <= contextEnd <= text.length must hold on entry, and start <= result <= end will hold on return.

Parameters
text char: the text to measure. Cannot be null.

start int: the index of the start of the range to measure

end int: the index + 1 of the end of the range to measure

contextStart int: the index of the start of the shaping context

contextEnd int: the index + 1 of the end of the range to measure

isRtl boolean: whether the run is in RTL direction

advance float: width relative to start of run

Returns
int index of offset

                int contextEnd, 
                boolean isRtl, 
                float advance)

Parameters
text CharSequence: the text to measure. Cannot be null.

start int: the index of the start of the range to measure

end int: the index + 1 of the end of the range to measure

contextStart int: the index of the start of the shaping context

getRunAdvance

Added in API level 23
public float getRunAdvance (char[] text, 
                int start, 
                int end, 
                int contextStart, 
                int contextEnd, 
                boolean isRtl, 
                int offset)

Measure cursor position within a run of text.

The run of text includes the characters from start to end in the text. In addition, the range contextStart to contextEnd is used as context for the purpose of complex text shaping, such as Arabic text potentially shaped differently based on the text next to it.

All text outside the range contextStart..contextEnd is ignored. The text between start and end will be laid out to be measured.

The returned width measurement is the advance from start to offset. It is generally a positive value, no matter the direction of the run. If offset == end, the return value is simply the width of the whole run from start to end.

Ligatures are formed for characters in the range start..end (but not for start..contextStart or end..contextEnd). If offset points to a character in the middle of such a formed ligature, but at a grapheme cluster boundary, the return value will also reflect an advance in the middle of the ligature. See getOffsetForAdvance(char, int, int, int, int, boolean, float) for more discussion of grapheme cluster boundaries.

The direction of the run is explicitly specified by isRtl. Thus, this method is suitable only for runs of a single direction.

All indices are relative to the start of text. Further, 0 <= contextStart <= start <= offset <= end <= contextEnd <= text.length must hold on entry.

Parameters
text char: the text to measure. Cannot be null.

start int: the index of the start of the range to measure

end int: the index + 1 of the end of the range to measure

contextStart int: the index of the start of the shaping context

contextEnd int: the index + 1 of the end of the shaping context

isRtl boolean: whether the run is in RTL direction

offset int: index of caret position

Returns
float width measurement between start and offset

                boolean isRtl, 
                float[] advances, 
                int advancesIndex)

Retrieve the character advances of the text. Returns the total advance width for the characters in the run from index for count of chars, and if advances is not null, the advance assigned to each of these characters (java chars).

The trailing surrogate in a valid surrogate pair is assigned an advance of 0. Thus the number of returned advances is always equal to count, not to the number of unicode codepoints represented by the run.

In the case of conjuncts or combining marks, the total advance is assigned to the first logical character, and the following characters are assigned an advance of 0.

This generates the sum of the advances of glyphs for characters in a reordered cluster as the width of the first logical character in the cluster, and 0 for the widths of all other characters in the cluster. In effect, such clusters are treated like conjuncts.

The shaping bounds limit the amount of context available outside start and end that can be used for shaping analysis. These bounds typically reflect changes in bidi level or font metrics across which shaping does not occur.

Parameters
chars char: the text to measure. This value cannot be null.

index int: the index of the first character to measure Value is 0 or greater

count int: the number of characters to measure Value is 0 or greater

contextIndex int: the index of the first character to use for shaping context. Context must cover the measureing target. Value is 0 or greater

contextCount int: the number of character to use for shaping context. Context must cover the measureing target. Value is 0 or greater

isRtl boolean: whether the run is in RTL direction

advances float: array to receive the advances, must have room for all advances. This can be null if only total advance is needed

advancesIndex int: the position in advances at which to put the advance corresponding to the character at start Value is 0 or greater

Returns
float the total advance in pixels

getTextRunCursor

Added in API level 29
public int getTextRunCursor (CharSequence text, 
                int contextStart, 
                int contextEnd, 
                boolean isRtl, 
                int offset, 
                int cursorOpt)

Returns the next cursor position in the run. This avoids placing the cursor between surrogates, between characters that form conjuncts, between base characters and combining marks, or within a reordering cluster.

ContextStart, contextEnd, and offset are relative to the start of text. The context is the shaping context for cursor movement, generally the bounds of the metric span enclosing the cursor in the direction of movement.

If cursorOpt is CURSOR_AT and the offset is not a valid cursor position, this returns -1. Otherwise this will never return a value before contextStart or after contextEnd.

Parameters

setTextLocale

Added in API level 17
public void setTextLocale (Locale locale)

Set the text locale list to a one-member list consisting of just the locale. See setTextLocales(android.os.LocaleList) for how the locale list affects the way the text is drawn for some languages.

Parameters
locale Locale: the paint's locale value for drawing text, must not be null.

setTextLocales

Added in API level 24
public void setTextLocales (LocaleList locales)

Set the text locale list. The text locale list affects how the text is drawn for some languages. For example, if the locale list contains Locale#CHINESE or Locale#CHINA, then the text renderer will prefer to draw text using a Chinese font. Likewise, if the locale list contains Locale#JAPANESE or Locale#JAPAN, then the text renderer will prefer to draw text using a Japanese font. If the locale list contains both, the order those locales appear in the list is considered for deciding the font. This distinction is important because Chinese and Japanese text both use many of the same Unicode code points but their appearance is subtly different for each language. By default, the text locale list is initialized to a one-member list just containing the system locales. This assumes that the text to be rendered will most likely be in the user's preferred language. If the actual language or languages of the text is/are known, then they can be provided to the text renderer using this method. The text renderer may attempt to guess the language script based on the contents of the text to be drawn independent of the text locale here. Specifying the text locales just helps it do a better job in certain ambiguous cases.

Parameters
locales LocaleList: the paint's locale list for drawing text, must not be null or empty.
